rscn event-tov

To configure an event timeout value for a Registered State Change Notification (RSCN) on a specified

VSAN, use the rscn event-tov command in configuration mode. To cancel the event timeout value and

restore the default value, use the no form of the command.

Syntax Description

The default timeout values are 2000 milliseconds for Fibre Channel VSANs and 1000 milliseconds for

FICON VSANs.

Command Modes

Configuration mode.

Command History

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

release using the show incompatibility system command. You must disable RSCN timer distribution

support before downgrading to an earlier release.

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.
