Ahmed,
This numbering scheme is primarly used for switches that can be stacked together. You can stack to physical switches together to make logical switches. Example:-
If you have 1 x 48 port switch, you see ports 1 to 48 as:-
1/0/1 - 1/0/48
If you add another 48 port switch - as it's the second of the stack you would see ports 1 to 96 as:-
Switch 1 - stack member 1
1/0/1 - 1/0/48
Switch 2 - stack member 2
2/0/1 - 2/0/48
You still have 2 physical switches, and 96 switch ports, but logicall in the config you see 1 switch and 2 x 48 ports. If you added a third switch:-
Switch 3 - stack member 3
3/0/1 - 3/0/48
all the way up to 9 switches in a stack.

Hi
I think by default u r switch will be the member switch with member number 1.So due to this it might have this interface indentification scheme.
Thanks
