Network Advisor / Webtools -> SNMP Enable/Disable Authentication Trap

  • 1.  Network Advisor / Webtools -> SNMP Enable/Disable Authentication Trap

    Posted 12-01-2014 01:06 AM

    Since the Network Advisor is upgraded from 12.0.1 to 12.1.6, we received a lot of messages about Authenticaton failure.

     

    Severity

    - INFO

    Source name

    - Aapje

    Origin

    - SNMP Trap

    Category

    - Product Event

    Description

    - Authentication failure

    Module Name

    - Prodcut Event

     

    When I disabled the option, Enable/Disable Authentication Trap, in the Switch Management (tab: SNMP) (webtools).

    It solved the " problem " .

     

    But, what is the issue with the option? And what doest it?

    Hi,

     

    According to the manuals:

     

    authTraps, When enabled, the authentication trap (authenticationFailure) is transmitted to a configured trap recipient in the event that the agent receives a protocol message that is not properly authenticated. In the context of SNMPv1 and SNMPv2c, this means that a request contains a community string that is not known to the agent. The default value for this parameter is 0 (disabled).

     

    An authenticationFailure trap signifies that the sending protocol entity is the addressee of a protocol message that is not properly authenticated. While implementations of the SNMP must be capable of generating this trap, they must also be capable of suppressing the emission of such traps through an implementation-specific mechanism.


    This trap is generated when you perform GET or SET with invalid community strings (snmpv1).

     

     

    So there must be some host accessing the switch via SNMP with the wrong credentials.

     

     

    Rgds,

    Felipon
