[j-nsp] Move traffic to strict-priority-queue on MX

[Robert Hass]

Hi
I have deployment based on MX routers where I have to put traffic coming
from one interface (it's video traffic - multicast) to
strict-priority-queue on egress interface - core facing interface.

Topology is simple:

Ingress interfaces:
- ge-1/0/1.0 - interface with video #1
- irb.100 - interface with video #2 (there is IRB mapped for ge-1/0/2)
- ge-1/0/3.0 - interface where IP customers are connected (best-effor
traffic)

Egress interfaces:
- ge-1/0/5 - core-facing interface #1
- ge-1/0/6 - core-facing interface #2

My goal are:
- clear DSCP bits for traffic coming from ge-1/0/3.0, put this traffic on
best-effort queue
- set EF DSCP bit for traffic coming from video interfaces (ge-1/0/1.0 and
irb.100)

Finally what I configured:
# Clear DSCP + BestEffort queue
set firewall filter BestEff term 1 then forwarding-class best-effort
set firewall filter BestEff term 1 then dscp cs0
set interfaces ge-1/0/3 unit 0 family inet filter input BestEff

# Set EF DSCP + ExpeditiedForwarding queue
set firewall filter Set_EF term 1 then forwarding-class expedited-forwarding
set firewall filter Set_EF term 1 then dscp ef
set interfaces ge-1/0/1 unit 0 family inet filter input Set_EF
set interfaces irb unit 100 family inet filter input Set_EF

But It looks that it's not working. What I missing ?
