[SNMP4J] AgenPro MIB compiler problem

[Frank Fock]

Hi Ed,

There are many MIB compilers (including online
validation sites) that perform incomplete
syntax checks. This is something one should have
always in mind ;-)

The SEQUENCE definition is wrong, because in the
OBJECT-TYPE definition, you use
"RouterChassisAlarmBits" as syntax whereas in the
SEQUENCE you use "BITS". SMIv2 requires that the
syntax must be the exactly same (except that the
SEQUENCE syntax must not be extended by SIZE and
range restrictions, AKA subtyping) even if the base
types would match.

Best regards,
Frank
