Testing Access Control Lists
Test your router’s access control lists with
Agilent’s multi-port Packets and Protocols Application.
Access control lists (ACLs) serve as filters for controlling
the traffic that enters or leaves a router’s interfaces.
Primarily implemented for security reasons, ACLs instruct
a router to block or forward traffic based on specific
criteria, such as a packet’s 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
router’s interfaces drop or forward all matching
packets accordingly.
With Agilent’s N2X, you can quickly generate
the right traffic to verify your router’s 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.
