Section 7. Managing Stacking
Stacking provides multiple switch management through a single point as if all stack members are a single unit. All
stack members are accessed through a single IP address through which the stack is managed. The stack is can
be managed from the following:
• Web-based Interface
• SNMP Management Station
• Command Line Interface (CLI)
Devices support stacking up to eight units per stack, or can operate as stand-alone units.
During the Stacking setup, one switch is selected as the Stacking Master and another stacking member can be
selected as the Secondary Master. All other devices are selected as stack members, and assigned a unique Unit
ID.
Switch software is downloaded separately for each stack members. However, all units in the stack must be run-
ning the same software version.
Switch stacking and configuration is maintained by the Stacking Master. The Stacking Master detects and recon-
figures the ports with minimal operational impact in the event of:
• Unit Failure
• Inter-unit Stacking Link Failure
• Unit Insertion
• Removing a Stacking Unit
This section provides an introduction to the user interface, and includes the following topics:
• Understanding the Stack Topology
• Stacking Failover Topology
• Exchanging Stacking Members
• Switching the Stacking Master
• Configuring Stacking
