display isis statistics updated-lsp

Function

The display isis statistics updated-lsp command displays the statistics of an IS-IS process, including the routes that are learned from other IS-IS routers, routes that are imported from other protocols, the convergence priority of IS-IS routes, and LSPs that are generated locally.

Format

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

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

Parameters

Parameter	Description	Value
process-id	Specifies a process ID of IS-IS.	The value is an integer ranging from 1 to 4294967295.
updated-lsp	Displays statistics of updated LSPs.	-
history	Displays statistics of recorded updated LSPs.	-
level-1	Displays statistics of IS-IS Level-1.	-
level-2	Displays statistics of IS-IS Level-2.	-
level-1-2	Displays statistics of IS-IS Level-1-2.	-
vpn-instance vpn-instance-name	Displays statistics of the instance to which an IS-IS process belongs.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.

Usage Guidelines

Usage Scenario

To monitor the status of a device or diagnose a fault, run the display isis statistics updated-lsp command to view the status of the device and statistics that it collects. The command output helps you collect traffic statistics and troubleshoot the device.

If the statistics are all 0, check whether an IS-IS neighbor relationship is established, the LSDB information is complete, or the SPT calculation is correct.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display the statistics of IS-IS.
