Usage Guidelines
In addition to the system health checker, you can scan the FDB on a stand-alone switch, or on a per slot
or backplane basis on a modular switch. This setting is independent of and does not affect the system
health check configurations.
To determine if you have FDB scanning enabled and the failure action the switch takes, use the
show
switch
command. The following is sample FDB scanning output:
Fdb-Scan Diag: Enabled. Failure action: log only
For ExtremeWare 6.2.2b108:
The default for the FDB scan is enabled.
For ExtremeWare 6.2.2b134 and ExtremeWare 7.1.0:
The default for the FDB scan is disabled. If you load your saved ExtremeWare 6.2.2b108 configurations
onto a switch with ExtremeWare 6.2.2b134 or ExtremeWare 7.1.0 or later, FDB scanning is enabled. You
must manually disable FDB scanning if you want the feature disabled.
