Other devices in the network will see the VSS configured switches as a single switch, which allows the engineer the ability to create multi chassis Ether-Channels between the VSS pair and other devices while appearing to other protocols like spanning-tree as a single switch.
Cisco switch stacks are an affordable alternative to the more expensive Cisco Catalyst 4500 and 6500 modular switching chassis. The cisco switch stack provides single point of management, redundancy and is easily expanded to provide to additional port density. What is a switch stack?
