Using Switch Counter Information
Switch counter information can be helpful in supporting troubleshooting the Sun
StorEdge Network Fibre Channel Switch-16. Some general points to keep in mind
when viewing switch counter information are:
■
Quickly increasing counter values or abnormally high counter values may
indicate a problem.
■
A LIP that occurs on one port in a zone propagates to all the ports that have
devices attached to them in the same zone. The LIP counter is incremented on all
those ports.
■
Normal activity can also increase counter values.
■
Counters increment on power cycles.
Note –
Switch Counter data should only be used as supporting data for diagnostics.
Do not use switch counter information as the primary source in the troubleshooting
process.
