Displaying Information on Stack Connections
You can check the data connections between stack units with the
show stack connection command.
When the
show stack connection command output includes the message
*** error: one-way, this may indicate a stack port to non-stack-port connection. When this occurs, the
side of the connection that is incorrectly configured as a stack port must be converted
to a data port.
In the following example, the
show stack connection command output indicates that CPU-to-CPU connections are working properly between
all members of the stack.
