Bug ID 1184529: Intermittent ingress broadcast traffic failure for tenants on shared VLAN

Last Modified: Mar 30, 2024

Affected Product(s):
F5OS F5OS, Velos(all modules)

Known Affected Versions:
F5OS-A 1.1.1, F5OS-A 1.3.0, F5OS-A 1.3.1, F5OS-A 1.3.2, F5OS-C 1.3.2, F5OS-C 1.5.0, F5OS-C 1.5.1

Fixed In:
F5OS-C 1.6.0, F5OS-A 1.4.0

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, remove the VLAN from the interface or trunk, and then re-add it.
