protocol ppp

Use this command to configure PPP control traffic to be protected by QoS.

Protecting PPP control protocol ensures the PPPoE interface goes up and is

maintained up over time. Not protecting PPP control protocol can lead to the

PPPoE interface going down in case of congestion.

When GoS is configured for a PPPoE interface, always protect PPP control

protocol. PPP control protocol concerns the LCP phase, NCP phase and PPP

keep-alive. LCP and NCP (see RFC 1661) are to negotiate and bring up a

PPP link. PPP keep-alive are PPP control packets periodically exchanged to

control if the link is still UP.

Syntax config protocol ppp gq <class>

Parameters qg class Enter the quality group class.

Example The following command creates the quality group ppp_protect then assigns

it.

> config qos group ppp_protect qg A3 type policed committed

100000

> config protocol ppp qg ppp_protect

commands

display protocol ppp

show protocol ppp

show interface ppp
