About Name Server Database Entries
The name server stores name entries for all hosts in the FCNS database. The name server permits an Nx port
to register attributes during a PLOGI (to the name server) to obtain attributes of other hosts. These attributes
are deregistered when the Nx port logs out either explicitly or implicitly.
In a multiswitch fabric configuration, the name server instances running on each switch shares information
in a distributed database. One instance of the name server process runs on each switch.
Displaying Name Server Database Entries
The following example shows how to display the name server database for all VSANs:
switch# show fcns database
--------------------------------------------------------------------------
FCID TYPE PWWN (VENDOR) FC4-TYPE:FEATURE
--------------------------------------------------------------------------
0x010000 N 50:06:0b:00:00:10:a7:80 scsi-fcp fc-gs
0x010001 N 10:00:00:05:30:00:24:63 (Cisco) ipfc
0x010002 N 50:06:04:82:c3:a0:98:52 (Company 1) scsi-fcp 250
0x010100 N 21:00:00:e0:8b:02:99:36 (Company A) scsi-fcp
0x020000 N 21:00:00:e0:8b:08:4b:20 (Company A)
0x020100 N 10:00:00:05:30:00:24:23 (Cisco) ipfc
0x020200 N 21:01:00:e0:8b:22:99:36 (Company A) scsi-fcp
The following example shows how to display the name server database and statistical information for a
specified VSAN:
switch# show fcns database vsan 1
VSAN 1:
--------------------------------------------------------------------------
FCID TYPE PWWN (VENDOR) FC4-TYPE:FEATURE
--------------------------------------------------------------------------
0x030001 N 10:00:00:05:30:00:25:a3 (Cisco) ipfc
0x030101 NL 10:00:00:00:77:99:60:2c (Interphase)
0x030200 N 10:00:00:49:c9:28:c7:01
0xec0001 NL 21:00:00:20:37:a6:be:14 (Seagate) scsi-fcp
Total number of entries = 4
The following example shows how to display the name server database details for all VSANs:
switch# show fcns database detail
The following example shows how to display the name server database statistics for all VSANs:
switch# show fcns statistics
FDMI
Cisco Nexus 5000 Series switches provide support for the Fabric-Device Management Interface (FDMI)
functionality, as described in the FC-GS-4 standard. FDMI enables management of devices such as Fibre
Channel host bus adapters (HBAs) through in-band communications. This addition complements the existing
Fibre Channel name server and management server functions.
Using the FDMI functionality, the switch software can extract the following management information about
attached HBAs and host operating systems without installing proprietary host agents:
• Manufacturer, model, and serial number
• Node name and node symbolic name
• Hardware, driver, and firmware versions
