Usage guidelines
With this feature, when you restart a card that contains Selected ports, traffic can be redirected to other
cards. Zero packet loss is guaranteed for known unicast traffic, but not for unknown unicast traffic. (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. Zero packet loss is guaranteed for known
unicast traffic, but not for unknown unicast traffic. (In IRF mode.)
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.
Do not enable both spanning tree and link-aggregation traffic redirection at the same time, because light
packet loss may occur when a card or the device reboots.
