Usage Information
You can congure the optimal switchover functionality for LACP even if you do not enable the fast boot mode on
the system. You must congure 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 eect
If you congure the optimized booting-time capability and perform a reload of the system, the LACP application
sends PDUs across all the active LACP links immediately.
