CSX200 Configuration with QuickSET
66 CSX200 Family User’s Guide
When an IP Access Control List (ACL) is enabled on a router port, each packet forwarded out this
port is first checked against the ACL. If the address(es) of a packet match the address(es) in the
first filter in the list, the packet is permitted or denied as specified by that filter. If there is no match,
the packet is checked against the second filter, and so on, until a match is found, or until the packet
has been checked against all of the filters in the list. If the packet does not match any of the filters,
then the packet is permitted to pass through the port.
