Trap Buffer Description

The status of peer flapping suppress is changed.(isisSysInstance=[isisSysInstance], isisCircIndex=[isisCircIndex], isisCircIfIndex=[isisCircIfIndex], ifIndex=[ifIndex], ifName=[ifName], SuppressStatus=[hwIsisPeerFlappingSuppressStatus], Reason=[Reason])

The status of IS-IS neighbor relationship flapping suppression changed on the local interface.

Trap Buffer Parameters

Parameter	Description
isisSysInstance	IS-IS instance ID.
isisCircIndex	IS-IS interface index.
isisCircIfIndex	IS-IS interface IF index.
ifIndex	Interface index.
ifName	Interface name.
hwIsisPeerFlappingSuppressStatus	Suppression status are as follows: None: IS-IS neighbor relationship flapping suppression is not started yet. Hold-down: IS-IS neighbor relationship flapping suppression works in Hold-down mode. Hold-max-cost: IS-IS neighbor relationship flapping suppression works in Hold-max-cost mode.
Reason	Suppression causes are as follows: The suppression exits because the hold-max-cost timer expires. The suppression exits because the hold-down timer expires. A configuration change occurs. A manual operation is performed to exit from flapping suppression. The neighbor relationship frequently flaps. The Hold-down mode exits, and then the Hold-max-cost mode takes effect.

Impact on the System

Services may be interrupted if IS-IS neighbor relationship flapping suppression persists on the interface.

Possible Causes

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

Procedure

1. Run the display isis last-peer-change [process-id | vpn-instance vpn-instance-name] command to check whether the interface frequently alternates between Up and Down states and whether the cause matches the change reason.

If yes, this log message is informational only, and no action is required.
If no, go to Step 2.

2. Run the reset isis suppress-flapping process-id peer [interface interface-type interface-number] [notify-peer] command to forcibly exit from peer flapping suppression.

3. End.
