Stacking
27.1 Stacking Overview
This chapter introduces switch stacking and discusses how to configure stacking mode on the Switch to
form a switch system.
27.1.1 What You Can Do
• Use the Stacking Status screen ( Section 27.2 on page 200 ) to view the stacking system status and
topology for the Switch.
• Use the Stacking Setup screen ( Section 27.3 on page 203 ) to configure the stacking system.
27.1.2 What you need to know
Stacking is directly connecting Switches to form a larger system that behaves as a single Switch or a
virtual chassis with increased port density.
Figure 134 Switch Stacking Concept
The last four combo ports of your Switch are dedicated for Switch stacking. At the time of writing, the
Switch can only connect to another Switch of the same model and firmware version.
Note: Up to four Switches per stack are allowed.
Note: See Section 1.1.1 on page 31 for the services not supported in stacking mode.
You can manage each Switch in the stack from a master Switch using its Web Configurator or console.
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. Each Switch supports up to two stacking channels. The stacking ports used
to form the same stacking channel must be connected to the ports of the same channel on a
neighboring Switch. For example, ports 25 and 26 (channel 1) on Switch A can connect to ports 25 and
