IFNET_1.3.6.1.4.1.2011.5.25.41.3.42 hwIfControlFlapSuppressIPv6
Description
IFNET/4/IF_SUPPRESS_IP6:OID [OID] The IPv6 state of interface changed from unsuppress to suppress. (InterfaceIndex=[INTEGER], InterfaceExtIndex=[INTEGER], InterfaceName=[STRING], SuppressState=[INTEGER])
The IPv6 flap control function was configured on an interface. An alarm was generated when the interface changed from the suppression status to non-suppression status.

Parameters
| Name | Meaning |
|---|---|
OID |
Indicates the MIB object ID of the alarm. |
InterfaceIndex |
Indicates the interface index. |
InterfaceExtIndex |
Indicates the extended interface index. |
InterfaceName |
Indicates the interface name. |
SuppressState |
Indicates whether the interface is suppressed.
|
Impact on the System
After an interface enters the non-suppression status, the IFNET module will not report Up/Down events to the routing protocol module until the interface restores the suppression status.
Possible Causes
Cause 1:
The flap control function was configured on an interface. When alternating between Up and Down, the interface changed from the suppression status to the non-suppression status. This triggered the alarm. The threshold number of times that the interface alternates between Up and Down is configured using the control-flap command.
Procedure
- This alarm indicates that the interface was unstable. This
is because the physical link of the interface was faulty or the link
was unstable in a short period.
- If the alarm was generated on a physical interface, check whether the physical link of the interface works properly.
If the alarm was generated on a sub-interface, check whether the physical link of the main interface works properly.
- If the alarm was generated on a trunk interface, check whether the physical links of trunk member interface work properly.
- Collect alarm information and configuration information, and then contact technical support personnel.
