When you have an NPIV core switch that has several downstream NPV edge switches attached, you
might want to locate the exact port that a server is physically attached to.

VSANs stuck in initializing state after configuring the 4.2(1)N1 F_Port trunking
feature
Using the show interface command of the F_Port trunking port channel or trunking member of the port
channel indicates that certain VSANs are in an initializing state and do not come online.

Identify the PWWN of the server and the corresponding switch that it is attached to.
Example:
NPIV-Core(config-if)# show flogi database
fc1/16 100 0xee00e4 21:00:00:04:cf:17:66:b7 20:00:00:04:cf:17:66:b7
fc1/16 100 0xee00e8 21:00:00:04:cf:17:66:0e 20:00:00:04:cf:17:66:0e
fc1/25 100 0xee0100 20:41:00:0d:ec:a3:da:40 20:64:00:0d:ec:a3:da:41
fc1/26 100 0xee0200 20:42:00:0d:ec:a3:da:40 20:64:00:0d:ec:a3:da:41
fc1/26 100 0xee0201 21:00:00:c0:dd:12:04:f3 20:00:00:c0:dd:12:04:f3
In the example, the server is identified by this address:
fc1/26 100 0xee0201 21:00:00:c0:dd:12:04:f3 20:00:00:c0:dd:12:04:f3
and the switch is identified by this address
fc1/26 100 0xee0200 20:42:00:0d:ec:a3:da:40 20:64:00:0d:ec:a3:da:41
Identify the IP address of the NPV edge switch.
Example:
NPIV-Core(config-if)# sh fcns database npv
VSAN 100:
20:64:00:0d:ec:a3:da:41 172.18.217.51 fc2/1 20:00:00:0d:ec:51:0c:00 fc1/25
20:64:00:0d:ec:a3:da:41 172.18.217.51 fc2/2 20:00:00:0d:ec:51:0c:00 fc1/26
Telnet to the NPV edge switch.
Example:
NPIV-Core(config-if)# telnet 172.18.217.51
Identify the PWWN of the server.
Example:
switch-NPV-Edge# show npv flogi-table
vfc3 100 0xee0201 21:00:00:c0:dd:12:04:f3 20:00:00:c0:dd:12:04:f3 fc2/2
If the interface is a FCoE (VFC) interface as shown in the previous example, use the show interface
vfc3 command to see which port that the VFC is physically bound to.
