Basic ATM Concepts

￿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>
