display isis statistics

Function

The display isis statistics 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 statistics [ [ ipv6 ] topology topology-name ] [ level-1 | level-2 | level-1-2 ] [ process-id ]

Parameters

Parameter	Description	Value
ipv6	Display statistics of IPv6 information.	-
topology topology-name	Specifies the name of a topology instance.	The value is a string of 1 to 31 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive) and can contain numbers, hyphens (-), or underlines (_). When double quotation marks are used around the string, spaces are allowed in the string.
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.	-
process-id	Specifies a process ID of IS-IS.	The value is an integer ranging from 1 to 4294967295.

Usage Guidelines

Usage Scenario

To monitor the status of a device or diagnose a fault, run the display isis statistics 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.
