display isis statistics

Function

The display isis statistics command displays IS-IS process statistics.

Format

display isis statistics packet [ interface [ interface-type interface-number ] ]

display isis statistics [ updated-lsp [ history ] ] [ level-1 | level-2 | level-1-2 ] [ process-id | vpn-instance vpn-instance-name ]

display isis process-id statistics [ [ [ updated-lsp [ history ] ] [ level-1 | level-2 | level-1-2 ] ] | packet ]

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731S-H, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730S-H, and S6730-H support updated-lsp and history parameters.

Parameters

Parameter	Description	Value
packet	Displays IS-IS packet statistics.	-
interface interface-type interface-number	Displays IS-IS packet statistics on a specified interface.	-
updated-lsp	Displays real-time data of received LSPs. By default, statistics about the LSPs received within the last 1 hour are displayed.	-
history	Displays historical data of received LSPs. By default, statistics about the LSPs received within the last 24 hours are displayed.	-
level-1	Displays IS-IS Level-1 statistics.	-
level-2	Displays IS-IS Level-2 statistics.	-
level-1-2	Displays IS-IS Level-1-2 statistics.	-
process-id	Displays statistics in a specified IS-IS process.	The value is an integer that ranges from 1 to 65535.
vpn-instance vpn-instance-name	Displays statistics about the IS-IS multi-instance process in a specified VPN instance.	The value must be an existing VPN instance name.

Usage Guidelines

You can use the display isis statistics command to view IS-IS process statistics, including the number of routes learned from other IS-IS devices, number of routes imported from other routing protocols, number of locally generated LSPs, and convergence priorities of IS-IS routes.
