Known Affected Versions:

Fixed In:
F5OS v2.0.0
Opened: Dec 09, 2024 Severity: 3-Major
If a VLAN is unassigned from a Tenant and then quickly deleted from the system, an error might be returned from the VLAN deletion: "illegal reference /vlan-listeners/vlan-listener{0.host 1234}/vlan"
The VLAN deletion operation will fail.
A VLAN is deleted from the system immediately after being unassigned from a tenant.
The deletion operation can be retried, or wait a moment after unassigning the VLAN before deleting it.
This fix changes the FDB and Vlan-Listener database schema and api. The Vlan-Listener config mode api has been removed. The Vlan-Listener state table remains as the way to view Vlan-Listener information. An example of the state table is: f5-vlan-listeners:vlan-listeners/vlan-listener=<interface>,<vlan-id>/state The FDB config mode api now only exists to configure Static FDBs. Any FDB created in config mode will be treated as a Static FDB. Non-Static FDBs created by the system will no longer be shown in config mode. Viewing FDB information on the system remains at the same path for Static FDBs. This path is: f5-l2fdb:fdb/mac-table/ Viewing Non-Static FDB information on the system has moved to: f5-l2fdb:fdb/mac-table-l2listeners/
