Enabling link-aggregation traffic redirection
IMPORTANT:
In Release 1111, this feature is supported only in system view. In Release 1121 and later, this
feature is supported in system view, Layer 2 aggregate interface view.
Link-aggregation traffic redirection prevents traffic interruption.
When you shut down a Selected port in an aggregation group, this feature redirects traffic to other
Selected ports.
When you restart an IRF member device that contains Selected ports, this feature redirects traffic to
other IRF member devices.
You can enable link-aggregation traffic redirection globally or for an aggregation group. Global
link-aggregation traffic redirection settings take effect on all aggregation groups. A link aggregation
group preferentially uses the group-specific link-aggregation traffic redirection settings. If
group-specific link-aggregation traffic redirection is not configured, the group uses the global
link-aggregation traffic redirection settings.
Configuration restrictions and guidelines
When you enable ink-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.
•
As a best practice, enable link-aggregation traffic redirection on aggregate interfaces. If you
enable this feature globally, communication with a third-party peer device might be affected if
the peer is not compatible with this feature.
