lacp fast-switchover
Cause the physical ports to be aggregated faster by configuring this capability in a port-channel on both
the nodes that are members of a port-channel.

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.

Optimizing the Boot Time
This functionality is supported on the S6000 platform.
You can configure an optimization technique to reduce the booting time of an S6000 Switch. This
mechanism is also called fast boot. With the reduced time that is taken to reboot the switch, upon a
manually-initiated reload or an expected restart of the device, the disruption in traffic that is serviced by
the switch is minimized. Traffic outage is lowered considerably (reduced to approximately 25 seconds in
certain network deployments) when you enable this optimization method for booting of the device. By
reducing the duration of traffic loss, subscriber sessions are processed and preserved in an effective and
seamless way.
You can configure this capability on an S6000 Switch that is deployed as a top-of-rack (ToR) switch. The
ToR switch is the single point of connection to the network for servers in that rack. This functionality of
minimized reload time is supported in a network deployment in which the servers are connected through
a ToR, leaf and spine unit or configuration setup. An exterior border gateway protocol (EBGP) session
