Understanding Switch Stacks
A switch stack is a set of up to four Ethernet switches connected through their stacking ports. One of
the switches controls the operation of the stack and is called the stack manager. All other 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 Layer 3 protocols present the entire switch stack as a single entity to
the network.
The stack manager is the single point of stack-wide management. From the stack manager, you
configure:
•
System-level (global) features that apply to all stack members
•
Interface-level features for all interfaces on any stack member
A switch stack is identified in the network by its network IP address. The network IP address is assigned
according to the MAC address of the stack manager. The MAC address used by the switch is the MAC
