Symptoms

A BIG-IP tenant running on a VELOS system incorrectly reports all "ha-only" trunk objects as up, regardless of the actual status of the trunk. BIG-IP tenants can also report incorrect status of trunks after the LAG type is changed from LACP to STATIC or vice-versa. As a result of these, high availability (HA) group failover based on trunk status is unreliable and unusable.

Impact

HA group failover based on trunk status is unreliable and unusable for BIG-IP tenants running on an F5OS system.

Conditions

-- LAGs configured on F5OS system. -- Attempting to use high availability (HA) group failover based on trunk status inside BIG-IP tenant.

Workaround

After configuring a new LAG in the the F5OS partition or changing a LAG type from LACP to STATIC or from STATIC to LACP, reboot the traffic blades. For rSeries devices, the entire device must be restarted. After rebooting, the ha-group trunk entries should show the expected values when one or more members are missing from the aggregate link.
