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 Advanced Peer-to-Peer Networking" chapter of the Bridging and IBM Networking Configuration Guide.
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. |
No partner nodes are specified.
APPN link station configuration
This command first appeared in Cisco IOS Release 11.0.
If the name configured with this command does not match the remote node's control point (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
You can use the master indexes or search online to find documentation of related commands.

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 (COS) name not among IBM default names. COS names must be a Type A character string. A Type A character string contains 1 to 8 of the following characters: |
There is no default class of service name.
If this command is not issued, an IBM default COS can be used. The IBM supplied default classes of service are #CONNECT, #BATCH, #INTER, #BATCHSC, #INTERSC, CPSVCMG, and SNASVCMG.
Global configuration
This command first appeared in Cisco IOS Release 11.0.
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

No default link station name is assigned.
Global configuration
This command first appeared in Cisco IOS Release 11.0.
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 predefined 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

IBM-defined [blank] mode
Global configuration
This command first appeared in Cisco IOS Release 11.0.
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
You can use the master indexes or search online to find documentation of related commands.

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. A fully qualified name is a string of 1 to 8 characters, a period, and another string of 1 to 8 characters. The following characters are acceptable: |
No default netid.luname is specified. You must supply a value; otherwise, the configuration will fail.
Global configuration
This command first appeared in Cisco IOS Release 11.0.
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
You can use the master indexes or search online to find documentation of related commands.

EXEC
This command first appeared in Cisco IOS Release 11.3.
The following example initiates a path switch:
appn path-switch connection 8000000000A06278
You can use the master indexes or search online to find documentation of related commands.
No default port name is specified. No default interface is provided. You must provide the port name and interface, or the configuration will fail.
Global configuration
This command first appeared in Cisco IOS Release 11.0.
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.
If you configure APPN to run over DLSw+, you specify vdlc, and must also use the vdlc APPN port configuration command to identify which ring group the APPN VDLC port uses and, optionally, which virtual MAC address is used as the local MAC address identifying this APPN port.
The following example associates an APPN port named FDDI0 with FDDI interface 0:
appn port FDDI0 fddi0 complete
In the following example, the appn port vdlc command creates an APPN VDLC port named "vdlcport," and the vdlc APPN port configuration command identifies the ring group (100) and VDLC virtual MAC address (4000.3745.000):
appn port VDLCPORT vdlc vdlc 100 vmac 4000.3745.0000 complete

Use the central-resource-registration APPN control point configuration command to enable the central resource registration function. Use the no form of this command to disable the central resource registration function.
central-resource-registrationThis command has no arguments or keywords.
The central resource registration function is enabled.
APPN control point configuration
This command first appeared in Cisco IOS Release 11.2.
By default, the central resource registration function is enabled in the router so that registration of downstream resources in the central directory server will be attempted by the router when it receives a request from the control point that owns the resource. If there is unpredictable behavior related to the central resource registration or central directory server, use the no central-resource-registration command to disable the central resource registration function. In normal circumstances there should not be any reason to disable the central resource registration function.
The following example disables the central resource registration function:
appn control-point neta.router no central-resource-registration complete
You can use the master indexes or search online to find documentation of related commands.
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.

The default value specified in the appn port command.
APPN link station configuration
This command first appeared in Cisco IOS Release 11.0.
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

cost-per-byte cost
cost | Number in the range 0 to 255. The default is 0. |
The default cost is 0.
APPN port configuration
This command first appeared in Cisco IOS Release 11.0.
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 value 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 serial 0 cost-per-byte 100 complete
You can use the master indexes or search online to find documentation of related commands.

The default value specified in the appn port command.
APPN link station configuration
This command first appeared in Cisco IOS Release 11.0.
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
You can use the master indexes or search online to find documentation of related commands.
appn link-station

Use the cp-cp-sessions-supported APPN link station configuration command to specify that a control point-control point (CP-CP) session can be established over this connection. Use the no form of this command to specify that a CP-CP session cannot be established over this link.
cp-cp-sessions-supportedThis command has no arguments or keywords.
CP-CP sessions are supported.
APPN link station configuration
This command first appeared in Cisco IOS Release 11.0.
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

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
