Connect a terminal to the console port, and look for any of the following system
messages:
C4K_CHASSIS-3-LINECARDMUXBUFFERTOSUPALIGNMENTWRON
G
C4K_CHASSIS-3-LINECARDNOTVALIDINSLOT
C4K_CHASSIS-3-MODULENOTSUPPORTHALF
C4K_IOSINTF-5-STALEPHYPORT
C4K_IOSMODPORTMAN-4-INLINEPOWEROVERMAX
If you observe any of these messages, follow the suggestion for that message.
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.
