Stacking
Stacking allows users to physically connect up to eight individual Summit
®
switches together as a single
logical unit. This logical unit behaves as a single switch with a single IP address and a single point of
authentication.
The stack is controlled by a master switch. There can only be one stack master in a stack of switches. The
remaining switches in the stack are considered to be stack members.
