Hi, we are an ISP and i have some issues with DSL connecections dropping off our LNS when the connection is maxed out or has high utilization, particularly on upload. I believe this is becuase it is dropping the LCP keepalive packets from the LNS (correct me if i am wrong) so the LNS connection thinks has dropped off. Is there a way i can setup a QoS policy on the router to prioritise these LCP packets? When creating a class-map, there is no option to match LCP packets. We are using a Cisco ASR-1001 for the LNS and a Cisco 867-VAEK9 as the DSL CPE. Below is the configuration of the virtual template on the LNS and the Dialer interface on the 867.
interface Virtual-Template1
ip unnumbered Loopback0
no ip proxy-arp
keepalive 2 3
ppp authentication chap
ppp ipcp dns 8.8.8.8 8.8.4.4
ppp multilink
end
interface Dialer1
ip address negotiated
ip virtual-reassembly in
encapsulation ppp
ip tcp adjust-mss 1452
dialer pool 1
keepalive 3
ppp reliable-link
ppp authentication chap callin
ppp chap hostname XXXX
ppp chap password XXXX
Any help would be much appreciated.
Thanks.
