Verifying the Stack
To verify the stack, perform the following procedure:
1. Start a local management session on any switch in the stack. Refer to
“Starting a Local Management Session” on page 132.
2. From the User Exec mode, enter the SHOW STACK command:
awplus> show stack
An example of the command for a stack of four switches is shown in
Figure 77.
Figure 77. SHOW STACK Command
Review the following items:
 The command should list all the switches. If the list is incomplete,
refer to Chapter 9, “Troubleshooting” on page 179.

The Operational Status field should be “Normal operations” to
indicate that all the stacking ports are operating normally.
 If the Operational Status field is displaying “Not all stack ports are
up,” one or more stacking ports are not being used or cannot
establish links with their counterparts. For more information, refer
to Chapter 9, “Troubleshooting” on page 179.
3. Go to Chapter 8, “Cabling the Networking Ports” on page 167, to
complete the installation.
