Setting the OpenFlow Purge Timer

You can configure the maximum time before stale flows are purged from the OpenFlow flow table after a switchover, failover, or operating system upgrade.

The valid range is from 1 through 600 seconds. The default is 240 seconds.

You may not need to change the value of the OpenFlow purge timer under normal circumstances. If you anticipate a delay in learning the flows from the controller after switchover, you can configure a larger value for the OpenFlow purge timer.

To set the OpenFlow purge timer, enter the openflow purge-time command.

device(config)# openflow purge-time 500

The no form of this command sets the purge timer time to its default value.
