If you are managing the switch over a Telnet connection, enable terminal monitoring by entering the terminal monitor command in exec mode. The system output looks like this: switch# show fcns database detail vsan 99 VSAN:99 FCID:0x780200 port-wwn (vendor) :21:00:00:e0:8b:07:a4:36 (QLogic) /* Port world wide name */ node-wwn :20:00:00:e0:8b:07:a4:36 class :3 /* Fibrechannel class of service */ node-ip-addr :0.0.0.0 /* IP Address */ ipa :ff ff ff ff ff ff ff ff fc4-types:fc4_features:scsi-fcp:init /* Registered FC4 Types: example SCSI and initiator */ symbolic-port-name : symbolic-node-name : port-type :N /* Fibrechannel port type (F,FL) */ port-ip-addr :0.0.0.0 fabric-port-wwn :20:8e:00:05:30:00:86:9e /* wwn of the switch port */ hard-addr :0x000000 Other attribute objects of the Nx port are registered one per register operation after the FLOGI process is complete. The Nx port performs PLOGI to the well-known WWN of the Name Server, 0xFFFFFC. The FC_CT Common Transport protocol uses Request and Accept messages to conduct transactions. To verify that additional attributes are correctly registered and recorded in the database, you can use the SAN-OS debug facility. Note The command show fcns database detail vsan X displays a detailed list of all devices registered in the fabric. 8-20 Cisco MDS 9000 Family Troubleshooting Guide, Release 3.x OL-9285-05
