This chapter describes the commands to configure and monitor the Advanced Peer-to-Peer Networking (APPN) feature. For APPN configuration tasks and examples, refer to the "Configuring APPN" chapter of the Router Products Configuration Guide.
Note: This chapter introduces seven new command modes:
Use the adjacent-cp-name APPN link station configuration command to specify the name of the partner node for the link station. Use the no form of this command to delete the definition.
adjacent-cp-name netid.cpname
netid.cpname | Fully qualified network name of the remote control point. |
The default state is no adjacent-cp-name.
APPN link station configuration
If the name configured with this command does not match the remote node's CP name, the link will not come up. If the no form of the command is issues, or the command is not issued at all, no checking is done. This command must be specified if the adjacent node is LEN.
The following example defines a link station that specifies the name of the partner node:
appn link-station APPN1 port TR0 lan-dest-address 1000.C4C1.E5C5 adjacent-cp-name CISCO.APPN1 complete
appn link-station
show appn link-station
Use the appn class-of-service global configuration command to define an APPN class of service that is not an IBM-supplied default. Use the no form of this command to delete the definition. This command begins the APPN class of service configuration command mode.
appn class-of-service cosname
cosname | Class of service name not among IBM default names. Class of service names must be a Type A character string. A Type A character string is a string of 1 to 8 of the following characters: |
There is no default class of service name.
If this command is not issued, an IBM default class of service can be used. The IBM supplied default classes of service are #CONNECT, #BATCH, #INTER, #BATCHSC, #INTERSC, CPSVCMG, and SNASVCMG.
Global configuration
Class of Service (COS) is a definition of the transport network characteristics that should be used to establish a particular session. The COS definition assigns relative values to factors such as acceptable levels of security, cost per byte, cost per connect-time, propagation delay, and effective capacity. APPN network nodes use COS to select the best session routes between LUs.
If one of the IBM default classes of service does not meet the needs of a particular network, the appn class-of-service global configuration command can be used to create a user defined definition.
The following example defines a COS with one node row and one tg row:
appn class-of-service #SECURE node-row 1 weight 5 congestion no no route-additional-resistance 0 255 tg-row 1 weight 30 byte 0 255 time 0 255 capacity 0 255 delay 0 255 security 200 255 user1 0 255 user2 0 255 user3 0 255 complete
node-row
show appn class-of-service
tg-row
transmission-priority
Use the appn connection-network global configuration command to specify the fully qualified network name for the connection network. Use the no form of this command to delete the definition. This command begins the APPN connection network configuration command mode.
appn connection-network netid.cnname
netid.cnname | Fully qualified network name for the connection network. cnname is the name of the virtual network node in the connection network. |
No default connection network name is assigned.
Global Configuration
The connection network name must be the same on all nodes that define the connection network, and must be different from any other connection network, LU, or control point in the total network.
The following example defines a connection network using APPN port TR0:
appn connection-network CISCO.CAPPN1 port TR0 complete
port (APPN connection network)
show appn connection-network
Use the appn control-point global configuration command to specify the fully qualified control point name for the node. Use the no form of this command to delete the name and clear all APPN definitions. This command begins the APPN control point configuration command mode.
appn control-point netid.cpname
netid.cpname | Fully qualified control point name for the local node. |
No default control point name is assigned.
Global configuration
You must issue the appn control-point command to activate APPN routing. There can be only one control point definition in the system. The control point name must be unique in the network.
The following example defines a control point named CISCO.APPN1:
appn control-point CISCO.APPN1 complete
appn routing
appn start
appn stop
backup-dlus (APPN control point)
buffer-percent
dlur (APPN Control Point)
dlus (APPN control point)
interrupt-switched
max-cached-entries
max-cached-trees
maximum-memory
route-additional-resistance
safe-store-cycle
safe-store-host
safe-store-interval
show appn node
xid-block-number
xid-id-number
Use the appn link-station global configuration command to assign the name of an adjacent link station. Use the no form of this command to delete the link station name. This command begins the APPN link station configuration command mode.
appn link-station linkname
linkname | Name that identifies the link station. The name must be a Type A string. |
No default link station name is assigned.
Global configuration
A link represents a connection between a local link station and a link station in an adjacent node. The link can be considered a direct connection between two distinct Type 2.1 or Type 2.0 nodes. The link station provides a route over which local sessions or intermediate sessions can pass. Two link stations are required to build a link: one on each node.
