Configuring PPP Users
If you configured the interface to authenticate peers using CHAP or PAP,
then you must add user account information for all peers that the interface
may authenticate.
When CHAP or PAP is enabled for server mode, the interface requests a
username and password from the remote peer. When the peer responds
with a username/password combination, the POS interface examines its PPP
LCP Server Users Table to verify the information is correct. If the account
information is verified correct, the connection is allowed; otherwise its
closed.
PAP Enables PAP on the current POS interface.
PAP-CHAP Enables both PAP and CHAP. Enabling both authentication
protocols allows for the interface to negotiate which one it
uses to identify a remote entity. The interface requests PAP
authentication first. If the remote entity is not configured or
refuses PAP authentication, the interface then requests CHAP
authentication. If CHAP authentication is rejected as well, the
interface cannot authenticate the host and therefore does
not allow the connection.
