Troubleshooting an IronStack

Troubleshooting an unsuccessful stack build
If you are unable to build a stack, (for example, the show stack command does not display any
stack units), perform the following steps.
1. Enter the show run command on each unit to make sure the configuration contains “stack
enable”. If it does not, enter the stack enable command on the unit. Before a stack is formed,
you can still access the console port on each device. Once a stack is successfully formed, you
are redirected to the Active Controller.
NOTE
If you are building a stack using secure-setup, you do not have to enter stack enable on each
unit.
2. Check that all of your stacking port connections are secure and working properly. Enter the
show interface stack on each device to confirm that the stacking port links are up and the
ports are in the forward state.

1/2/2 Up Forward Full 10G None No 1 0012.f2eb.a904
3. Confirm that all of the devices are running the same software image
4. Use the show log command to display any IPC version mismatch messages. These messages
appear in one minute when receiving mismatched probe packets, and then once every 10
minutes.
5. Type show stack ipc to see if any traffic has been sent or received. Enter clear stack ipc to clear
the traffic statistics and then enter show stack ipc again so you can easily see differences in
traffic flow.
