Useful Commands at the FC-MAC Level

Troubleshooting a port problem involves analysis of the debug facilities provided by the FC-MAC driver,
or the FC-MAC2 driver in the case of the MDS 9120, MDS 9140, MDS 9216i, and the MPS-14/2
module.
Note You must use the attach module CLI command to access these FC-MAC show commands.
