3.
Configure the
authenticator to
authenticate the
peer by using
MS-CHAP or
MS-CHAP-V2.
ppp authentication-mode
{
ms-chap
|
ms-chap-v2
} [
domain
{
isp-name
|
default enable isp-name
} ]
By default, PPP authentication is
disabled.
4.
Configure local or
remote AAA
authentication.
For local AAA authentication, the
username and password of the peer
must be configured on the authenticator.
For remote AAA authentication, the
username and password of the peer
must be configured on the remote AAA
server.
For more information about AAA
authentication, see "
The username and password of the
peer configured on the
authenticator or remote AAA server
must be the same as those
configured on the peer.
Configuring the polling feature
The polling feature checks PPP link state.
On an interface that uses PPP encapsulation, the link layer sends keepalives at keepalive intervals
to detect the availability of the peer. If the interface fails to receive keepalives when the keepalive
retry limit is reached, it tears down the link and reports a link layer down event.
To set the keepalive retry limit, use the
timer-hold retry
command.
On a slow link, increase the keepalive interval to prevent false shutdown of the interface. This
situation might occur when keepalives are delayed because a large packet is being transmitted on
the link.
The keepalive interval must be smaller than the negotiation timeout time.
To disable sending of keepalives, set the keepalive interval to 0.
