How do I shut-off constant SNMP from MacBook ?

Well i going to blow you mind. Get to the nitty gritty of the BSD under the hood part of OS X. Get into the CUPS printing in OS X by going to: http://127.0.0.1:631/ .

Well. ... I eventually deleted the printer; re-added it; and had no SNMP /// then after re-start this morning, I am back to several hundred a minute as seen in a jpeg screen shot here:

this is extremely annoying. It's hard to believe this only affects my network.

Does this "chatty" behavior somehow affect your network in an adverse way (extremely long ping times, firewall warnings, unresponsive network devices, slow internet access, etc.), or is it a case of seeing something and thinking it's amiss?

Also, from doing some research online, it seems that having many routers (or perhaps more than one router between your Mac and the printer) can cause SNMP to exhibit weird behavior (even though it's not supposed to). Is your network setup simple (one router, many devices), or is it more complex with routers connected to routers, with devices interspersed?

Thanks for making me think ... and ... actually I first noticed a slowdown in DirecTV downloads via Ethernet and their "On Demand" setup.

Does the slowdown occur only with DirecTV downloads? If so, that may be a separate issue -- I would think that if the SNMP packets were causing a slowdown, it would affect the entire network, or at least the portion of the network (in the case of a multiple router setup) that the printer/Mac are connected to.

Nah ... I'd been mentally complaining that my entire DSL "experience" had been bragging ... which seemed to coincide with a printer upgrade ... and it's just a simple home network ..my Mac usually the only device aside from the printer and the DirecTV interface.

I've run the standard Broadbbandreports DSL test ... they seem at , or near, what they were a year ago.

But that aside, is it normal for a mac to continually hit a printer with SNMP requests? Anyone else able to run Wireshark and watch the en1 line (since I am Airport to the Airport-Extreme)


So, irrespective of IF the SNMP's cause a problem, is it normal?

Have you looked to see if the bonjour settings are going bad? To stop & Start bonjour you have to be comfortable with the Terminal (/Applications/Utilities/Terminal). This is not a tame thing to stop/start Bonjour. Here are the Terminal commands (here):

Stop Bonjour service:

sudo launchctl unload /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist

Start Bonjour service:

sudo launchctl load /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist

OK. First I verified thru Wireshark that the racket was still going on
Then I stopped mDNS and verified thru Activity-Mon that the entire process was stopped. Then I ran Wireshark capture and still see a continual flow of req-resp between the two.

I can't for the life of me recall how I stopped the junk two days ago .. I do remember how it started back up after starting the home network in the morning.

I tried deleting the printer from both CUPS interface and teh "Preferences" approach ... but the request-response stuff continues ... and I have tried rebooting the sys also .. tho I didn;t try it just now after stopping mDNS 'cuz it will most certainly be in the startup plist and get going before I can get into Terminal.

I have searched for viable .conf files for SNMP but anything I have modified dies not seem to be implemented/read by the system ... I was wondering if I could limit the amount if time it was on ... but like I said, I can't prove that mDNSresponder is reading anything that I have personally modified (and restarted system)
