Perhaps someone can help me find a device that would suite our needs? We currently have Cisco 3750 switches at each of our sites that are connected to an MPLS network. Some of the sites have very low speed links and are often saturated. We wanted to setup NETFLOW on the ports in question so we can easily see where the traffic is coming from but the Cisco 3750 switches do not support it. Instead of replacing all our switches, we'd like to see if there is some sort of IN-LINE appliance or solution so that we can keep everything as is and just add something within the path of our router and MPLS. Thanks.
