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

This example shows how to display the name server database for all VSANs:
switch# show fcns database
--------------------------------------------------------------------------
FCID
--------------------------------------------------------------------------
0x010000
0x010001
0x010002
0x010100
0x020000
0x020100
0x020200
This 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
--------------------------------------------------------------------------
0x030001
0x030101
0x030200
0xec0001
Total number of entries = 4
This example shows how to display the name server database details for all VSANs:
switch# show fcns database detail
This example shows how to display the name server database statistics for all VSANs:
switch# show fcns statistics
FDMI
Cisco SAN 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:
