Troubleshooting
If you want to execute multiple script commands regardless of individual command failure, you must
catch the exception thrown in each command. For example, a script action:
catch {do Command1}
catch {do Command2}
will execute Command2 even if command1 fails. For detailed information on how to use the Tcl script,
consult the Tcl man pages or Help file at
http://www.tcl.tk .
ESRP Manager
Problem: None of the member VLANs of an ESRP group are appearing in the ESRP Manager applet.
Make sure that all members of the ESRP group use the same election algorithm. If there is an election
algorithm mismatch between any of the ESRP-enabled switches in any of the ESRP-enabled VLANs in
the ESRP group, this causes a misconfiguration scenario, and ESRP will not function. As a result, none
of the members of the ESRP group will appear in the ESRP Manager applet.
Problem: Some of the switches in an ESRP-enabled VLAN are missing from the ESRP Manager
applet.
Make sure that the Hello Timer (ESRP Timer) is set to the same interval for all ESRP-enabled switches.
If there is a timer mismatch, ESRP will not function correctly, and the ESRP Manager applet will not be
able to detect ESRP switch neighbors that are not being managed by the EPICenter software.
Problem: Devices running ExtremeWare 4.x are not being polled for ESRP information.
The EPICenter server uses Telnet polling to add and update ESRP information for devices running
ExtremeWare 4.x. If you have the “Poll devices using Telnet” option disabled in the Administration
applet, no ESRP information will be obtained for these devices. You can enable telnet polling through
the Server Properties page in the Administration applet. See Chapter 16 for more information.
Inventory Manager
Problem: Discovery returns an error if more than 10,000 IP addresses are specified for a discovery
operation.
Discovering more than 10,000 IP addresses can consume too much memory in the EPICenter server. As
a result, the server does not allow more than 10,000 IP addresses to be discovered at once. If you need
to discover more than 10,000 devices, you must split your discovery into multiple operations.
Problem: Multiple switches have the same name.
This is because the sysName of those switches is the same. Typically, Extreme Networks switches are
shipped with the sysName set to the type of the switch “Summit48,” “Summit1i,” “Alpine3808,” and so
on, depending on the type of switch.
You can change the way names are displayed through a sever property in the Administration applet.
You can display devices in the Component Tree by name or by IP address and name. See Chapter 16 for
more information on setting EPICenter server properties.
