I think I will take my chances! I'm already dealing with the request to get
the information I want from the devices managed, so i'll put some extra code
to recognize when a request is not part of my MIB.

The MIB is all consisted of Integers and Strings and enums. Like This:
k3lDeviceCount OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-only
STATUS current
DESCRIPTION "Numero de placas ativas no sistema."
::= { KhompDataDeviceCount}
k3lDeviceType OBJECT-TYPE
SYNTAX INTEGER
{
kdtE1(0),
kdtFXO(1),
kdtConf(2),
kdtPR(3),
kdtE1GW(4),
kdtFXOVoIP(5),
kdtE1IP(6),
kdtE1Spx(7),
kdtGWIP(8),
kdtFXS(9),
kdtFXSSpx(10),
kdtGSM(11),
kdtGSMSpx(12)
}
MAX-ACCESS read-only
STATUS current
DESCRIPTION " Tipo de uma placa."
::= { KhompDataDeviceType }
linkCount OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-only
STATUS current
DESCRIPTION "Numero de links."
::= { KhompDataDeviceConfig 1 }
channelCount OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-only
STATUS current
DESCRIPTION "Numero de canais."
::= { KhompDataDeviceConfig 2 }
Sorry if i'm not responding your question right. I'm new to SNMP and
Net-SNMP and there's also the language problem(i'm brazilian). By the way,
this table helpers you mentioned, are the conf files for mib2c?? :P
