Configuring Stack Overview

Overview

A stack is a set of multiple stackable devices connected through their stack ports. The

stack works as a unified and high-performance system to the network. Compared to one

single switch, the stack brings higher reliability.

1.1 Stack Membership

There are two roles in a stack.



Master: A stack always has one and only one stack master. The master switch controls

the operation of all switches in the stack.



Member: The member switches refers to all the other switches in the stack except the

master. The member switches provide backup for the master. If the master fails, the

stack will elect a new master from the remaining stack members to replace the previous

master.

1.2 Stack Topology

Stack typically adopts a chain topology or ring topology:



The chain topology is mainly used in a network where switches in the stack are

distributively located.



The ring topology is more reliable than the chain topology. In a chain connected stack,

link failure can cause stack split. While in a ring connected stack, the system is able to

operate normally with a new chain topology when a link failure occurs.
