Configuring a dialer interface
Before establishing a PPPoE session, you must first create a dialer interface and configure bundle
dial-on-demand routing (DDR) on the interface. Each PPPoE session uniquely corresponds to a dialer
bundle, and each dialer bundle uniquely corresponds to a dialer interface. Therefore, a PPPoE session
uniquely corresponds to a dialer interface.
Configuring a dialer interface for a PPPoE client
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a dialer access group
and configure a dial access
control rule.
dialer-group dialer-group rule
{ protocol-name { deny |
permit } | acl { acl-number |
name acl-number }
By default, no dialer group exists.
3. Create a dialer interface and
enter its view.
interface dialer number N/A
4. Assign an IP address to the
interface.
ip address { address mask |
ppp-negotiate }
By default, no IP address is configured.
5. Enable bundle DDR on the
interface.
dialer bundle enable By default, no DDR is enabled.
6. Associate the interface with
the dial access control rule by
associating the interface with
the corresponding dialer
access group.
dialer-group group-number
By default, a dialer interface is not
assigned to any dialer group.
7. Configure the link-idle
timeout timer. dialer timer idle idle [ in |
in-out ]
The default setting is 120 seconds.
When this timer is set to 0 seconds, the
PPPoE session operates in permanent
mode. Otherwise, the PPPoE session
operates in on-demand mode.
8. Configure the DDR
application to operate in
diagnostic mode.
dialer diagnose [ interval
interval ]
By default, the DDR application
operates in non-diagnostic mode.
When DDR operates in diagnostic
mode, the link-idle timeout timer is
ignored.
9. Set the auto-dial interval.
dialer timer autodial
autodial-interval
The default setting is 300 seconds.
In permanent or diagnostic mode, DDR
starts the auto-dial timer after the link is
disconnected and originates a new call
when the auto-dial timer expires.
H3C recommends that you set a shorter
auto-dial interval for DDR to soon
originate a new call.
