Usage Guidelines
When a port from a hot-standby state moves to a bundled state, the default time is two seconds. Enabling
fast switchover on the port channel changes this time to 50 ms. This faster time allows the port to quickly
transition to the bundled state, and the port channel continues to stay up.
For information about configuring LACP on physical ports, see the "Configuring EtherChannels"
chapter in the software configuration guide for this release.
Examples
This example shows how to enable fast switchover on port channel 10:
Switch(config)# interface port-channel 10
Switch(config-if)# lacp fast-switchover
