RE: [ECOS] snmpTrapOID

[Ali, Khurram]

SNMP defines many traps. 

The value of an SNMP object with sysUpTime as OID specifies the time
since the last reset for the SNMP node.

Likewise, the value of an SNMP object with snmpTrapOID as OID specifies
the trap that the SNMP message is referring to.

Hope this helps.

Dear Sir!

snmp v2 trap consists of:
     sysUpTime   // {1.3.6.1.2.1.1.3.0}
     snmpTrapOID // {1.3.6.1.6.3.1.1.4.1.0}
     varList     // optional, I can attach anyone variable or more

I can understand what is sysUpTime - it is a time, in timeticks, from
system power up till sending trap.

But what is snmpTrapOID? I know, it holds some OID, but what is sense
of the thing? What purpose it serves?

Sincerely yours
Yuriy Coureelo

From RFC 1448:
The second variable is snmpTrapOID.0, which contains
the administratively assigned name of the notification.

What does snmpTrapOID->OID should contain? I mean, snmpTrapOID
contains OID, which contains something else.
Should snmpTrapOID point to some variable OID, which is reason of
generating the trap?

This is not really an eCos issue. I suggest you read the RFCs and a
good book on SNMP.
