Problems commonly diagnosed with stack
formation
The most common reason for an unsuccessful stack build is a hardware configuration mismatch, a software configuration
mismatch, or a combination of both.
The following common problems may be encountered when building stacks:
• Ports on the same trunk connect to different units.
• Ports on the same trunk connect to different trunks on the same unit.
• Sub-ports of the 4 x 10-Gbps module are down.
• One end of a 10-Gbps port is up, but the other end is down.
• Communication problems exist between units in the stack.
A common connection error is that the two cables of a trunk go to different units or to different trunks on the same unit. A stack
may still form in these cases, but the incorrect connection may cause an internal forwarding loop, or the unit may have
forwarding problems.

Manually triggering stack diagnosis

You can manually trigger stack diagnosis using the show stack connection command. This command can provide additional
detail on connections that are identified as problems.
