[j-nsp] Per DS1 CoS on the M10i CHOC12

Has anyone gotten CoS working at a per DS1 level on the PE-1CHOC12SMIR-QPP
card in the M10i? Does anyone know if this is supported? Right now I'm not
sure it is. If so, what method did you use?
Here is what I am doing and it is causing a lot of tail drops in the BE
queue on ALL DS1s (not just the ones with the scheduler maps applied)
without the affected individual DS1 circuit being taxed that much
(~200kbps):
interfaces {
ge-0/0/1 {
traps;
mtu 1540;
link-mode full-duplex;
unit 0 {
family inet {
mtu 1500;
filter {
input INBOUND-PERIMETER_FILTER;
}
address x.x.x.x/31;
}
family iso {
mtu 1500;
}
family inet6 {
mtu 1500;
address xxxx:xxxx:x:x::xx/127;
}
family mpls;
}
}
}
firewall {
filter INBOUND-PERIMETER_FILTER {
term 1 {
from {
protocol [ udp tcp ];
port 5060;
}
then {
count sip;
forwarding-class assured-forwarding;
accept;
}
}
term 2 {
from {
protocol udp;
port 16384-32768;
}
then {
count rtp;
forwarding-class expedited-forwarding;
accept;
}
}
term 3 {
then {
count best-effort;
forwarding-class best-effort;
accept;
}
}
}
}
classifiers {
dscp VOIP_CLASS {
forwarding-class expedited-forwarding {
loss-priority high code-points ef;
}
forwarding-class assured-forwarding {
loss-priority high code-points af31;
loss-priority low code-points cs3;
}
forwarding-class best-effort {
loss-priority high code-points be;
}
}
}
forwarding-classes {
queue 0 expedited-forwarding;
queue 1 assured-forwarding;
queue 2 best-effort;
}
interfaces {
t1-0/2/0:1:1 {
scheduler-map VOIP_QOS_POLICY_OUTPUT;
}
}
scheduler-maps {
VOIP_QOS_POLICY_OUTPUT {
forwarding-class expedited-forwarding scheduler VOIP_EF;
forwarding-class assured-forwarding scheduler VOIP_AF;
forwarding-class best-effort scheduler VOIP_BE;
}
}
schedulers {
VOIP_EF {
transmit-rate percent 70;
priority high;
}
VOIP_AF {
transmit-rate percent 5;
priority medium-low;
}
VOIP_BE {
transmit-rate percent 25;
priority low;
}
}
Thanks,
Jason
