The range is 0 to 2000. Specifies a VSAN where the RSCN event timer should be used. The ID of the VSAN is from 1 to 4093. Defaults The default timeout values are 2000 milliseconds for Fibre Channel VSANs and 1000 milliseconds for FICON VSANs. Command Modes Configuration mode. Command History Release 3.0(1) Modification This command was introduced. 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. Note You can determine configuration compatibility when downgrading to an earlier Cisco MDS SAN-OS release using the show incompatibility system command. You must disable RSCN timer distribution support before downgrading to an earlier release. Examples The following example configures an RSCN event timeout value on VSAN 1. switch# config terminal Enter configuration commands, one per line. End with CNTL/Z. switch(config)# rscn event-tov 20 vsan 1 Successful. Commit should follow for command to take effect. 20-42 Cisco MDS 9000 Family Command Reference OL-18089-01, Cisco MDS NX-OS Release 4.x
