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.
