– Verify signaling and ILMI status should be ‘up’.
/ATM/SHOW >port
Verify the following using /ATM/SHOW/connection:
– OAM is up.
– SSCOP, and ILMI is up. (for SVC only)
– A Pt-Pt SVC or PVC connection is created per PTOP 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 PTOP 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, and gateways are set
correctly on the VLANs and any attached devices
Verify the ATM port service has been bounded to each VLAN.
/PORTSERV/CONFIG/create 34
vps 34
Verify all ATMPTOP ports are in a ‘Forwarding’ state using vvp
If configuring PVC, ensure the VCI values are identical on the
switches you are connecting to.
Verify a PVC Pt-Pt connection is created.
/ATM/SHOW >connection
Note:
Depending on Spanning Tree, this process may take up to
