Trap Buffer Description

The status of peer flapping suppress is changed.(ProcessId=[ProcessId], AreaId=[AreaId], ifAreaId=[ifAreaId], ifIndex=[ifIndex], ifName=[ifName], SuppressStatus=[SuppressStatus], SuppressReason=[SuppressReason])

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

Trap Buffer Parameters

Parameter	Description
ProcessId	Process ID.
AreaId	Area ID.
ifAreaId	ID of the area to which the interface belongs.
ifIndex	Interface index.
ifName	Interface name.
SuppressStatus	Mode in which neighbor relationship flapping is suppressed: 1: OSPF neighbor relationship flapping suppression is not started yet. 2: OSPF neighbor relationship flapping suppression works in Hold-down mode. 3: OSPF neighbor relationship flapping suppression works in Hold-max-cost mode.
SuppressReason	Cause for the change in the status of neighbor relationship flapping suppression: 1: The interval between two successive neighbor status changes from Full to a non-Full state was longer than the resume interval. 2: A configuration was changed. For example, the OSPF process was reset. 3: An interface was forced to exit from OSPF neighbor relationship flapping suppression using the reset ospf suppress-flapping peer command. 4: The OSPF neighbor relationship flapped frequently. 5: OSPF neighbor relationship flapping suppression exited from Hold-down mode and began to work in Hold-max-cost mode.

Impact on the System

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

Possible Causes

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

Procedure

1. Check whether frequent neighbor relationship flapping occurs on the interface:

If yes, no further action is required.
If no, go to Step 2.

2. Run the reset ospf suppress-flapping process-id peer [ interface-type interface-number ] [ notify-peer ] command to forcibly exit the neighbor relationship flapping suppression phase.

3. End.
