F5OS F5OS, F5OS-A
Known Affected Versions:
F5OS-A 1.8.0, F5OS-A 1.8.3
Opened: May 17, 2024 Severity: 2-Critical
You can tag the same VLAN to multiple interfaces on r2K/r4K platforms, but when you attach VLANs to interfaces before deploying the tenant, the VLAN members will not be populated in the tenant. On BIG-IP, running 'tmsh list net vlan' will not show any tagged VLANs from F5OS.
The BIG-IP tenant will not show the expected VLANs.
-- rSeries r2K/r4K series platforms -- Tagged VLAN spanning multiple interfaces -- VLANs attached to the interfaces before deploying a BIG-IP tenant
In F5OS, remove and re-attach the vlans to the interfaces. Example: appliance-1(config)# no interfaces interface 1.0 ethernet switched-vlan config appliance-1(config)# no interfaces interface 7.0 ethernet switched-vlan config appliance-1(config)# commit Commit complete. appliance-1(config)# interfaces interface 1.0 ethernet switched-vlan config trunk-vlans [ 1001 3006 ] appliance-1(config-interface-1.0)# interfaces interface 7.0 ethernet switched-vlan config trunk-vlans [ 1001 3006 ] appliance-1(config-interface-8.0)# commit Commit complete. appliance-1(config-interface-8.0)#
