Hi there,
this is my lab setup:
<Cisco_2921> ----- CH-E1 (512k) ----- <Juniper_M320>
Cisco Interface Config:

I'm using a lsq-interfce because i need to apply a fragmentation-map to the lsq-interface for packet fragmentation to support quality of service for voice over the low speed link (512k).
Just for the background, this is the class of service config:
class-of-service {
schedulers {
replace: sch-EC-lsq-030049-lsq-0.1.0-20 {
transmit-rate percent 18;
buffer-size percent 18;
priority low;
}
replace: sch-ST-lsq-030049-lsq-0.1.0-20 {
transmit-rate percent 24;
buffer-size percent 24;
priority high;
}
replace: sch-BU-lsq-030049-lsq-0.1.0-20 {
transmit-rate percent 18;
buffer-size percent 18;
priority high;
}
replace: sch-VO-lsq-030049-lsq-0.1.0-20 {
transmit-rate percent 40;
buffer-size percent 40;
priority strict-high;
}
}
scheduler-maps {
scm-lsq-030049-lsq-0.1.0-20 {
forwarding-class Economy scheduler sch-EC-lsq-030049-lsq-0.1.0-20;
forwarding-class Business scheduler sch-BU-lsq-030049-lsq-0.1.0-20;
forwarding-class Stream scheduler sch-ST-lsq-030049-lsq-0.1.0-20;
forwarding-class Voice scheduler sch-VO-lsq-030049-lsq-0.1.0-20;
}
}
fragmentation-maps {
frm-lsq-030049-lsq-0.1.0-20 {
forwarding-class {
Economy {
fragment-threshold 320;
}
Stream {
fragment-threshold 320;
}
Business {
fragment-threshold 320;
}
Voice {
no-fragmentation;
}
}
}
}
interfaces {
replace: ds-1/2/2:1 {
scheduler-map scm-lsq-030049-lsq-0.1.0-20;
}
replace: lsq-0/1/0 {
unit 20 {
scheduler-map scm-lsq-030049-lsq-0.1.0-20;
fragmentation-map frm-lsq-030049-lsq-0.1.0-20;
}
}
}
}
OK, that being said - here is the problem:

I'm not able to bring any ip traffic over the link. Layer 2 is up.
Any Ideas?
