Sample source MAC address

Sample destination MAC address

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).
