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.

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.

You can use either J-Web or the CLI configuration editor to configure the CHAP access profile.
