switch# configuration terminal
switch(config)#
Step 2
switch(config)# rscn multi-pid vsan
vsan-id

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. For additional information, see the Cisco MDS 9000 Family Switch-to-Switch
Interoperability Configuration Guide, available at the following location:
http://www.cisco.com/en/US/docs/storage/san_switches/mds9000/interoperability/guide/intopgd.html
To suppress the transmission of these SW-RSCNs over an ISL, perform this task:
Command
Step 1
switch# configuration terminal
switch(config)#
Step 2
switch(config)# rscn suppress
domain-swrscn vsan vsan-id
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 (such as ONLINE or
OFFLINE events). You can use these statistics to monitor responses for each event in the VSAN.
The following example shows how 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 entering the show rscn
statistics command:
switch# show rscn statistics vsan 1
