Usage Guidelines Before changing the timeout value, you must enable RSCN configuration distribution using the rscn
distribute command.
The RSCN timer is registered with Cisco Fabric Services (CFS) during initialization and switchover. For
high availability, if the RSCN timer distribution crashes and restarts or a switchover occurs, it resumes
normal functionality from the state prior to the crash or switchover.
You can determine configuration compatibility when downgrading to an earlier Cisco MDS SAN-OS
Note
release using the show incompatibility system command. You must disable RSCN timer distribution
support before downgrading to an earlier release.
