    Any body known, if I cant make any query snmp for see the error CRC in
    specific interface to the router Cisco.

    Which is the OID ?

    Thank you

    I am pretty sure that you can use the standard rfc1513,
    sorry I forget the exact number, "interface" mib for that.


    then append ".interfaceindex" for the interface you want.
    this counter includes all error types.
    There is also a standard dot3 transmission mib
    that has more detail, IIRC.

    Thank you

    I want, for example, when you do show interface Serial 0/0, you see de
    CRC error or Drops paquet, I want to Known, the mib that I consult and
    obtend the same result.

    I try with the, bat the result is no the same

    Last clearing of "show interface" counters 17:09:17

    The "sh int" counters have been cleared.
    The snmp counters cannot be cleared.

    How can I clear the the snmp counter by have the same information ?

    Thank you

    "The snmp counters cannot be cleared.".
    I cannot think how else to say it.
    I will try. There is no way to clear the snmp counters.
    The snmp counters are initialised on system reset and
    cannot be cleared otherwise.
    : -))

    After startup if you do not clear the interface counters then
    they will remain in step with the snmp counters however:-

    The snmp counters often have different definitions
    from the sh int counters and so will differ.
    The snmp counters (well the ones I mentiond anyway)
    are 32 bit counters. 0 to about 4,000,000,000. These
    counters may well overflow and wrap to zero before
    the sh int counters many of which are now 64 bit counters.
    I think that I will be long dead before the 64 bit counters wrap.
