Configuring The Polling Feature - H3C SR8800-F Configuration Manual

Configuring MS-CHAP or MS-CHAP-V2 authentication (authenticator name is not configured)
Step
1. Enter system view.
2. Enter interface view.
3. Configure the
authenticator to
authenticate the
peer by using
MS-CHAP or
MS-CHAP-V2.
4. Configure local or
remote AAA
authentication.

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.
To configure the polling feature:
Step
1. Enter system view.
2. Enter interface view.
3. Set the keepalive interval.
4. Set the keepalive retry limit.

For local AAA authentication, the

For remote AAA authentication, the
username and password of the peer
must be configured on the remote AAA
server.
