All the switches running 6.2(7) and above are capable of processing coalesced SW-RSCN by default, but they
are capable of sending coalesced SW-RSCN only after enabling through CLI.
Note
Disabling Coalesced SW-RSCNs
To disable the coalesced SW-RSCNs, follow these steps:
Step 1 switch# config terminal
Enters configuration mode.
Step 2 switch(config)# no rscn coalesce swrscn vsan 1
switch(config)#
Disables coalescing of Switch Registered State Change Notification (SWRSCN) in VSAN 1.
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.
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
