Reference Guide
• Port: Provides 256 addresses for identifying attached N_Ports and NL_Ports.
The following sequence explains the operation for the attached N_Port:
• N_Port sends a Fabric Login (FLOGI) as it requests a unique 24-bit address from the Fabric Login
Server.
• N_Port sends FLOGI to address 0xFFFFFE. Upon success, it obtains a valid address (FCID).
• N_Port sends a Port Login (PLOGI) to inform the Fabric Name Server of its personality and capabilities,
this includes WWNN, WWPN.
• N_Port sends PLOGI to address 0xFFFFFC to register this address with the name server.

Services, the Fibre Channel interfaces are set to shutdown and the fcoe-map default_full_fabric
applies. Any previously configured fcoe-map is removed and you cannot remove the fcoe-map
default_full_fabric from the Fibre Channel interfaces.
Link State Database
The collection of neighbor, connected ports, and cost of all the switches in a Fabric constitutes the link-
state database (LSDB).
Record Headings Description
SwitchName WWN of a switch on the fabric.
PortOut Port number on the local switch that would be used to route a frame to the named
switch.
Hops The number of links between the local switch and the named switch.
Cost The overall link cost (in time) between the local switch and the named switch. Cost
is a function of hops and link speed.
Age Seconds that this route to the switch has existed.
LinkCount Number of ISL records in links array. This value is the number of switches attached
to the named switch.
To view the LSDB information on the S5000 switch, use the show fc lsdb command.
