The following table describes the nonconfigurable data that is displayed.

A stackable switch is a switch that is fully functional operating as a stand-alone unit but can 

also be set-up to operate together with up to seven other switches. This group of switches 
shows the characteristics of a single switch while having the port capacity of the sum of the 
combined switches. 

One of the switches in the stack controls the operation of the stack. This switch is called the 
stack master. The remaining switches in the stack are stack members. The stack members 
use stacking technology to behave and work together as a unified system. Layer 2 and higher 
protocols present the entire switch stack as a single entity to the network.

The stack master is the single point of stack-wide management. From the stack master, you 
configure the following:
