Follow these steps to configure settings for DNS server address negotiation when the device is
functioning as the server in PPP negotiation:
To do… Use the command… Remarks
Enter system view system-view —
Create a VT interface and enter VT
interface view
Interface virtual-template number —
Enable the local end to assign a
DNS server address to the peer ppp ipcp dns primary-dns-address
[ secondary-dns-address ]
Required
By default, a device does not
assign a DNS server address to the
peer.
Enabling PPP traffic statistics collection
Introduction to PPP traffic statistics collection
PPP can generate traffic-based accounting statistics on each PPP link. The statistics include the amount of
the inbound and outbound information (in terms of bytes and the number of the packets) on a link. The
information can be used by AAA application modules for accounting and control purpose.

Enabling PPP user binding
Introduction to PPP user binding
Without knowing the domain of each use in advance, the PPP user binding function can bind users from
different domains to different virtual-template (VT) interfaces. The PPP user binding function works as
follows:
• Because the system does not know the domain of each user in advance, the system must
authenticate the users. After a user passes the authentication, the system obtains the user’s domain,
which is related to the user authentication result. For more information, see the related sections
above.
• After the user passes the authentication, if the interface is enabled with PPP user binding, the
function binds the user to the specified VT interface according to the configured PPP user binding
rule and the obtained domain name. Then, the function creates Virtual-Access (VA) interfaces based
on the VT interface, and performs network layer protocol negotiation and receives/sends packets
on the VA interfaces.
