Cisco 2600 router error: "unable to open socket on port 161"

By bgallaghe ·
I have done a bit of research regarding a strange message that is popping up on my Cisco 2612 router... It seems to be related to the configuration of the aux line but it does not seem to go away even when i unplug the modem completly. It is as follows:

*Mar 1 01:11:19.346: %IP_SNMP-3-SOCKET: can't open UDP socket
*Mar 1 01:11:19.346: Unable to open socket on port 161

It shows up every 20 or so seconds and it makes configuring the router impossible because it covers up the text you type. As follows is my running config (note that for some reason when I request the config, it goes ... well, CRAZY!) :

Cisco_2612#show running-configo ip route-cache protocol on I
