Configuring CHAP on the Dialer Interface

With GSM HSDPA 3G wireless modem cards, you may need to configure either Challenge Handshake Authentication Protocol (CHAP) or Password Authentication Protocol (PAP) for authentication with the service provider network. The service provider must supply the username and password, which you configure in an access profile. You then specify this access profile in a dialer interface.

Before You Begin

Configure a dialer interface. See Configuring the Dialer Interface.

In this example, you configure the username and password in the CHAP access profile chap-1, then associate the chap-1 profile with the dialer interface dl0.

To configure a CHAP access profile:

user@host# set access profile chap-1 client clientX chap-secret &7a^6b%5c

To associate the CHAP access profile with a dialer interface:

user@host# set interfaces dl0 unit 0 ppp-options chap access-profile chap-1
