Useful CLI Commands
Some problems can be solved by resetting the switching module. Use the hw-module module <n> reset
command to reset a switching module, or remove and re-insert the switching module, which resets,
restarts, and power cycles the switching module. The show module and show diagnostics online
module commands can also provide information useful in solving problems with ports on individual
modules.
Not all software versions support all switching modules. If you are having trouble with a module, refer
to the software release notes to be sure that it is supported by your software.
