The egress policy associated with the VM/MAC address. Note that this may refer to a policy without
a corresponding entry in the extremeVMVPPTable if a network policy mapping refers to a non-existent policy.
This would indicate an error in the policy mapping file that is consulted if network authentication fails.
When creating an entry in this table, this name must refer to an existing, valid, local policy. The creation of
a mapping to a network policy is not permitted. Those mappings must be created at the central policy server.
