Feb 17 04:42:55 fcns: vsan 99: Registered fc4-types for port-id 780200
Feb 17 04:42:55 fcns: vsan 99: Registered fc4-features for fc4_type 8 for port-id 780200
/* FC4 Type, type 8 FCP has been registered */
Additional lines similar to these will be listed if more name server objects are registered.
Step 7 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

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.
