MAC Offset address for Port 6
Bit [31:28]
MAC Offset address for Port 7
Usage:
There are three ways to assign the MAC address to each port. All ports in the same device share the 44
MSBs, MAC[47:4] in ADAR[0:1], while the 4 LSBs, MAC Offset [3:0] can be assigned as follows:
1.
In a managed system, if the device does not support port trunking, MAC_Offset[3:0]= the port number.
2.
In a managed system where device supports port trunking, the ports in the same trunk group shares the same
MAC[3:0]. The value of MAC[3:0] is assigned by the smallest port number in the Trunk Group.
3.
In a managed system, if BIT [18] of DCR2, SMAC=0, all ports are assigned to a single MAC.
4.
In an unmanaged system, MAC[3:0] is fixed for all devices (i.e., only one MAC[3:0] address for the whole
system).
