Figure 65. SHOW STACK Command
Here are a couple items to consider:
 The command should list all the switches in the stack. If the list is
incomplete, refer to Chapter 9, "Troubleshooting" on page 179.

The Operational Status field displays "Normal operations" when
the switches are connected in the ring topology and "Not all stack
ports are up" when the switches are connected in the linear
topology.
 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 change the priority values of the switches, go to
"Setting the Priority Numbers" on page 135. The procedure is
optional.
