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 MDS switches (refer to the
Configuration
To suppress the transmission of these SW-RSCNs over an ISL, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# rscn suppress
domain-swrscn vsan 105
You cannot suppress transmission of port address or area address format RSCNs.
Note

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 (like ONLINE or
OFFLINE events). You can use these statistics to monitor responses for each event in the VSAN.
Use the clear rscn statistics command to clear the RSCN statistics for the specified VSAN.
switch# clear rscn statistics vsan 1
After clearing the RSCN statistics, you can view the cleared counters by issuing the show rscn
command.
switch# show rscn statistics vsan 1
Statistics for VSAN: 1
