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

Last Modified: May 29, 2024

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

Known Affected Versions:
14.1.4.4, 14.1.4.5, 14.1.4.6, 14.1.5, 14.1.5.1, 14.1.5.2, 14.1.5.3, 14.1.5.4, 14.1.5.6, 16.1.2.2, 16.1.3, 16.1.3.1, 16.1.3.2, 16.1.3.3, 16.1.3.4, 16.1.3.5

Fixed In:
17.1.1, 16.1.4, 15.1.10

Opened: Jun 21, 2022

Severity: 3-Major

Symptoms

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

Impact

Host-side tagging is required.

Conditions

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

Workaround

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.

Fix Information

None
