Standard Cisco MIB/OID For Port Duplex Information?

    I'm trying to monitor a range of Cisco switches but have hit problems when
    attempting to get port duplex state and was wondering if there is a single MIB
    that I can use to get this information rather than looking at switch-specific

    I started off with a 2950, obtaining port information as available from
    RFC1213 but it didn't have duplex information. For duplex information it
    appeared that I head to go to the separate CISCO-C2900-MIB, but given it's name
    I am worried that it doesn't exist on the other switches. Is this MIB just
    badly named and is available everywhere else, or is there a specific MIB buried
    somewhere in the few hundred out there that are supported by all switches and
    have the information that I'm after?

    Probably not. Even Cisco's own CiscoWorks 2k LMS fails on correctly
    detecting (besides other things) duplex state of certain switches ports,
    releasing all sorts of false alarms. So that really looks like there is
    no *single* and *reliable* way to request it. Then again, maybe they just
    can't code (and exactly for that reason chose Java). The CW2k LMS sometimes
    leaves a strong taste of that, at last.
