Chapter 27 Stacking
XGS2220 Series User’s Guide

In stacking mode, the stacking channel is using link-aggregation. The default algorithm type is src-dst-
mac, and is not configurable.
You can build a Switch stack using a ring or chain topology. In a ring topology, the last Switch is
connected to the first.
Figure 149 Stacking Topology
Use the master Switch to assign a ‘slot ID’ for each ‘linecard’ non-master Switch. ‘Slot’ refers to a Switch
in the ‘virtual chassis’ stack.
The advantages of stacking are:
• High port density – for example, two 24-port Switches can become one 48-port logical Switch
• Centralized management – log into a single IP address of the master switch to control all Switches in
the stacking system using the Web Configurator, CLI, SNMP or FTP
• Redundancy – Data redundancy allows traffic to be forwarded even if one Switch in the stack fails.
Management redundancy lets you still manage the stack even if one Switch in the stack fails
• Modularity and hot-swappable – you can add, remove, or replace Switches to increase or decrease
the stack with minimum disruption to ongoing network traffic.
