OmniSwitch 6450 Stack Overview
Users can configure 24- and 48-port OmniSwitch 6450 switches into a single virtual chassis known as a
stack. With stacks, switching capacity can be easily expanded simply by adding additional switches to the
stack. For example, a user can start with a stack composed of two switches and add additional switches to
that stack as network demands increase over time.
Note. Switches should be added one at a time in a stack.
Stacks also provide enhanced resiliency and redundancy features. If a switch in a stack goes down or is
taken offline, the other elements in the stack will continue to operate without disruption. In addition, when
a switch auto-synchronizes at boot-up, or if the user manually synchronize the switches (see
ing Switches in a Stack" on page 6-37
eters are backed up on all switches in the stack. As a result, the original operating software and
configuration parameters can be easily recovered if corrupted or otherwise lost.
Note. In the user guides provided with your OmniSwitch 6450 switch, the terms stack and virtual chassis
are interchangeable referring to OmniSwitch 6450 switches in a stacked configuration. The terms module,
switch, slot, and element are used to refer to individual switches within a stacked configuration. The terms
Chassis Management Module (CMM) and management module refer to those switches operating in a stack
either in the primary or secondary management roles. OmniSwitch 6450 switches operating in an idle role
are essentially acting as network interface modules and therefore may be referred to as Network Interfaces
(NIs).
