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.
