Hi,
We have two separate sites running Juniper MX240 LNS with dynamic-profiles.
I am now testing site 2 with VoiP. Site 1 has been tested and works fine with no problem at all. I can fill the best effort queue so that ping packets are dropping and yet, VoiP is perfect still. Exactly what I wanted.
So, naturally, I copy the config from one system to the other system and the CoS does not work. Here is the route taken:
SIP Phone --> CPE --> LAC --> LNS --> Core -- Upstream ISP --> Other end of VoiP
The Core seems to be placing the traffic into the correct queue as when I look at the statistics on the interface, they are exactly as I would expect, and to confirm, I cleared them and re-tested.
However, on the LNS, NO packets are going into the SIP-VOICE queue..... However, on THW with the exact same configuration, using the same phone, the VoiP traffic goes into the SIP-VOICE queue ...... I have set queue 2 to be SIP-VOICE.
I have tried various troubleshooting techniques with no luck at all as to finding out why the traffic is not going into the correct queue.
Here is the dynamic-profile config and the relevant CoS:

Here is the firewall filter:
set firewall filter cos1 interface-specific
set firewall filter cos1 term 1 from dscp 46
set firewall filter cos1 term 1 from dscp 26
set firewall filter cos1 term 1 then count SIP-VOICE
set firewall filter cos1 term 1 then forwarding-class SIP-VOICE
set firewall filter cos1 term 1 then accept
set firewall filter cos1 term 4 from source-address 200.80.16.2/32
set firewall filter cos1 term 4 from source-address 200.80.16.3/32

set firewall filter cos1 term 4 then log
set firewall filter cos1 term 4 then forwarding-class SIP-VOICE

set firewall filter cos1 term 2 then forwarding-class best-effort

set firewall filter test-dscp term 1 from dscp ef
set firewall filter test-dscp term 1 then count dscp-ef
set firewall filter test-dscp term 1 then accept
set firewall filter test-dscp term 2 then accept
And the interface configuration:
set interfaces xe-1/1/1 unit 0 family inet filter input-list cos1
set interfaces xe-1/1/1 unit 0 family inet filter input-list filter-ssh
set interfaces xe-1/1/1 unit 0 family inet filter output filter-ssh-out
set interfaces xe-1/1/1 unit 0 family inet address 200.80.0.45/30
set interfaces xe-1/1/1 unit 0 family iso
set interfaces xe-1/1/1 unit 0 family inet6 address 3c61:e840:1143:ffff:ffff:ffff:0000:0001/126
Anyone know any more troubleshooting I can complete for this issue please?
