Hello,

If I understand your question correctly I believe the command fabricshow should hold all the information you require.

Kindly find below an example of the output presented by fabricshow:

switch:admin>

fabricshow
Switch      ID           Worldwide Name                Enet IP Addr        FC IP Addr           Name

-------------------------------------------------------------------------

65:           fffc41      10:00:00:60:69:00:02:0b      192.168.64.180     192.168.65.180 > "sw180"

Please let me know if this answers your question.

Have a great day.
