• In the RS-DCC approach, make the configuration on dialer interfaces and preferably the same
configuration on physical dialup interfaces on the calling side to guarantee the reliability of PPP
link parameters negotiation; on the called side, make the configuration on physical dialup
interfaces.

Associating a DCC dial ACL with the dialup interface
You can configure a dial ACL to filter traffic traversing a dialup interface. Packets include the
following categories, depending on whether they comply with the permit or deny statements in the
dial ACL:
• Packets matching 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 not matching 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.
For DCC to send packets correctly, configure a dial ACL and associate it with the concerned dialup
interface (physical or dialer interface) by using the dialer-group command. You can either configure
a dial ACL directly using the dialer-rule command or reference an existing ACL.
To associate a dial ACL with the dialup interface:
Step Command
1. Enter system view.
system-view
2. Configure a dial ACL for a dialer access group,
specifying the conditions triggering DCC calls.
dialer-rule
group-number { protocol-name {
deny
|
permit
} |
acl
{ acl-number |
name
acl-name } }
3. Enter dialup interface (physical or dialer
interface) view.
interface
interface-type interface-number
4. Associate the dialup interface with the dial ACL
by associating the interface with the
corresponding dialer access group.
dialer-group
group-number
Make sure that the group-number arguments in the dialer-rule and dialer-group commands take
the same value.
Configuring C-DCC
In the C-DCC approach, you can configure DCC parameters for a physical interface using one of the
following methods:
• Directly configure DCC parameters on the physical interface. This is applicable only to
one-to-one calls or one-to-many calls.
• Bind the interface to a dialer interface by assigning it to the dialer circular group associated with
the dialer interface. The interface can inherit the DCC parameters configured on the dialer
interface. This is applicable to many-to-one and many-to-many calls, in addition to one-to-many
and one-to-one calls.
A dialer circular group associates a dialer interface with a group of physical interfaces. All physical
interfaces in the group inherit the DCC configurations on the dialer interface. If the dialer interface is
