Usage Information

You can configure the optimal switchover functionality for LACP even if you do not enable the fast boot mode on the system. You must configure the long timeout mechanism for the LACP session to enable the fast boot capability to operate properly. This command applies to dynamic port-channel interfaces only. When applied on a static port-channel, this command has no effect

If you configure the optimized booting-time capability and perform a reload of the system, the LACP application sends PDUs across all the active LACP links immediately.
