Verifying the RSCN Timer Configuration

You verify the RSCN timer configuration using the show rscn event-tov vsan command. This example shows
how to clear the RSCN statistics for VSAN 10:
switch# show rscn event-tov vsan 10
Event TOV : 1000 ms

RSCN Timer Configuration Distribution

Because the timeout value for each switch is configured manually, a misconfiguration occurs when different
switches time out at different times. Different N-ports in a network can receive RSCNs at different times.
Cisco Fabric Services (CFS) infrastructure alleviates this situation by automatically distributing the RSCN
timer configuration information to all switches in a fabric, which also reduces the number of SW-RSCNs.
RSCN supports two modes, distributed and nondistributed. In distributed mode, RSCN uses Cisco Fabric
Services (CFS) to distribute configuration to all switches in the fabric. In nondistributed mode, only the
configuration commands on the local switch are affected.

Managing FLOGI, Name Server, FDMI, and RSCN Databases
Purpose
Enters global configuration mode.
Enables RSCN timer configuration distribution.
Sets the event time-out value in milliseconds for
the specified VSAN. The range is 0 to 2000
milliseconds. Setting a zero (0) value disables
the timer.
Reverts to the default value (2000 milliseconds
for Fibre Channel VSANs).
Commits the RSCN timer configuration to be
distributed to the switches in the specified
VSAN.
