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. 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.

The following example shows how to set the OpenFlow purge timer: 

device(config)# openflow purge-time 500
device(config)# no openflow purge-time 350

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