Hi


When you talk about stacking the cisco switches, there are two techniques


gigastack :- In this you connect all the switches uplink with gigabit stack GBIC.

guru prasad has given one cisco url for that.


and all the switches that support stackwise technology are now end of sale.


stackwise and stackwise plus :-

Cisco StackWise technology unites up to nine individual Cisco Catalyst 3750 switches into a single logical unit, using special stack interconnect cables and stacking software. The stack behaves as a single switching unit that is managed by a master switch elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption.

now we can say that we have only one stacking option available that is of stackwise as all model which supported gigstack are now end os sale.
