Function

The display isis lsdb command displays information about IS-IS LSDBs.

Format

display isis process-id lsdb [ { level-1 | level-2 } | verbose | { local | lsp-id | is-name symbolic-name } ] ^*

display isis lsdb [ { level-1 | level-2 } | verbose | { local | lsp-id | is-name symbolic-name } ] ^* [ process-id | vpn-instance vpn-instance-name ]

Parameters

Parameter	Description	Value
process-id	Specifies an IS-IS process ID.	The value is an integer that ranges from 1 to 65535.
level-1	Displays Level-1 LSDBs. If no level is specified, Level-1 and Level-2 LSDBs are displayed.	-
level-2	Displays Level-2 LSDBs. If no level is specified, Level-1 and Level-2 LSDBs are displayed.	-
verbose	Displays detailed information about IS-IS LSDBs.	-
local	Displays information about the local LSDB.	-
lsp-id	Specifies an LSP ID.	The value is in dotted decimal notation. The value ranges from 16 to 20 in ####.####.####.##-## format, such as 0050.0500.5004.00-00.
is-name symbolic-name	Specifies the dynamic host name in is-name or is-name.##-## format. ##-## indicates the pseudonode ID-LSP fragment ID.	The value is a string of 1 to 70 characters.
