Dell 9.7(0.0) manual Lacp fast-switchover

Usage Information

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 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.
