EXEC mode.

This command was introduced in Cisco MDS SAN-OS Release 1.0(2).

Output of this command is first sorted on interface and then on VSANs.

In a Fibre Channel fabric, each host or disk requires an FC ID. Use the show flogi database command to verify if a storage device is displayed in the Fabric login (FLOGI) table as in the examples below. If the required device is displayed in the FLOGI table, the fabric login is successful. Examine the FLOGI database on a switch that is directly connected to the host HBA and connected ports.

Examples

The follwing example displays details on the FLOGI database.

 

switch# show flogi database
