Sample source MAC address

Sample destination MAC address

00:C0:F0:1C:23:48

00:C0:F0:22:32:51

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).
