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:
A-Z, a-z
0-9
$ # @

Defaults

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.

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 #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

Command Mode

Global configuration

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:

appn link-station CISCO1
  port TR0
  lan-destination-address 0200.0000.0001

appn mode modename
no appn mode modename

Syntax Description

modename

Name of the mode. A Type A character string. A Type  A character string contains 1 to 8 of the following characters:
A-Z, a-z
0-9
$ # @

Default

IBM-defined [blank] mode

Command Mode

Global configuration

Usage Guidelines

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.

Example

The following example changes the IBM-defined mode #BATCH to use the #CONNECT class of service:

appn mode #BATCH
  class-of-service #CONNECT

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
no appn partner-lu-location netid.luname

Syntax Description

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:
A-Z, a-z
0-9
$ # @
The first character of either string must not be a number.

Default

No default netid.luname is specified. You must supply a value; otherwise, the configuration will fail.

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:

appn partner-lu-location CISCO.LU21
  owning-cp CISCO.CP2
  complete

appn port

Use the appn port global configuration command to define an APPN port and relate it to a previously defined interface. Use the no form of this command to cancel the APPN port definition.

appn port portname {interface | rsrb | vdlc}
no appn port portname

Syntax Description

portname

Port name to be associated with the interface.

interface

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.

vdlc

Specify vdlc to allow link stations using this virtual port to connect over DLSw+, or any other higher-layer protocol that is CLSI-compliant, using virtual data-link control (VDLC).

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 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

Default

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-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.

null-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-poll

Syntax 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:

appn port FDDI0 fddi 0
  null-xid-poll

vdlc

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. Use the no form of this command to delete the configuration.

vdlc ring-group [vmac vdlc-mac-address]
no vdlc ring-group [vmac vdlc-mac-address]

Syntax Description

ring-group

Ring group number matching the number you specified with the source-bridge ring-group command. The valid range is 1 to 4095.

vmac vdlc-mac-address

(Optional) Virtual MAC address used as the local MAC address identifying this APPN port.

Default

No defaults are defined.

Command Mode
