Managing FLOGI, Name Server, FDMI, and RSCN Databases
The RSCN timer value must be the same on all switches in the VSAN.
Note
Before performing a downgrade, make sure that you revert the RSCN timer value in your network to the
Note
default value. Failure to do so will disable the links across your VSANs and other devices.
You can configure the RSCN timer.
