Symptoms

Prior to F5OS-A 1.4.0, r2xxx/r4xxx each BIG-IP tenant network interface uses the same MAC address.

Impact

Cases like inline L2 require MAC Data/MAC Block Size to be greater than one.

Conditions

For cases like inline L2, tenants require each BIG-IP tenant interface to have a unique MAC address.

Workaround

Upgrade to 1.4.

Fix Information

When deploying a tenant, selecting MAC Data/MAC Block Size value of small represents a block of 8 MACs. When this value is used, the tenant gets a block of 8 contiguous MACs. When using LAGs, tenants require that trust-mode is set to true in order to adjust tenant interface MAC addresses.
