Common Problems with Port Interfaces
Step 4
Use the
no shutdown
command on the Fibre Channel interface.
switch(config-if)#
no shutdown
By shutting down the interface and bringing it back up, you can determine what happens when the
connected device tries to log in to the interface.
Use the
show flogi internal event-history interface
command to view the events that occurred on the
interface after you enabled it again. The comments that follow each section of output explain the
meaning of the output.
Note
To issue commands with the
internal
keyword, you must have an account that is a member of
the network-admin group.
