Test your routers access control lists with Agilents multi-port Packets and Protocols Application. Access control lists (ACLs) serve as filters for controlling the traffic that enters or leaves a routers interfaces. Primarily implemented for security reasons, ACLs instruct a router to block or forward traffic based on specific criteria, such as a packets source or destination address or an encapsulated upper-layer application, as indicated by the TCP port number.
ACLs are configured in firewall routers, border routers, or any intermediate router that needs to filter traffic. Separate lists are required for each network protocol the router supports, and each list contains multiple filter terms which must be tested to ensure that the routers interfaces drop or forward all matching packets accordingly.
With Agilents N2X, you can quickly generate the right traffic to verify your routers access control capabilities. This application note explains how to define streams that match specific ACL statements, then measure how well your device can apply these filter terms under realistic traffic loads.
Testing network devices has never been easier!
