show flogi database vsan vsanid
The system output might look like this:
switch# show flogi database vsan 99
---------------------------------------------------------------------------
INTERFACE VSAN FCID PORT NAME NODE NAME
---------------------------------------------------------------------------
fc3/14 99 0x780200 21:00:00:e0:8b:07:a4:36 20:00:00:e0:8b:07:a4:36
If the device in question appears in this output, skip to Step 8. If the device does not appear in the output,
go to the next step.
Step 3 From interface mode, shut down the FC interface connected to the device in question.
config terminal
interface fcx/x
shutdown
Step 4 Enter the following command on the FC interface:
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.
Step 5 Enter the following command to view the events that occurred on the interface after you enabled it again:
switch# show flogi internal event-history interface fc3/14
The system output looks like this:
