MibLoaderException when mibble load mib file

wsliou commented 10 years ago

Hello I got a issue while loading mib files. MibLoaderException getLog show error: undefined symbol 'none'

The mib file can download from here http://nickos.free.fr/MIB/Switch/ECS4610-24F/ECS4610-24F_V1.2.2.1.mib

Below is detail console error message

MibLoaderException occurred!! Warning: in /home/ubuntu/mibs/ECS4610-24F_V1.2.2.1.mib: line 1267: missing import for 'Counter64', using definition from SNMPv2-SMI

Is this mib file invalid or this is a loader bug?

There are two errors in the MIB file (as reported above) + a number of warnings. The problematic definitions are the following:

ospfMultiProcessIfAuthKey OBJECT-TYPE
    SYNTAX       OCTET STRING (SIZE (0..8))
    MAX-ACCESS   read-write
    STATUS       current
    DESCRIPTION
        "The cleartext password used as an OSPF authentication key when
         simplePassword security is enabled.  This object does not access any
         OSPF cryptogaphic (e.g., MD5) authentication key under any
         circumstance.

         If the key length is shorter than 8 octets, th agent will left adjust
         and zero fill to 8 octets.

         Unauthenticated interfaces need no authentication key, and simple
         password authentication cannot us a key of more than 8 octets.

         Note that the use of simplePassword authentication is NOT recommended
         when there is concern regarding attack upon the OSPF system.
         SimplePassword authentication is only sufficient to protect against
         accidental misconfigurations because it re-uses cleartext passwords
         [RFC1704].

         When read, ospfIfAuthKey always returns an octet string of length zero.
         This is a private substitution for ospfIfAuthKey of RFC1253."
    DEFVAL { none }
    ::= { ospfMultiProcessIfEntry 16 }

and

ospfMultiProcessVirtIfAuthKey OBJECT-TYPE
    SYNTAX       OCTET STRING (SIZE(0..8))
    MAX-ACCESS   read-write
    STATUS       current
    DESCRIPTION
        "The cleartext password used as an OSPF authentication key when
         simplePassword security is enabled.  This object does not access any
         OSPF cryptogaphic (e.g., MD5) authentication key under any

    DEFVAL { none }
    ::= { ospfMultiProcessVirtIfEntry 9 }

The problem here is the DEFVAL part that refers to a value none that hasn't been defined either in the MIB itself or in one of the imports. I guess the proper value should be "" for an empty string here, but it is hard to guess.

Best solution is probably to comment out the DEFVAL part for now and request a corrected MIB file from the equipment vendor.
