Device login issues

In some cases, you may find that the port has been locked as an L_Port and the device
attached is a fabric point-to-point device such as a host or switch. This would be an incorrect
configuration for the device and therefore the device cannot log into the switch.
To correct this type of problem, remove the Lock L_Port configuration using the portCfgDefault
command.

steadily increasing number of errors can indicate a problem. Track errors by sampling the port
errors every five or ten minutes until you see the problem occur again.
5. Enter the portFlagsShow command; then, check to see how a port has logged in and where a
login failed (if a failure occurred):
