Thread: MIBs supported by a device

  1. MIBs supported by a device

    Hi.

    Is there any method to request the list of all supported MIBs from the SNMP node?

    Or the only way to learn about all supported MIBs is to check vendor's site?

  2. Re: MIBs supported by a device

    Just do 'snmpwalk' starting with .1

    do a walk on sysORTable which explains the mibs implemented in the
    device

    Well, this is an interesting subject. While some agents simply report
    the MIB modules they support in the sysORTable, this is actually not
    quite right if you take the description of the objects serious. The
    sysORTable was designed to report capability definitions. An attempt
    to liberalize the description of the sysORTable was shut down by the
    WG in the IETF. So as it stands, there is not standard way to learn
    about the MIB modules supported (as there is no standard way to
    configure an IP interface). Isn't this great?

    Pick some scalar in the MIB and try a get on it. If it times out, the
    MIB isn't supported. It's not the most elegant way to do things, but
    it works.

    You have to be careful with this because a) you might simply not get
    a value to access control rules or b) you might get response but the
    agent still does not implement the MIB if you are unlucky. So boxes
    do support some scalars just because you might plug in line cards
    that populate the MIB but if you do not have such cards installed,
    you surley will not get the MIB objects.