A link station can be pre-defined with the appn link-station command, or dynamically defined. If you specify service-any in the associated appn port command, link-stations can be dynamically defined when a connect request is received. In this case, the appn link-station command would not be required. You must define an APPN link station if you intend this node to initiate the connection to the adjacent node.
The following example defines a link station using port TR0:
appn link-station CISCO1 port TR0 lan-destination-address 0200.0000.0001 complete
adjacent-cp-name
backup-dlus (APPN link station)
connect-at-startup
cost-per-byte (APPN link station)
cost-per-connect-time (APPN link station)
cp-cp-sessions-supported
dlur-dspu-name

x25-dest-address
Use the appn mode global configuration command to specify a new mode or to change an IBM defined mode and identify the class of service associated with the mode name. Use the no form of this command to delete the previous definition.This command begins the APPN mode configuration command mode.
appn mode [modename]
modename | Name of the mode. A Type A character string. |
IBM defined [blank]
Global configuration
The IBM defined modes are #BATCH, #BATCHSC, #INTER, #INTERSC, #CPSVCMG, #SNASVCMG, #CPSVRMG, and [blank]. These definitions can not be changed.
This command is required when LEN nodes are using this node for network services. The LEN node will issue a BIND containing this mode name; this command will be used to associate the mode name with a COS name.
The following example changes the IBM defined mode #BATCH to use the #CONNECT class of service:
appn mode #BATCH class-of-service #CONNECT complete
class-of-service
show appn mode
Use the appn partner-lu-location global configuration command to specify an LU that would be the destination LU for an LU-LU session request from an LU using this node for network services. Use the no form of this command to delete the previous definition. This command begins the APPN partner LU configuration command mode.
appn partner-lu-location netid.luname
NETID.LUNAME | Fully qualified name of the partner LU. |
No default NETID.LUNAME is specified. You must supply a value; otherwise the configuration will fail.
Global configuration
Use this command to define an entry in the directory database. This command improves network performance by allowing directed LOCATE (because the partner name is known), instead of a broadcast. The disadvantage is that definitions must be created. Alternatively, partner names can be discovered dynamically and added to the database as they are learned. This process, however, requires either prior sessions to the node or broadcast traffic (which causes additional network traffic) sent to locate the node.
The following example defines the location of an LU named CISCO.LU21:
appn partner-lu-location CISCO.LU21 owning-cp CISCO.CP2 complete
owning-cp
serving-nn
show appn directory
wildcard
Use the appn port global configuration command to define an APPN port and relate it to a previously defined interface.
appn port portname {type number | rsrb}
portname | Port name to be associated with the interface. |
type number | Previously defined interface type and number with which the port name is to be associated. |
rsrb | Specify rsrb instead of an interface if this port will utilize RSRB as a transport protocol. |
No default port name is specified. No default interface is provide. Both must be provided or the configuration will fail.
Global configuration
At least one APPN port must be defined for each interface that will participate in APPN routing. If more that one service access point (SAP) will be used over a particular port, then a port must be defined for each SAP.
The following example associates an APPN port named FDDI0 with FDDI interface 0:
appn port FDDI0 fddi0 complete
A dagger () indicates that the command is documented in another chapter.
appn start port
appn stop port
cost-per-byte (APPN port)

sdlc-sec-addr
show appn port
user-defined-1 (APPN port)
user-defined-2 (APPN port)
user-defined-3 (APPN port)
x25-subaddress
Use the appn routing global configuration command to indicate that APPN routing should be activated. Use the no form to deactivate APPN routing.
appn routingThis command has no arguments or keywords.
The default state is no appn routing.
Global configuration
For appn routing to complete successfully, an APPN control point must be configured using the appn control-point global configuration command.
The following example specifies that APPN routing should be started:
appn routing
appn control-point
appn start
appn stop
Use the appn start EXEC command to activate the APPN subsystem in this node.
appn startThis command has no arguments or keywords.
This command has no default state.
EXEC
The following example activates APPN:
appn start
Use appn start link-station to activate a logical APPN link.
appn start link-station linkname
linkname | The name of the link-station. Must be a Type A character string. |
No default is provided for linkname.
EXEC
The following example activates an APPN link station:
appn start link-station TR0
appn link-station
appn stop link-station
show appn link-station
Use the appn start port EXEC command to activate APPN routing over a particular port.
appn start port portname
portname | The name of the port. Must be a Type A character string. |
No default is provided for portname.
