Do devices begin to register with the LES and BUS once multi-point signaling is turned off?
Check whether BUS is connected.

•
Check IISP routes to the switch containing the LES and BUS.
-
Are all IISP routes correct?
-
Does a new IISP route need to be added so devices can reach the LES and BUS?

TROUBLESHOOTING PNNI LINKS

You have physically connected another company's ATM switch with your SmartSwitch 6500. Each switch supports
PNNI, but there is no connectivity between the two devices. When dealing with PNNI connectivity, two possible
configurations must be considered:
•
The SmartSwitch 6500 and the other switch are in the same peer group
•
The SmartSwitch 6500 and the other switch are is different peer groups
Use the following procedures to diagnose and resolve PNNI connectivity problems.
9.3.1

Switches in Same Peer Group

Check the physical connection. Make sure that the switches are connected correctly.
1.
Check that both switches are in the same peer group. On the SmartSwitch 6500, enter the
2.
command to view the peer group ID. If not the same peer group, perform the following:
pnninode
-
Set the peer group ID on either switch to match the other. On the SmartSwitch 6500, use the
command to change the peer group ID.
pnnipeergroup
3. Check the signalling type of each switch. If either switch does not show PNNI as the signaling type
on the connecting port. Perform the following:
-
Turn off ILMI and manually set the signaling type to PNNI. On the SmartSwitch 6500, enter the
show portconfig
command to turn off ILMI and manually set signaling to
portconfig
If none of the above actions have corrected the problem, contact Cabletron Systems Customer
