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.
