Stacking of switches

                   What is meant by stacking in switches how to do that.

I  have checked one of my cisco switch it having ports of 104 Port( Gig1/0/1---Gig1/052 and gig 2/0/1 ...... gig2/0/52). i thought it was 104 port switches. But they said it was 52 port switch which was stacked of 2 52 Port switches. Need information regarding this concept ?

In depends.  One older usage of "stacking" switches, often meant to daisy-chain or cascade connect them.  E.g. sw1 <> sw2 <> sw3 <> sw4

If the switches support STP, you might also connect them in a ring, i.e. in the prior example, sw1 would also connect to the last switch, sw4.

The interconnections between such stacked switches was usually on "normal" ports, but Cisco also had for some of their switches "special" stack cables that could be used, e.g. GigaStack - see

In some later Cisco switches, Cisco provided a new "kind" of stack.  Starting with the original 3750/3750G series, Cisco provided StackWise stacking, see

What made StackWise different, the "stacked" devices functioned as one logical device.  Cisco has subsequently provided StackWisePlus (3750E/3750X), FlexStack (2960S), FlexStack-Plus (2960X) (see and StackWise-480 (3850) that also have all the stacked devices function as one logical device.