EXEC
This command is also used when the APPN subsystem is already started and a port is added or a characteristic is changed by subcommand.
The following example activates APPN routing over port TR0:
appn start port TR0
appn port
appn stop port
show appn port
This command will deactivate APPN routing without affecting the current configuration.
appn stopSyntax Description
This command has no arguments or keywords.
This command has no default state.
EXEC
The following command deactivates APPN routing:
appn stop
appn control-point
appn routing
appn start
Use the appn stop link-station EXEC command to deactivate an APPN connection between the local node and an adjacent node.
appn stop link-station linkname
linkname | The name of the link station. The name must be a Type A character string. |
There is no default provided for linkname.
EXEC
The following command deactivates an APPN link between the local node and an adjacent node:
appn stop link-station APPN1
appn link-station
appn start link-station
Use appn stop port to deactivate APPN routing over a specified port.
appn stop port portname
portname | The name of the port. Must be a Type A character string |
No default is provided for portname.
EXEC
For a port deactivation to be successful, no APPN link station can be active on that port.
The following example deactivates APPN routing over port TR0:
appn stop port TR0
Use the backup dlus APPN control point configuration command to specify the name of the default backup DLUS, which performs SSCP services for downstream PUs if the default DLUS is unable to provide the services. Use the no form of this command to delete the definition.
backup-dlus NETID.CPNAME
NETID.CPNAME | Fully qualified network name. |
This default state is no backup-dlus.
APPN control point configuration
You must specify dlur and dlus (control-point) before you can specify backup-dlus. You can use the backup-dlus link station configuration command to override this command for a particular link station.
The following example defines an APPN control point with a backup DLUS:
appn control-point CISCO.ROUTER dlur max-pus 100 dlus CISCO.APPN1 backup-dlus CISCO.APPN2 complete
appn control-point
backup-dlus (APPN link station)
dlur (APPN control point)
Use the backup-dlus APPN link station configuration command to specify the default backup DLUS node that provides SSCP services to the downstream PUs of the link in the event that the DLUS is unable to provide the DLUR function. Use the no form of this command to delete the definition.
backup-dlus NETID.CPNAME
NETID.CPNAME | Fully qualified network name. |
The default state is no backup-dlus.
APPN link station configuration
You must specify the dlur and dlus APPN control point commands before you can specify backup-dlus. You can use the backup-dlus link station configuration command on the link station to override this command for that particular link station.
The following example specifies the backup DLUS node for a link station:
appn link-station CISCO.HOST port FDDI0 lan-dest-address 0200.0000.1234 dlus CISCO.APPN1 backup-dlus CISCO.APPN3 complete
appn link-station
backup-dlus (APPN control point)
dlus (APPN control point)
dlus (APPN link station)
Use the buffer-percent APPN control point configuration command to specify the percent of buffers that are reserved for use by APPN. Use the no form of this command to cancel the buffer reservation.
buffer-percent number
number | The maximum percentage of I/O memory that APPN is allowed to allocate for buffers. The valid range is 1 to 100 percent. |
The default is 100 percent.
APPN control point configuration
Use the buffer-percent command to ensure that APPN will not monopolize the router's buffers. If other protocols are to be routed through the local node, this command can be utilized to reserve buffers for protocols other than APPN.
The following example limits APPN's buffer usage to 25% of the router's buffers:
appn control-point CISCO.ROUTER buffer-percent 25 complete
A dagger () indicates that the command is documented in another chapter.
appn control-point
show buffers
show memory
Use the class-of-service APPN mode configuration command to specify the class of service that maps to a particular mode name. Use the no form of this command to delete the definition.
class-of-service cosname
cosname | The name of the class of service. Must be a Type A character string. |
The default class-of-service name is #CONNECT.
APPN mode configuration
LEN nodes use this node for network services. The mode name is passed in the BIND and this command is used to correlate the mode name to a class-of-service name.
The following example defines a mode with class of service #INTER:
appn mode MAPPN1 class-of-service #INTER complete
Use the connect-at-startup APPN link station configuration command to specify that the link will call out to the partner and attempt to bring up the link when the link's definition is complete. Use the no form of this command to delete the definition.
connect-at-startupThis command has no arguments or keywords.
