Symptoms

The BIG-IP system sends multicast ping from a disabled blade. tmm core

Impact

The BIG-IP system sends unexpected multicast ping requests from a disabled blade.

Conditions

-- There is one or more blades disabled on the VIPRION platform. -- VLAN failsafe is enabled on one or more VLANs. -- the VLAN failsafe-action is set to 'failover'. -- There is more than one blade installed in the chassis or vCMP guest.

Workaround

To mitigate this issue, restart tmm on the disabled blade. This causes tmm to stop sending the multicast traffic. Impact of workaround: Traffic disrupted while tmm restarts.

Fix Information

None
