I'm being asked to provide a comparison between switches and a specifically was asked if the 2960 switch is stackable. It's definitely rackable, but is it stackable?
Stackable switches are:
Layer 2 - 2975
Layer 3 - 3750
Data Sheet Cisco Catalyst 2975 Switch with LAN Base Software
2960 is not stackable.
2950 can use Gigastack GBIC to do stacking.
3750 can use special stacking cable to do stacking.