The default state is connect-at-startup.
APPN link station configuration
The following example deactivates call out for APPN link station ETHER12:
appn link-station ETHER12 appn port ETHER1 lan-dest-address 0200.0000.4321 no connect-at-startup complete
Use the cost-per-byte APPN link station configuration command to specify the cost-per-byte of transmitting a byte of data over this connection. Use the no form of this command to delete the definition.
cost-per-byte cost
cost | Number in the range 0 to 255. |
The default value specified in the appn port command.
APPN link station configuration
Use this command to specify the relative cost to transmit a byte over the link. The relative cost per byte is used in route selection. Cost per byte may be specified at the port level, in which case it applies to all link stations that connect through the port. Cost per byte specified at the link station level overrides the cost per byte specified at the port level, and relates to the defined link station only. This value is compared to the values specified for a class of service to determine if this link can be used to support the class of service.
The following example sets the cost per byte value to 10:
appn link-station CISCO1 port RSRB1 lan-dest-address 1000.2020.0211 cost-per-byte 10 complete
appn link-station
cost-per-byte (APPN port)
show appn link-station
Use the cost-per-byte APPN port configuration command to specify the cost per byte of transmitting a byte of data through this port. Use the no form of this command to delete the definition.
cost-per-byte cost
cost | Number in the range 0 to 255. |
The default cost is 0.
APPN port configuration
Specifying cost-per-byte at the port level applies to all link stations accessed through this port, unless cost-per-byte is specified on an individual appn link-station command. Specifying this on the appn link-station command overrides the port value. The cost is used in route selection for a particular class of service. Cost per byte specified at the link station level overrides the cost per byte specified at the port level, and relates to the defined link station only. This value is compared to the values specified for a class of service to determine if this link can be used to support the class of service.
The following example sets the cost per byte value to 10:
appn port FR0 Serial0 cost-per-byte 100 complete
appn port
cost-per-byte (APPN link station)
show appn port
Use the cost-per-connect-tine APPN link station configuration command to specify the relative cost of the link. Use the no form of this command to delete the definition.
cost-per-connect-tine cost
cost | Number in the range 0 to 255. |
The default value specified in the appn port command.
APPN link station configuration
The relative cost of the link, which typically reflects the tariff of the transmission facility, is used in route selection. Cost per connect time may be specified at the port level, in which case it applies to all link stations that connect through the port. Cost per connect time specified at the link station level overrides the cost per connect time specified at the port level, and relates to the defined link station only. This value is compared to the values specified for a class of service to determine if this link can be used to support the class of service.
The following example sets the cost per connect time to 100:
appn link-station CISCO4 port FDDI0 cost-per-connect-time 100 complete
appn link-station
cost-per-connect-time (APPN port)
show appn link-station
Use the cost-per-connect-time APPN port configuration command to specify the cost per connect time. Use the no form of this command to delete the definition.
cost-per-connect-time cost
cost | Number in the range 0 to 255. |
The default cost is 0.
APPN port configuration
Specifying cost-per-connect-time at the port level applies to all link stations accessed through this port, unless cost-per-connect-time is specified on an individual appn link-station command. Specifying this on the appn link-station command overrides the port value. The cost is used in route selection for a particular class of service. Cost per connect time specified at the link station level overrides the cost per connect time specified at the port level, and relates to the defined link station only. This value is compared to the values specified for a class of service to determine if this link can be used to support the class of service.
The following example sets the cost per connect time to 100:
appn port SDLC0 Serial1 cost-per-connect-time 100 complete
appn port
cost-per-connect-time (APPN link station)
show appn port
Use the cp-cp-sessions-supported APPN link station configuration command to specify that a CP - CP session can be established over this connection. Use the no form of this command to specify that a CP - CP session can not be established over this link.
cp-cp-sessions-supportedThis command has no arguments or keywords.
CP - CP sessions are supported.
APPN link station configuration
The no form of this command must be specified for a link to a LEN node.
CP sessions to additional NNs are optional. Having fewer CP - CP sessions reduces the number of topology update messages and memory required, while increasing convergence time (the time required to update all network nodes).
The following example specifies that no CP - CP sessions are supported:
appn link-station FDDI41 port FDDI1 lan-dest-address 0400.0000.2323 no cp-cp-sessions-supported complete
appn link-station
show appn link-station
verify-adjacent-node-type
Use the desired-max-send-btu-size APPN port configuration command to specify the maximum BTU size on this link. Use the no form of this command to delete the definition.
desired-max-send-btu-size size
size | Number in the range 99 to 32767. |
The default size is 1024 bytes.
