Configuring the Data Link Layer Protocol for E1, T1, and Serial Interfaces
Quick Start
Requiring the Peer to Authenticate Itself
1. Move to the PPP interface for the connection whose endpoint you want
to authenticate. From the global configuration mode context, enter:
Syntax: interface ppp <interface number>
2. Choose the authentication type:
Syntax: ppp authentication [chap | pap]
3. Enter the peer’s username and password. If you are using CHAP, the
username should be the peer’s hostname:
Syntax: username <username> password <password>
For example, if the peer’s hostname is Remote and the password is
procurve, enter:
ProCurve(config-ppp 1)# username Remote password procurve
Authenticating to a Peer
1. Move to the PPP interface for the connection whose endpoint requires the
router to authenticate itself. From the global configuration mode context,
enter:
Syntax: interface ppp <interface number>
2. Determine whether the peer uses PAP or CHAP authentication.
3. For PAP, enter the username and password you have agreed upon for the
local router:
Syntax: ppp pap sent-username <username> password <password>
For example, you might enter:
ProCurve(config-ppp 1)# ppp pap sent-username Local password procurve
4. For CHAP, enter the password you have agreed upon for the local router:
Syntax: ppp chap password <password>
Are you authenticating to the peer? Yes/No
local router’s username
local router’s password
