Great! I've gotten great feedback on this. Will this continue to alert me on this rule excluding that IP?
I am using the -o option on the snort root command now.

I have a sig (below) that grabs SNMP traffic. How can I exclude 1 internal IP from the rule?
alert udp $EXTERNAL_NET any -> $HOME_NET 161 (msg:"SNMP request udp"; reference:cve,CAN-2002-0012; reference:cve,CAN-2002-0013; sid:1417; rev:2; classtype:attempted-recon;)

thanks in advanced
