Our network is built on a Cisco 1811 router and two Catalyst 2960 switches. We have a need to monitor all web traffic that hits the WAN based on IP or Mac address of our users. I'm familiar with Cisco's IP accounting and have been reading up on various solutions: SNMP Traffic Grapher, Netflow reporters, using a mirrored port on one of the switches( tough because we use 2 48 hole switches) and using something like Network Probe or Colasoft Capsa to sift through the traffic. We're a small company of about 60 users. I need this to be a low cost solution, easily implemented and easily interpreted. Basically, they want to be able to see who's spending how much time on what websites. Suggestions, please.
