Etherchannel - fast-switchover
This command will essentially result in sub-second failover delay for an EtherChannel link when activated.
Prior to entering the
lacp fast-switchover command, you must ensure the following:
- The port channel protocol type is LACP.
lacp max-bundle 1command has been entered on the port channel.
Note that the recommended setup is to configure only two ports in such a bundle, where one will act as active, and one as hot-standby for optimum performance.
This is why the
lacp max-bundle 1 command is recommended. For more info on this command, take a look at EtherChannel - max-bundle.
