Troubleshooting LAN Emulation
Troubleshooting
4.
Check ILMI, UNI routes, and PVCs (if applicable).
•
If using SVCs, use
show ATMRoute
to check whether static UNI routes are correct and whether
dynamic UNI routes are established and correct. If dynamic routes are incorrect or missing, try
creating static routes instead.
•
If using PVCs, use
show pvc
to check if PVCs connect the correct resources through the correct
ports.
•
If using PVCs, use
show ipatmpvc
to check if local switch clients are mapped to the correct end node
IP addresses.
5.
If working through these questions does not solve the problem, contact Cabletron Systems Customer
Service. (See Appendix C, “Technical Support.”)
5.2
TROUBLESHOOTING LAN EMULATION
You have configured an Emulated LAN and your network applications are not working. Use these questions and tests
to help determine the cause of the problem.
1.
Check for connectivity. Try pinging between end nodes. Ping from the SmartSwitch 9A100 (using
start ping
) to its end nodes. If you cannot ping, check physical connectivity (disconnected cable
and so on).
2.
Check IP routes and addresses.
•
Use
show route
command to check the SmartSwitch 9A100 route table.
-
Are the destination addresses correct for the specified gateways?
-
Are there any routing loops?
-
Are one or more of the destination addresses mapped to the wrong subnet?
•
Use
show client
to check the SmartSwitch 9A100 local ELAN client.
-
Does the client have the correct IP address?
-
Is the subnet correct?
-
Is the ATM address correct?
-
Is the server type correct?
•
Check end nodes configurations.
-
Are end nodes configured correctly?
3.
If the ELAN spans multiple switches, check the following:
-
Is the LECS address correct on all switches?
-
Can all switches reach the switch providing LECS support?
-
If using the Well Known LECS Address, are all switches correctly mapped?
4.
Check the LECS database.
•
Use
show lecselan
to check the names and numbers of ELANs.
-
Are ELAN names correct?
-
Is the ATM address of the LES correct?
