Symptoms

Traffic does not pass for newly added tagged VLANs.

Impact

The BIG-IP system does not send/receive traffic for tagged VLANs.

Conditions

1. Native IXLV devices (Intel X710/XL710/XXV710 family) NICs are in use. 2. Tagged VLAN in use. 3. TMM is restarted several times. 4. A new tagged VLAN is added.

Workaround

To work around this, do the following: 1. Stop the BIG-IP guest. 2. Re-load the i40e driver on the hypervisor host using the following command: rmmod i40e; modprobe i40e. 3. Start the BIG-IP guest.

Fix Information

Tagged VLANs now pass traffic as expected regardless of tmm restarts.
