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 150.
2. From the User Exec mode, type the SHOW STACK command:
The following example is from a stack of three switches:
Consider the following:
The command should list all switches in the stack. If the list is
incomplete, refer to Chapter 11, “Troubleshooting” on page 239.
The Operational Status field should be “Normal operations” to
indicate that all of 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 11, “Troubleshooting” on page 239.
The priority values will be 128, the default value, if you did not
change them.
There is no relationship between the ID numbers and the selection
of the master switch. Consequently, the active master in the
SHOW STACK command might not have the ID number 1.
3. Do one of the following:
If you want to add more SFP+ ports to the trunk, perform “Adding
Ports 25 and 26 on GS980MX/28 or GS980MX/28PSm Switches to
the Stack Trunk” on page 154 or perform “Adding Ports 49 and 50
on GS980MX/52 or GS980MX/52PSm Switches to the Stack
Trunk” on page 156.
If you want to change the priority values of the switches, go to
“STACK PRIORITY” on page 165. The procedure is optional.
Otherwise, go to Chapter 10, “Cabling the Networking Ports” on
page 231 to complete the installation.
