show fspf

To display global Fibre Shortest Path First (FSPF) routing information, use the show fspf command.

show fspf [ database [ vsan vsan-id ] [ detail | domain domain-id detail ] | interface | vsan vsan-id interface { fc slot / port | san-port-channel port-channel }]

Syntax Description

vsan vsan-id
(Optional) Specifies the Virtual SAN (VSAN) ID. The range is from 1 to 4093.
(Optional) Displays detailed FSPF information.
domain domain-id
(Optional) Specifies the domain of the database. The range is from 0 to 255.
(Optional) Specifies the FSPF interface.
fc slot / port
