8.3.2 VMAC for an Embedded EFN324
The VMAC address that the system allocates to each End-user is based on
the End-user port number, VMAC address node ID and EFN324 identity.

Parameters:
Domain value is 61 (111101 in binary) for an embedded EFN324.
10 indicates that the MAC address is a locally administered unicast
address.
Index is the incrementing number per allocated VMAC address. A
maximum of 256 virtual MAC addresses are allowed per port (range 0 to
255).
Network ID is a number uniquely identifying the network element forming
the virtual MAC address in the access network. It is generated
automatically by PEM, taking the next free number (range 0 to 8191). The
Network ID is configured in the EFN324 by the EMP when the EFN324 is
discovered.
VMAC address node ID is a single integer value (range 16 to 8160, in
steps of 16). The VMAC address node ID is configured in the EFN324 by
the EMP when the EFN is discovered. To configure this value, the EMP
uses the 8-bit embedded EFN Switch ID, followed by five zeros.
End-user port is the physical port on the EFN324 to which the End-user is
connected (range 1 to 26).
Configuration of Virtual MAC for an Embedded Node
Set eda_vmac_format to yes.
Set ‘switching_rule’ to ‘virtual_mac’ in ‘vlan’. Also, set an ‘uplink’ and optionally
a ‘gateway’.
