ICX Stack Troubleshooting

Troubleshooting an unsuccessful stack build

Troubleshooting an unsuccessful stack build

If you are unable to build a stack (for example, the show stack command does not display any members), perform the following
steps.
1. Enter the show running-config 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 stack interactive-setup, you do not have to enter the stack enable command
on each unit.
2. Check that all of your stacking port connections are secure and working properly. Enter show interfaces stack on each
device to confirm that the stacking port links are up and the ports are in the forward state.
device# show interfaces stack
Port Link
1/2/1 Up
1/2/2 Up
NOTE
When you use stack interactive-setup or stack zero-touch provisioning, data ports can be in the BLOCKING state
if Spanning Tree Protocol is configured. However, stack interactive-setup probe packets can traverse blocked
ports.
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.
