Last Modified: Jan 20, 2023

Bug Tracker

Affected Product:  See more info
F5OS F5OS, Velos(all modules)

Known Affected Versions:
1.5.0, 1.5.1

Opened: Oct 27, 2022
Severity: 3-Major


Traffic on the affected VLAN does not function correctly. Affected tenants are able to respond to ARP requests or other broadcast traffic. Pings may intermittently fail. On an affected F5OS rSeries appliance, even though the VLAN is shared between multiple tenants, the VLAN is missing from the software rebroadcaster, as observed by looking at: docker exec system_tmstat_zmq tmctl -Sd blade rbcast_vlan_stat


Traffic on the affected VLAN does not function correctly. Inbound broadcast traffic is not delivered to tenants.


-- Multiple tenants configured with access to the same VLAN. -- The VLAN is assigned to multiple interfaces, and then removed from one interface.


If a system is already affected, deleting and re-adding the VLAN to an interface or trunk will resolve the issue.
