Command Mode
Global configuration
Usage Guidelines
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.
Example
The following example defines a COS with one node row and one tg row:
appn class-of-service #SECUREnode-row 1 weight 5 congestion no no route-additional-resistance 0 255tg-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 255completeRelated Commands

Usage Guidelines
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.
Example
The following example defines a link station using port TR0:

Command Mode
Global configuration
Usage Guidelines
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.
Example
The following example defines the location of an LU named CISCO.LU21:

Defaults
No default port name is specified. No default interface is provided. You must provide the port name and interface, or the configuration will fail.
Command Mode
Global configuration
Usage Guidelines
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.
Examples
The following example associates an APPN port named FDDI0 with FDDI interface 0:
appn port FDDI0 fddi0completeIn 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):

The default cost is 0.
Command Mode
APPN port configuration
Usage Guidelines
This command first appeared in Cisco IOS Release 11.0.
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 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 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.
Example
The following example sets the cost per connect time to 100:

This command first appeared in Cisco IOS Release 11.0.
You can define up to 8 rows. Each row represents the characteristics of a node that meets the requirements for this class of service and defines a weight for the node that will be used in calculating the cost of a total route.
If the congestion maximum is set to "no," the congestion minimum must also be set to "no."
Example
The following example defines an APPN class of service with one node row:
appn class-of-service #SECUREnode-row 1 weight 5 congestion no no route-additional-resistance 0 255tg-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 255completeRelated Commands

show appn class-of-servicenull-xid-poll
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-poll
no null-xid-pollSyntax Description
This command has no arguments or keywords.
Default
XID3 negotiation is used to poll remote devices.
Command Mode
APPN port configuration
Usage Guidelines
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.
Example
The following example specifies that null XID should be used to poll the remote nodes associated with the APPN port FDDI0.
