Note: Link stations do not have to be defined on every port, only those over
which you want to initiate connections to adjacent nodes.
5. Enable the APPN network node.
6. Configure the following parameters for the APPN network node:
vNetwork ID
vControl point name
7. Define the XID number for subarea connections parameter for the APPN
network node (optional).
8. Accept all other defaults
9. Optionally do the following:
vModify High-Performance Routing parameters
vConfigure Dependent LU Requester
vDefine connection networks
vDefine new COS names or mode name mappings
vTune the performance of this node
vPerform node service trace diagnostics
vCollect statistics for this network node
Controlling Connections Configuration
This group of APPN configuration steps:
vAllows the network node to accept requests only from nodes that you specify.
vEnables the network node to initiate connections with other nodes that you
specify, including LEN end nodes.
This configuration provides a higher level of security because you explicitly define
which APPN nodes may communicate with this router network node.A connection
request from an adjacent node will be accepted only if its fully qualified CP name
parameter has been configured on this network node. This group of configuration
steps optionally enables you to have a secure link with each adjacent node by
configuring the session level security feature for each link.
Use the following procedure for the controlling connections configuration:
1. Select ports over which you desire to establish connections to adjacent nodes
from the following DLC port types supported by APPN:
vToken-ringLAN port
vEthernet LAN port
vFrame-relay serial port
vPPP serial port
vX.25
vDLSw
vSDLC
vIP port
2. Define ports selected as direct APPN ports with the following parameters:
vEnable

APPN routing

on this port
vDisable the

service any port

parameter
3. If you are configuring APPN using a DLSw port:
vEnable bridging on the node
