    hi ,all
    i have a problem about ethernet type,
    LNS often ejects alert message like this:
    https://www.wilderssecurity.com/attachment.php?attachmentid=183304&stc=1&d=1158553216
    what does this type of the ethernet means?

    I went to http://www.iana.org/assignments/ethernet-numbers to find information about ethernet type.
    but the result is like these :

    Ethernet Exp. Ethernet Description
    ------------- ------------- -----------
    decimal Hex decimal octal
    0000 0000-05DC - - IEEE802.3 Length Field

    from 0x0000 to 0x05DC ,the description is IEEE802.3 Length Field.
    so who can tell me about type 0x002C ,0x00e2 , 0x0063, 0x0054 ,and so on...


    thank to all.
    thanks

    Hi cluefly :)

    You say you have a problem but not what is the problem... ;-)

    The Ethernet type for IPV4 is 0x0800 or 800 in the raw log of LNS.

    Ref.: http://en.wikipedia.org/wiki/Ethernet

    May be the problem is with the choice of Network Adapter in LNS?

    Be more specific please.

    :)

    When the number is below 1500 (5DC in hexa), it is not a type but a length.
    0026 is common but I don't know what it is exactly. I thought it could be used by some netbeui ethernet frames, but this protocol is supposed to have a type normally.

    hi,, Frederic
    thank you for your reply !

    yes,the number is below 1500 (5DC in hex), it is a length.
    so when the number is below 1500 ,i will get no information besides length?
