Verify the following using

/ATM/SHOW/connection:

–

OAM is up.

–

SSCOP, and ILMI is up. (for SVC only)

–

A Trunk SVC or PVC connection is created per Trunk instance.

–

ATM port connection and signaling. Operational status, Line
state, Signaling status, and ILMI should be ‘up’. (for SVC only)

/ATM/CONFIG/MODIFY> port

Verify the connection up time is increasing and status is ‘active’

for a specific VCC using

VAC <VCC number>

Problem:

The Trunk connection is up and active but I cannot ping across the
ATM network.

Solution:

Use the following solutions:

Verify that all IP addresses, subnet masks, gateways are set correctly
on the VLANs and any attached devices.

Verify the ATM port service has been bounded to all VLANs. If not,
you will need to delete the Port service and re-create it.

/PORTSERV/CONFIG >remove <phyport#> <portserv#>

/PORTSERV/CONFIG/create 34

vps 34

Verify all ATM Trunk ports are in a ‘Forwarding’ state using

vvp.

Depending on Spanning Tree, this process may take up to 20 seconds.

When configuring a PVC connection, ensure the VCI values are
identical on the switches you are connecting to. Trunk ids do not need
to be the same. However, valid trunk ids range from 0 through 15.

/ATM/CONFIG/MODIFY >trunk <trunk id>