APPN port configuration
The MTU size must be big enough to accommodate the configured size of the BTU.
The following example sets the maximum BTU size to 4000:
appn port TR0 TokenRing0/0 desired-max-send-btu-size 4000 complete
A dagger () indicates the command is documented in another chapter.
Use the dlur APPN control point configuration command to specify that the Dependent LU Requestor (DLUR) function is supported on this CP. Use the no form of this command to delete the definition.
dlur [max-pus number]
max-pus number | (Optional) Maximum number of physical units (PUs) served by this DLUR, in the range 1 to 100000. There is no default. If max-pus is not specified, there is no limit on the number of PUs served by this DLUR. |
If the dlur command is not specified, the DLUR function is not supported on this CP. If max-pus is not specified, there is no limit on the number of PUs served by this DLUR.
APPN control point configuration
The following example specifies the DLUR function on the CPand specifies that the maximum number of PUs served by this DLUR is 100:
appn control-point CISCO.ROUTER dlur max-pus 100 dlus CISCO.HOST complete
appn control-point
dlus (APPN control point)
show appn dlur-lu
show appn dlur-pu
show appn dlus
Use the dlur-dspu-name APPN link station configuration command to specify the name of the downstream PU connected by this link. Use the no form of this command to delete the definition.
dlur-dspu-name puname
puname | Type A character string. |
No default name is specified.
APPN link station configuration
The DLUR function requires the specification of the DSPU name for a PU2.0 node. Specification is also required when the DLUR function must activate the link to a PU2.1 or PU2.0 node, when driven by a host-initiated PU activation, and when the link to the PU is not active.
The following example specifies the DSPU name of a downstream node:
appn link-station LINK4 port TR1 lan-dest-address 1000.2020.0211 dlur-dspu-name PU003334 pu-type-20 complete
appn link-station
dlur (APPN Control Point)
dlus (APPN link station)
Use the dlus APPN control point configuration command to specify the name of the default Dependent LU Server (DLUS) that provides SSCP services to the downstream PUs. Use the no form of this command to delete the definition.
dlus netid.cpname
netid.cpname | Fully qualified CP name. |
No default DLUS is defined.
APPN control point configuration
dlur must be specified in the CP command if dlus is specified. The name of the node-default DLUS should be specified when supporting downstream PUs that request or require ACTPUs, DLUR does not currently have an active session with the DLUS, and when no DLUS or back-up DLUS name has been provided on the APPN link station definition.
The following example defines the DLUS:
appn control-point CISCO.ROUTER1 dlur dlus CISCO.APPN1 complete
appn control-point
dlur (APPN Control Point)
dlus (APPN link station))
show appn dlur-lu
Use the dlus APPN link station configuration command to specify the name of the default Dependent LU Server (DLUS) node that provides SSCP services to the downstream PUs of this link station. Use the no form of this command to delete the definition.
dlus netid.cpname
netid.cpname | Fully qualified CP name. |
The default state is no dlus.
APPN link station configuration
The dlus command is used to override the value of dlus specified in the control point definition.
The following example specifies the DLUS for a specific APPN link station:
appn link-station LINK5 port TR1 lan-dest-address 0200.0000.5678 dlus CISCO.APPN1 complete
appn control-point
dlur (APPN Control Point)
dlus (APPN control point)
show appn dlus
Use the effective-capacity APPN link station configuration command to specify the bit rate for the connection. Use the no form of this command to delete the definition.
effective-capacity number
number | Number in the range 0 to 100000000, specifying bits per second. |
The value specified in the appn port command.
APPN link station configuration
The bit rate is compared to the class of service requirements when selecting routes. This can be specified on the link station command to identify the bit rate for this link station only. This value overrides the value specified on the port command. Effective capacity is used by the node to determine the least cost route for APPN intermediate sessions.
