When modifying the "unix.asn1" MIB to include an enterpriseSpecific variable, we found that we could generate an enterpriseSpecific event which could be trapped by DECmcc T1.2.4. When doing a "SHOW CHARACTERISTICS" on "trapper" we got the infamous "--Attribute Not Gettable" error message for "dataTrap" indicating that the agent was not cooperating. Here is what was added to the bottom of "unix.asn1" (ISODE agent): ---------------------------------------------------------------------- trapper OBJECT IDENTIFIER ::= { unix 8} dataTrap OBJECT-TYPE SYNTAX DisplayString (SIZE (0..79)) ACCESS read-write STATUS mandatory DESCRIPTION "The trap used for all groups wanting to send a critical message to me." ::= { trapper 1 } END ----------------------------------------------------------------------- Can anyone see what is wrong with this?? If we change the "SYNTAX" line above to read SYNTAX INTEGER we can get a value returned by the agent. If you need more of the MIB, I'll get it for you, but I have to type it all in by hand. Thanks, Dan

2222.1 | enterpriseSpecific traps are returned even if trap is not defined in vendor mib | DANZO::CARR | Thu Jan 30 1992 09:06 | 4 | |
It's not clear to me what you're trying to accomplish. What does this new object have to do with enterpriseSpecific traps? | |||||
2222.2 | More on SNMP traps | CUJO::HILL | Dan Hill-Net.Mgt.-Customer Resident | Thu Jan 30 1992 11:50 | 30 |
Dan, Basically, my customer has taken the ISODE MIB (unix.asn1) and added the object definitions mentioned in .0 . He then modified the ISODE daemon code to include variable list definitions of the objects mentioned (trapper & dataTrap). The ISODE daemon uses an smux_trap procedure call to generate the enterpriseSpecific event trap, with data then being passed to the SNMP daemon via smux_trap. PROBLEM: We have seen the "string" and "integer" data come across on a SUN running SUNnet Manager, but SnM can display only INTEGER data. (By the way, SnM is being tested against DECmcc to see which works better for this task.) DECmcc SNMP AM works well to sink the event and alarm the icon, but we can't do a "SHOW CHARACTERISTICS" on the ISODE (unix) private MIB object (trapper) to see anything but "--Attribute Not Gettable" for the "dataTrap" object. QUESTIONS: Is there something missing (like SEQUENCE OF) in the MIB definition as described in .0 ? Before I got the SINK process to work, I was getting SNMP event messages logged via OPCOM on my VAXstation. Is there a command or logical that can be used to force this to happen again? Thanks, -Dan |
