142 CHAPTER 7: PACKET OVER SONET ADMINISTRATION
To configure the interface to authenticate peers using PAP, then you must
add user account information for all peers that the interface may
authenticate.
When 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 it’s
closed.
