Usage guidelines
You can configure a dial ACL to filter traffic that traverses a dialup interface. Packets include two
categories, depending on whether they are in compliance with the permit or deny statements in the dial
ACL.
• Packets that match a permit statement or that do not match any deny statements. When receiving
such a packet, DCC either sends it out if a link is present and resets the idle-timeout timer or
originates a new call to set up a link if no link is present.
• Packets that do not match any permit statements or that match a deny statement. When receiving
such a packet, DCC either sends it out without resetting the idle-timeout timer if a link is present, or
drops it without originating calls for link setup if no link is present.
