The display isis avoid-microloop information command displays anti-micro-loop information.

Format

display isis [ process-id ] avoid-microloop information [ ipv6 ] [ level-1 | level-2 ] [ systemid systemid ]

display isis [ process-id ] avoid-microloop information [ ipv6 ] [ level-1 | level-2 ] [ systemid systemid ] flex-algo flex-algo-id

Parameters

Parameter	Description	Value
process-id	Specifies the ID of a process whose anti-micro-loop information is to be displayed. If this parameter is not configured, anti-micro-loop information of all processes is displayed.	The value is an integer ranging from 1 to 4294967295.
ipv6	Displays anti-micro-loop information in IPv6 topology.	-
level-1	Displays anti-micro-loop information on nodes in Level-1 areas.	-
level-2	Displays anti-micro-loop information on nodes in Level-2 areas. If no level is specified, anti-micro-loop information of nodes in all areas is displayed.	-
systemid systemid	Specifies the system ID or pseudo node ID.	The value is a hexadecimal integer in the format of XXXX.XXXX.XXXX.

Usage Guidelines

Usage Scenario

After the SR anti-micro-loop function is enabled, run the display isis avoid-microloop information command to view anti-micro-loop information on nodes. The command output contains the anti-micro-loop type, cause for failures, and date and time when the device entered and exited the anti-microloop state.

Example

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

# After the SR anti-micro-loop function is enabled, view anti-micro-loop information on nodes. The command output contains the anti-micro-loop type, cause for failures, and date and time when the device entered and exited the anti-microloop state.
