Configure The Dialer Interface - Cisco 1812W - Integrated Services Router Wireless Configuration Manual

Chapter 4 Configuring PPP over ATM with NAT

Configure the Dialer Interface

The dialer interface indicates how to handle traffic from the clients, including, for example, default
routing information, the encapsulation protocol, and the dialer pool to use. It is also used for cloning
virtual access. Multiple PPPoA client sessions can be configured on an ATM interface, but each session
must use a separate dialer interface and a separate dialer pool.
Perform these steps to configure a dialer interface for the ATM interface on the router, starting in global
configuration mode.
Command
Step 1 interface dialer dialer-rotary-group-number
Example:
Router(config)# interface dialer 0

Step 2 ip address negotiated
Example:
Router(config-if)# ip address negotiated
Router(config-if)#
Step 3 ip mtu bytes
Example:
Router(config-if)# ip mtu 4470
Router(config-if)#
Step 4
encapsulation encapsulation-type
Example:
Router(config-if)# encapsulation ppp
Router(config-if)#
Step 5
ppp authentication {protocol1 [protocol2...]}
Example:

Configure the Dialer Interface
Purpose
Creates a dialer interface (numbered 0–255), and
enters into interface configuration mode.
Specifies that the IP address for the dialer
interface is obtained through PPP/IPCP (IP
Control Protocol) address negotiation.
Sets the size of the IP maximum transmission unit
(MTU). The default minimum is 128 bytes. The
maximum for ATM is 4470 bytes.
Sets the encapsulation type to PPP for the data
packets being transmitted and received.
Sets the PPP authentication method.
The example applies the Challenge Handshake
Authentication Protocol (CHAP).
For details about this command and additional
parameters that can be set, see the
Security Command Reference.
Specifies the dialer pool to use to connect to a
specific destination subnetwork.
