Symptoms

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

Impact

MAC masquerading will not function in this environment.

Conditions

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

Workaround

To make Mac Masquerade work with Intel X520 Network Interface Card: -- Virtual functions 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 virtual functions belong to the same PF. -- The driver version must match the following: + driver: ixgbe + version: 5.1.0-k-rh7.5 + firmware-version: 0x80000656

Fix Information

MAC masquerading is now supported when using X520 virtual functions via SR-IOV in Virtual Edition (VE).
