OSPF_1.3.6.1.2.1.14.16.2.6 ospfIfAuthFailure

OSPF_1.3.6.1.2.1.14.16.2.6 ospfIfAuthFailure

Description

OSPF/2/IFAUTFAIL:OID [oid]: A packet is received on a non-virtual interface from a router whose authentication key or authentication type conflicts with the local authentication key or authentication type. (IfIpAddress=[ip-address], AddressLessIf=[interface-index], ProcessId=[process-id], RouterId=[router-id], PacketSrc=[source-ip-address], ConfigErrorType=[error-type], PacketType=[packet-type], InstanceName=[instance-name])

The non-virtual-link interface authentication failed. The possible cause was that the configuration of the non-virtual-link interface authentication was incorrect.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.2.1.14.16.2.6 Major environmentalAlarm (6)

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

IfIpAddress

Indicates the IP address of the non-virtual-link interface.

AddressLessIf

Indicates the index of the interface.

ProcessId

Indicates the process ID.

RouterId

Indicates the ID of the local router.

PacketSrc

Indicates the source IP address of the packet.

ConfigErrorType

Indicates the error type.
  • 5: Auth type Mismatch
  • 6: Auth Failure

PacketType

Indicates the type of the packet.
  • 1: Hello packet
  • 2: DD packet
  • 3: Request packet
  • 4: Update packet
  • 5: Acknowledgement packet
  • 6: Update packet Retrans
  • 7: Update packet flood

InstanceName

Indicates the instance name.

Impact on the System

This trap message is generated after an interface receives a packet indicating authentication parameters are incorrectly configured.

Possible Causes

The configuration of interface authentication was incorrect.

Procedure

  1. Run the display current-configuration configuration ospf command to check whether area authentication configurations on the two router devices are consistent, and the display current- configuration interface interface-type interface-number command to check whether the interface authentication configurations on the two ends are consistent. The interface authentication takes precedence over the area authentication.

    • If so, go to Step 3.

    • If not, go to Step 2.

  2. Perform the following operations according to the networking:

    • If it is allowed to modify the configurations on the two ends to be consistent, go to Step 3.

    • If it is not allowed to modify the configurations on the two interfaces to be consistent, go to Step 4.

  3. If the authentication is in plain text, modify the authentication password. If the authentication is in cipher text, run the following commands to reconfigure the authentication on the two interfaces as required.

    Configure the interface authentication:
    • ospf authentication-mode { simple [ plain plain-text | [ cipher ] cipher-text ] | null }
    • ospf authentication-mode { md5 | hmac-md5 | hmac-sha256 } [ key-id { plain plain-text | [ cipher ] cipher-text } ]
    • ospf authentication-mode keychain keychain-name
    Configure the area authentication:
    • authentication-mode simple [ plain plain-text | [ cipher ] cipher-text ]
    • authentication-mode { md5 | hmac-md5 | hmac-sha256 } [ key-id { plain plain-text | [ cipher ] cipher-text } ]
    • authentication-mode keychain keychain-name
    Check whether the trap is cleared.
    • If so, go to Step 5.

    • If not, go to Step 4.

  4. Collect alarm information and configuration information, and then contact technical support personnel.
  5. End.
