Last Byte

The byte is in hexadecimal format, the chart below shows the binary value and the bit numbers:

	Byte =	Bit Data
Bit Number:		7 6 5 4 3 2 1 0
Last byte of source MAC address (SA)	48	0 1 0 0 1 0 0 0
Last byte of destination MAC address (DA)	51	0 1 0 1 0 0 0 1

The mapping rule is described below:

1.The two bits selected by the user for mapping will result in an odd or even value assignment.

		Exclusive Or (XOR) Values
Bit 1	Bit 2	Bits Selected	Value
0	0	0 XOR 0	= 0	[Even]
0	1	0 XOR 1	= 1	[Odd]
1	0	1 XOR 0	= 1	[Odd]
1	1	1 XOR 1	= 0	[Even]

2. Four combinations of the result are mapped to four trunk ports:

Source Address	Destination Address	Trunk Port
Odd	Odd	Trunk Port 1
Odd	Even	Trunk Port 2
Even	Odd	Trunk Port 3
Even	Even	Trunk Port 4

For example, if the user species bit 1 and 0 for mapping and Trunk 2 is assigned, the packets would be sent to the third Trunk Port of Trunk 2 (which would be Port 7).
