Quick Start for Network AgentNetwork Interface Cards (NICs)NOTEThe NICs (network interface cards) on machines running NetworkAgent must be connected to your hub or switch, enabled in theoperating system, and activated.Each NIC used for monitoring must capture all packets on the network,not only the packets that are addressed directly to it (promiscuousmode).Complete the NIC hardware setup prior to software installation. Detailsin this section help you select the NICs you need to activate.After you set up the hardware and install Websense software, configure Network Agents in WebsenseManager. Specify the network segments where Network Agent should monitor or filter traffic, thenetwork interface card (NIC) to use, and the handling method for HTTP and other protocols.Use the planning worksheets to capture this information.NICs on the Network Agent machineYou can install Network Agent on 1 or more machines (but only once on each machine). EachNetwork Agent machine must use at least one designated network interface card (NIC). In theexample, Network Agent uses one NIC for monitoring traffic, and another to block.Each NIC that Network Agent uses for monitoring must be able to see all inbound and outboundtraffic assigned to it. Network Agent needs to see the user IP addresses. Do not place Network Agentin a location where the original user IP addresses have been translated by another network device(such as a router or other Network Address Translation device).SwitchesIf the device connected to the Network Agent machine is a switch, it must support port spanning (alsoknown as mirroring). Traffic on monitored ports is simultaneously sent to the monitoring port towhich Network Agent is connected.Quick Start 8 Network Agent
