Bug ID 1117609: VLAN guest tagging is not implemented for CX4 and CX5 on ESXi

Last Modified: Dec 13, 2023

Affected Product(s):
BIG-IP TMOS(all modules)

Known Affected Versions:,,, 14.1.5,,,,,,, 16.1.3,,,,,

Fixed In:
17.1.1, 16.1.4, 15.1.10

Opened: Jun 21, 2022

Severity: 3-Major


Tagged VLAN traffic is not received by the BIG-IP Virtual Edition (VE).


Host-side tagging is required.


Mellanox CX4 or CX5 with SR-IOV on VMware ESXi.


If only one VLAN is required, use host-side tagging and set the VLAN to "untagged" in the BIG-IP guest. If multiple VLANs are required, use the "sock" driver instead. Edit the /config/tmm_init.tcl file and restart the Virtual Edition (VE) instance. Network traffic is disrupted while the system restarts. echo "device driver vendor_dev 15b3:1016 sock" >> /config/tmm_init.tcl CPU utilization may increase as a result of switching to the sock driver.
