Description
Use
dialer-rule
to set the condition for a DCC call to be placed for a dialer access group either by
directly configuring a rule or by referencing an ACL.
Use
undo dialer-rule
to remove the setting.
You may configure a dial ACL to filter traffic that traverses a dialup interface. Packets fall into 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.