The following example defines the effective capacity:
appn link-station FRLINK44 port FR0 fr-dest-address 44 effective-capacity 4000000 complete
appn link-station
effective-capacity (APPN port)
show appn link-station
Use the effective-capacity APPN port configuration command to specify the effective capacity of a link. Use the no form of this command to delete the definition.
effective-capacity capacity
capacity | Number in the range 0 to 100000000 specifying bits per second (bps). |
The default is media dependent:
Ethernet | 10,000,000 bps |
FDDI | 100,000,000 bps |
Frame Relay | 56,000 bps |
QLLC | 56,000 bps |
RSRB | 56,000 bps |
SDLC | 56,000 bps |
Token Ring | 16,000,000 bps |
APPN port configuration
Specifying this command at the port level identifies the capacity for all link stations accessed through this port. Specifying this command on the link station command overrides the port value. This command also specifies the value for dynamically created transmission groups. The cost is used in route selection for a particular class of service.
The following example defines the effective capacity:
appn port FR0 Serial1/1 effective-capacity 2000000 complete
appn port
effective-capacity (APPN link station)
show appn port
Use the fr-dest-address APPN link station configuration command to specify the address of the partner node for Frame Relay links. Use the no form of this command to delete the definition.
fr-dest-address dlci [sap]
dlci | Number in the range 16 to 1007 that represents the DLCI, or virtual circuit, for a Frame Relay connection. |
sap | 1-byte hexadecimal number in the range 04 to ec, and divisible by 4. |
No default DLCI is provided.
The default SAP is 04 (hexadecimal)
APPN link station configuration
The command should be specified only if the APPN port used by the link station is a Frame Relay port.
The following example specifies DLCI 100:
appn link-station FRLNK100 port FR0 fr-dest-address 100 complete
appn link-station
lan-dest-address
sdlc-dest-address
show appn link-station
Use the interrupt-switched APPN control point configuration command to specify that ISR should be processed at the interrupt level.
interrupt-switchedThis command has no arguments or keywords.
The default state is no interrupt-switched.
APPN control point
This command improves the performance of ISR routing. The command can be used only if segment size is the same on all nodes in the message path. Re-segmenting cannot be accomplished at the interrupt level. In addition, this command should only be used when routing between interfaces with similar speeds. This is because no pacing is done in the node when interrupt-switched is specified.
The following example specifies that ISR should be processed at the interrupt level:
appn control-point CISCO.APPN1 interrupt-switched complete
appn control-point
show appn intermediate-session
Use the lan-dest-address APPN link station configuration command to specify the MAC address of the partner node. Use the no form of this command to delete the definition.
lan-dest-address lan-addr [sap]
lan-addr | 12-byte hexadecimal number in the form xxxx.xxxx.xxxx |
sap | 1-byte hexadecimal number in the range 04 to ec, and divisible by 4. |
No default lan-addr is specified.
The default SAP is 04 (hexadecimal).
APPN link station configuration
This command is required for interface types Token Ring, Ethernet, or FDDI. It is not allowed for other interface types.

Use the null-xid-poll APPN port configuration command to specify that the null XID should be used to poll the remote node associated with this APPN port. Use the no form of the command to cancel the specification.
null-xid-pollThis command has no arguments or keywords.
XID3 negotiation is used to poll remote devices.
APPN port configuration
This command first appeared in Cisco IOS Release 11.2.
The null-xid-poll command permits PU 2.0 devices that connect in with XID0 to build a dynamic link station. It is no longer necessary to configure a link definition. When this command is used, the router expects its partner to reveal its identity first by responding with either XID3 or XID0.
This feature works in a mixed environment of PU 2.0 and PU 2.1 devices where the same APPN port is shared by both types of devices. By default, XID3 is used to poll the devices. When a PU 2.0 device responds with XID0, the link is created and established dynamically. PU 2.1 devices are not affected by this change, and go through the XID3 negotiation as usual.
Some care must be exercised when configuring null-xid-poll: If two Cisco APPN network node routers connect across ports configured with null-xid-poll, the APPN connection will fail because both routers expect the other to respond first using either XID0 or XID3. Similar behavior may occur when a port configured with null-xid-poll attempts communication with a front-end processor configured for XID polling. You only need to configure null-xid-poll when dealing with a PU 2.0 device that does not respond gracefully to the XID3 poll.
The following example specifies that null XID should be used to poll the remote nodes associated with the APPN port FDDI0.
appn port FDDI0 fddi 0 null-xid-poll complete

user-defined-2 value
value | Number in the range 0 to 255 used to specify the relative value. |
128
APPN port configuration
This command is specified for defined transmission groups (with the appn link-station command) if the command has not been specified at that level. This command also specifies the value for dynamically created transmission groups. The cost is used in route selection for a particular class of service.
