H3C SecPath Series Security Products
Configure the data link protocol encapsulated on the interface to be PPP
Configure the polling interval
Configure PPP authentication mode, user name and user password
Advanced PPP configuration tasks include:
Configure PPP negotiation parameters
Configure PPP link quality control (LQC)
The fundamental configuration is the parameter setting that must be performed for
running PPP on the firewall, whereas the advanced configurations are the options that
can be configured as needed.

1.2.1 Configuring PPP Encapsulation on the Interface

Perform the following configuration in interface view.
Table 1-1 Configure PPP encapsulation on the interface
Configure PPP encapsulation on the interface.
The link layer protocol encapsulated on the dialer and virtual-template interfaces
defaults to PPP.

1.2.2 Configuring the Polling Interval

Data link protocols such as PPP, FR and HDLC use a timer to monitor the status of the
link periodically. The polling interval must be exactly equal at the two ends of the link for
properly working.
Perform the following configuration in interface view.
Table 1-2 Configure polling interval on the interface
Set the polling interval.
Reset polling interval
The polling interval defaults to 10 seconds. The cyclic polling operation will be closed if
the polling interval is set to 0.
Elongate this time to prevent net fluctuation for long-delay and high-congestion
network.
