Parameters

Parameter Name	Parameter Meaning
Proc	Process ID
IfName	Interface name
SuppressPreviousStatus	Suppression previous status
SuppressCurrentStatus	Suppression current status
Reason	Suppression causes are as follows: 1: The suppression exits because the hold-max-cost timer expires. 2: The suppression exits because the hold-down timer expires. 3: A configuration change occurs. 4: A manual operation is performed to exit from flapping suppression. 5: The neighbor relationship frequently flaps. 6: Suppression is aborted forcibly using the reset isis process-id suppress-flapping peer[interface interface-type interface-number ] notify-peer command on the remote device.

Possible Causes

IS-IS neighbor relationship flapping suppression started, or the interface exited from the suppression.

Procedure

Run the display isis last-peer-change [ process-id | vpn-instance vpn-instance-name ] command to check whether frequent interface flapping occurs.
- If frequent interface flapping occurs, this trap message is informational only and no action is required.
- If no frequent interface flapping occurs, go to Step 2.
End.
