Suppressing Domain Format SW-RSCNs

A domain format SW-RSCN is sent whenever the local switch name or the local switch management IP
address changes. This SW-RSCN is sent to all other domains and switches over the ISLs. The remote switches
can issue GMAL and GIELN commands to the switch that initiated the domain format SW-RSCN to determine
what changed. Domain format SW-RSCNs can cause problems with some non-Cisco SAN switches.
To suppress the transmission of these SW-RSCNs over an ISL, perform this task:

Clearing RSCN Statistics

You can clear the counters and later view the counters for a different set of events. For example, you can keep
track of how many RSCNs or SW-RSCNs are generated on a particular event (such as ONLINE or OFFLINE
events). You can use these statistics to monitor responses for each event in the VSAN.
