Reading Hexadecimal Port Diagrams

Many of the commands return port diagrams in Hexadecimal format. For example:

switch:admin> bcastShow

Group

------------------------------------------------------------

256

To read the hexadecimal port diagrams they must be converted into binary notation. Each

hexadecimal value represents four binary values. Each hexadecimal value is converted into a group

four binary values that represent four ports as follows:

Hex value = Binary value

0 = 0000

1 = 0001

2 = 0010

3 = 0011

4 = 0100

5 = 0101

6 = 0110

7 = 0111

8 = 1000

9 = 1001

A = 1010

B = 1011

C = 1100

D = 1101

E = 1110

F = 1111

Once the hexadecimal is converted into a binary bit map, each bit represents a port, where a value

of 1 means yes and a value of 0 means no. The bit map is read from right to left, that is, the least

significant bit represents port 0.

For example, if the member port value is displayed in hex as:

0x00012083

This corresponds to a binary bit map of the member ports as follows:

0000 0000 0000 0001 0010 0000 1000 0011

This bit map displays the member ports as port 0, 1, 7, 13, and 16. Each switch has a hidden

internal port (in the example above port 16) which is always a member of a broadcast group.
