Configuring Point-to-Point Protocol (PPP) 141
Configuring Server-Side Security Parameters
When a remote peer (client) calls into the POS interface and attempts to
establish a point-to-point connection, the interface functions as a PPP access
server. Enabling server-side authentication configures the POS interface to
authenticate all peers that call into it.
Configuring server-side authentication involves the following:
■ Specifying which protocol you want the interface to use to authenticate
clients. You can configure the interface to request CHAP authentication,
PAP authentication, or both in a specified order.
■ Specifying the hostname the POS interface sends to a client when
performing CHAP authentication.
■ Adding users to the PPP Server Users Table. User account information
includes a username and password. When a remote client responds to a
PAP challenge with a username and password, the system examines this
table to verify that the client has responded with the correct information.
If so, the connection is allowed; otherwise, the connection is closed.
Perform the following tasks within interface pos <c/s/i> mode to configure
PPP CHAP server-side security parameters:
