Re: SNMP Traps

Traps are one of the ways that SNMP (Simple Network Management Protocol). What you are seeing is that when that line is varied on the 'Trap' is triggered. Any server that has registered with your System i to recieve traps would have gotten this message. Normally this is none in the System i world. The other thing SNMP can do is reply to requests for various information. There are thousands of MIBs (Management Information Bases) available and each defines some bits of data such as number of bytes transferred over a particular line, number of bytes recieved on a particular line etc.
The net of it is that you needn't worry about this message. To make them stop (and you're sure you don't use SNMP for anything) you can stop the SNMP service.

Every morning I see a series of messages in the QSYSOPR message queue about:

    Line QLCLDIAL01 varied on successfully
    Controller QLCLDNET contacted on line QLCLDIAL01
    SNMP linkUp trap generated
    SNMP linkDown trap generated
This series actually appears twice on our production box and once on our backup box. 


I checked iNav and the SNMP server is running on both boxes.
I pulled up the Simple Network Management Protocol (SNMP) Support manual (SC41-5412), but I couldn't find anything about traps, except how to start and end them. Nothing about what they are.
I'm not much of a hardware person, but I know that we don;t use the i5 for email. Isn't that what the SMTP server is for? Do I really need it started for anything else? 

In brief, what's going on here?
