Lab 4.5.1 Identifying Traffic Flows

Step 1: Cable and configure the current network a. Referring to the topology diagram, connect the console (or rollover) cable to the console port on the router and the other cable end to the host computer with a DB-9 or DB-25 adapter to the COM 1 port. Ensure that power has been applied to both the host computer and router. b. Establish a HyperTerminal or other terminal emulation program to the router. c. From the command prompt on Host1, ping between Host1 and Discovery Server to confirm network connectivity. Troubleshoot and establish connectivity if the pings fail. Step 2: Configure NetFlow on the interfaces From the global configuration mode, issue the following commands to configure NetFlow: FC-CPE-1(config)# interface fastethernet 0/0 FC-CPE-1(config-if)# ip flow egress FC-CPE-1(config-if)# ip flow ingress FC-CPE-1(config-if)# interface fastethernet 0/1 FC-CPE-1(config-if)# ip flow ingress FC-CPE-1(config-if)# ip flow egress Step 3: Verify the NetFlow configuration a.
