PPP configuration topology

When you configure the modem port on the switch to use PPP, you must also specify a PPP file. The PPP file is a text document which includes all additional PPP configuration parameters to include when the switch reboots. Enter one configuration parameter on each line with any required values.

You can configure the connection to use the Challenge-Handshake Authentication Protocol (CHAP) or the Password Authentication Protocol (PAP). Both protocols require a secrets file. The secrets file is a text document which includes the list of all users authorized to use the modem port. You must list one user on each line and include specific parameters. The format for each user is client server password IP address. The following list explains each option.

client: the name of the user. This value is the logon name of the authorized user. This value should be the name or ID of the user, similar to a Windows or UNIX logon.

server: the name of the remote device, which is often the dial-in server. Use an asterisk (*) to indicate any server name is acceptable.

password: the password for the user.

IP address: the IP address associated with the user.

The value for the IP address depends on the desired configuration of the modem. If all users must use the same IP address, you must specify the same IP address for all users in the file and it must be the same IP address that you configure as the peer-ip for the modem port. Configure the IP settings on the client to obtain an IP address automatically.
