Displaying And Maintaining Ethernet Link Aggregation; Ethernet Link Aggregation Configuration Examples - HP A5120 EI Series Configuration Manual

CAUTION:

Link-aggregation traffic redirection applies only to dynamic link aggregation groups.

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, disable both MSTP and link-aggregation traffic redirection.

In an IRF fabric that adopts the ring connection, slight packet loss can occur when the IRF member switch
enabled with link-aggregation traffic redirection reboots. To prevent packet loss, you can enable local-first load-
sharing for link aggregation on all IRF member switches (see
aggregation‖).
