Enabling link-aggregation traffic redirection
The link-aggregation traffic redirection function can redirect traffic between IRF member switches for
cross-device link aggregation group. Link-aggregation traffic redirection prevents traffic interruption when
you reboot a IRF member switch that contains link aggregation member ports. For more information
about IRF, see IRF Configuration Guide.
Link-aggregation traffic redirection applies only to dynamic link aggregation groups and only to known
unicast packets.
After link-aggregation traffic redirection is enabled, do not add an Ethernet interface configured with
physical state change suppression to an aggregation group. Otherwise, Selected ports in the
aggregation group might work improperly. For more information about physical state change
suppression, see the link-delay command in Ethernet interface configuration commands.
