Verifying a Stack Configuration
show stack
or
show stack detail commands. If the stack is configured properly, you should see the following:
- One active controller, one standby controller, and stack members
- All stack members with a status of Ready
The following output shows a sample configuration of a stack.

The output from the
show stack command contains a visual diagram of the stack. In the following example, the dashed
line between ports 1/2/1 and 2/2/4 indicates that this stack is configured in a ring
topology. The double dashed lines (equal signs) between all units indicate stack trunk
connections. If a single dashed line were present, it would indicate a connection
through a single stacking port.

|-------------------------------------|
If the link between ports 1/2/1 and 3/2/1 is lost, the stack topology changes to linear, and the diagram changes to resemble the following diagram.

For more detailed information, you can enter the
show stack detail command. The following example shows detailed information for a three-unit stack
connected in a ring topology. Two of the units are connected by stack trunks.

To check the software version installed on each stack unit, enter the
show version command. The software versions should match. If they do not match, refer to "Stack
mismatches."
