Verifying a Stack Configuration

Log in to the active controller and verify the stack information by entering the 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 line (equal signs) between units 1 and 2 indicates a stack trunk connection. Where a single dashed line is present between units, it indicates a connection through a single stacking port.

    active       standby
     +---+        +---+        +---+        +---+
 -2/5| 1 |2/1==2/5| 2 |2/1--2/1| 3 |2/5--2/1| 4 |2/5-
 |   +---+        +---+        +---+        +---+   |
 |                                                  |
 |--------------------------------------------------|                                                    

If the connection between ports 1/2/5 and 4/2/5 is lost, the stack topology changes to linear, and the diagram changes to resemble the following diagram.

    
    active       standby
     +---+        +---+        +---+        +---+
 -2/5| 1 |2/1==2/5| 2 |2/1--2/1| 3 |2/5--2/1| 4 |2/5
     +---+        +---+        +---+        +---+                                                   

For more detailed information, you can enter the show stack detail command. The following example shows detailed information for a twelve-unit stack.
