Enabling and Disabling Fast Convergence

You can enable or disable fast convergence for the entire switch to improve EAPS (Extreme Automatic Protection Switching) convergence times.

Note

Possible factors affecting EAPS fast convergence time:

The medium type of the link being flapped (Fiber link-down events are detected faster than copper, causing better convergence).
Number of VLANs protected by the EAPS domain (convergence time increases with the number of protected VLANs).
Number of FDB (forwarding database) entries present during the switch over (convergence time increases with the number of FDBs learned).
Topology change event (link down or link up) causes the master node to send an FDB flush to all transits. In the event ofa shared port failure, FDB is flushed twice, causing an increase in convergence time.
Number of hops between the switch where the link flap happens and the master node (convergence increases with the number of hops).

To enable or disable fast convergence on the switch, use the following command:

configure eaps fast-convergence[off | on]
