Symptoms

MAC masquerading is not supported when using X520 virtual functions (VFs) via SR-IOV in Virtual Edition (VE). This is due to a lack of functionality in the underlying hardware.

Impact

MAC masquerading does not function in this environment.

Conditions

-- Use SR-IOV VFs as interfaces within VE. -- Configure MAC masquerading with a shared MAC that should follow the active system after traffic group failovers.

Workaround

None.

Fix Information

MAC masquerading is now supported when using X520 VFs via SR-IOV in VE with following prerequisites: -- VFs must have MAC addresses before deploying the BIG-IP system. -- Trust mode must be set on the host. -- The DB variable, tm.macmasqaddr_per_vlan must be set to true if VFs belong to the same PF. -- The driver version must match the following: + Driver: ixgbe + Version: 5.1.0-k-rh7.5 + Firmware-version: 0x80000656
