Enabling link-aggregation traffic redirection

Link-aggregation traffic redirection prevents traffic interruption.
With this feature, when you restart a card that contains Selected ports, traffic can be redirected to other
cards. (In standalone mode.)
With this feature, when you restart an IRF member device or its card that contains Selected ports, traffic
can be redirected to other IRF member devices or other cards. (In IRF mode.)

Configuration restrictions and guidelines

When you enable link-aggregation traffic redirection, follow these restrictions and guidelines:
Link-aggregation traffic redirection applies only to dynamic link aggregation groups and takes
•
effect on only known unicast packets.
• To prevent traffic interruption, enable link-aggregation traffic redirection on devices at both ends of
the aggregate link.
To prevent packet loss that might occur at a reboot, do not enable spanning tree together with
•
link-aggregation traffic redirection.
• Link-aggregation traffic redirection does not operate correctly on an edge aggregate interface.