The following example defines a port with a user-defined-2 value of 50.
appn port ETHER1 user-defined-2 50 complete
Use the user-defined-3 APPN port configuration command to specify the relative value for a network-unique transmission group characteristic. Use the no form of this command to delete the definition.
user-defined-3 value
value | Number in the range 0 to 255 used to specify the relative value. |
128
APPN port configuration
This command is specified for defined transmission groups (with the appn link-station command) if the command has not been specified at that level. This command also specifies the value for dynamically created transmission groups. The cost is used in route selection for a particular class of service.
The following example defines a port with a user-defined-3 value of 50.
appn port ETHER1 user-defined-3 50 complete
Use the verify-adjacent-node-type APPN link station configuration command to specify that the adjacent node type must be verified as a requirement of link activation. Use the no form of this command to delete the definition.
verify-adjacent-node-type {learn | len | nn}
learn | Any adjacent node type is accepted. |
len | Only LEN adjacent node type is accepted. |
nn | Only NN adjacent node type is accepted. |
The default node type is learn.
APPN link station configuration
If the adjacent node type is LEN, the cp-cp-sessions-supported command must specify no.
If the adjacent node type is LEN, the adjacent-cp-name must be specified.
There is no verification for type EN
The following example specifies that any adjacent node type is accepted:
appn link-station NN4 port ETHER1 lan-dest-address 0200.5672.3212 verify-adjacent-node-type nn complete
appn link-station
show appn link-station
Use the wildcard APPN partner-lu-location configuration command to specify this entry as a "wildcard." Use the no form of this command to delete the previous definition.
wildcardThis command has no arguments or keywords.
The default state is no wildcard.
APPN partner LU location configuration
A wildcard entry serves any LU whose name matches the configured name up to the length of the configured name. Without an LU name and wildcard specified, the entry services all LUs.
The following example defines a wildcard that represents any LU that starts with LU2, such as LU21, LULU21, LU234, and so on:
appn partner-lu-location LU2 owning-cp CISCO.CP2 wildcard complete
appn partner-lu-location
show appn directory
Use the x25-dest-address to configure APPN over QLLC. Use the no form of this command to delete the configuration.
x25-dest-address [pvc | svc] x25-addr
pvc | (Optional) Use x25 permanent virtual circuit. |
svc | (Optional) Use x.25 switch virtual circuit. |
x25-addr | The x.25 destination link station address. |
No default address is specified.
APPN link station configuration
x25-addr must be a valid X.121 address. This address must match that assigned by the X.25 network service provider.
The following example configures the X.25 destination address:
appn link-station QLLC port QLLC1 x25-dest-address 170090 complete
appn link-station
show appn link-station
Use the x25-subaddress command to configure APPN over QLLC. Use the no form of this command to delete the configuration.
x25-subaddress [pvc | svc] x25-addr
pvc | (Optional) Use x25 permanent virtual circuit. |
svc | (Optional) Use x.25 switch virtual circuit. |
x25-addr | The x.25 sub-address from which data is received. |
No default address is assigned.
APPN port configuration
x25-addr must be a valid X.121 address. This address must match that assigned by the X.25 network service provider.
The following example configures the X.25 subaddress from which data is received:
appn port QLLC1 Serial0/1 x25-subaddress svc 0001121 complete
Use the xid-block-number APPN control point configuration command to specify the first 3 digits of the node identifier for the local node. Use the no form of this command to delete the definition.
xid-block-number number
number | A 3 digit hexadecimal number in the range 000 to fff. |
077 (hexadecimal)
APPN control point configuration
A unique ID is required for links to older versions of VTAM.
The following example specifies XID block number 456:
appn control-point CISCO.ROUTER xid-block-number 456 complete
appn control-point
show appn node
Use the xid-id-number APPN control point configuration command to specify the last five digits of the node ID for the local node. Use the no form of this command to delete the previous definition.
xid-id-number number
number | A 5 digit hexadecimal number in the range 00000 to fffff. |
00000 (hexadecimal)
APPN control point configuration
The XID ID and block numbers are included in XID exchanges and alert information, and are required for communicating with older versions of VTAM.
The following example specifies XID ID number 0cab7:
appn control-point CISCO.ROUTER xid-id-number 0cab7 complete
appn control-point
