circuit, then it is likely that the call request packet (sent out to establish

a link station) carries incorrect parameters. You should therefore carry

out the following checks:

Check following conﬁguration parameters:

Step 1. If you are setting up SNAplus2 to receive incoming calls then it is vital

that the X.25 software is set up to route these calls to SNAplus2. Check

that the

incoming_address

parameter (if used) is conﬁgured correctly

on the link station's port to match the local node's DTE address.

Check the port conﬁguration in one of the following ways:

• If you are using the Motif administration program, then zoom on the

port.

• If you are using the command-line administration program then issue

the snapadmin query_port command to view the port conﬁguration.

Step 2. Check whether the remote system requires particular facilities or user

data parameters. If it does, ensure that these are set appropriately in

your SNAplus2 conﬁguration of this link station.

Check the link station conﬁguration in one of the following ways:

• If you are using the Motif administration program, then zoom on the

link station.

• If you are using the command-line administration program then issue

the snapadmin query_ls command to view the link station

conﬁguration.

Step 3. Check that the remote DTE address matches the address of the remote

system.

Token Ring, Ethernet, or FDDILink Station Fails to Start If your

Token Ring, Ethernet, or FDDI link station failed to start, perform the

checks listed in “Link Station Fails to Start” before performing the

checks listed below.

Check the following link station parameters:

Step 1. Check that the remote MAC address, conﬁgured in the

mac_address

parameter, matches that of the remote system.

Step 2. Check that the local and remote SAP conﬁguration by doing the

following:
