Re: [OSL | CCIE_Voice] QOS WAN

Hi Justin,

Thanks for your reply.


After taking out and reapplying the config it appears that the HQ to SC issue 
for calls work.&nbsp; The calls between SB , HQ , SC also work.

However when inbound calls come from pstn to the H323 gateway leading to the 
PSTN&nbsp; I notice that it gives a fast busy. Upon removing QOS the calls work 
fine.

Questions:
================= 

1) Would&nbsp; you recommend applying wan qos manually? is it the same 
procedure ? Also how is it different from the auto qos option?

2) What would be a safe approach to take ?


3) My LAN QOS has not been setup on the switch ?&nbsp; Do you think that this 
could cause an issue on the WAN?


Regards,
Vir

For Site A - it looks like your serial sub interface 102 references DLCI 103, 
then suf-if 103 references DLCI 102...is that a typo or is that correct? 
&nbsp;Shut down one and verify that you can still get to the other (correct) 
site.

For Site B - I noticed an interesting line in your R2 output on physical s0/1/0 
it looks like it is set to 56K. &nbsp;I recently had this same issue but didn't 
have time to continue to troubleshoot. &nbsp;Whatever is causing that to show 
up may be part of your issue with your site B. &nbsp;


The way I got myself in that situation was by configuring under the wrong 
subinterface (and creating one) and then "no" sub-if without removing the 
map-class. &nbsp;When I get time to lab I plan to recreate this and then try 
putting the wrong sub-if back, remove the map class, then delete the sub-if.


I don't see anything that jumps out for your site C but will compare that to my 
results next time I lab (probably tomorrow)

Subject: Re: [OSL | CCIE_Voice] QOS WAN
At first glance those steps look ok. &nbsp;What do you see from "show traffic" 
and "show frame-r pvc #" on all three site routers?

For odd audio issues I would look at LAN QoS (make sure you're not policing too 
low) and ensure you don't have one-way LFI or cRTP (which looks like you moved 
crtp to policy-map already). &nbsp;For SC phones not registering double check 
to ensure your frts is keeping that PVC at 2M and its not at the default 56k 
once frts was enabled on physical interface.


Worst case you could back out the configuration, reload, and reapply the config 
either using auto qos or use your current config as a template and apply 
manually.
You could also post you full cli configs for review.

Hello All,

Any update? I am still waiting for a reply.

Subject: QOS WAN
hi All,

I am trying to connect HQ and SB with a 384 k frame relay
 PVC.Enable FRF.12 link fragmentation and interleave on the Frame Relay 
connections to
fragment large data packets and interleave voice packets to minimize delays. 
Max delay between fragments should be
set at 10 ms . Also provision RTP header compression.

Configure LLQ between HQ and SB to ensure voice bearer traffic gets priority 
queue treatment &amp; voice signalling


is guaranteed for 16kbps. Configure the priority queue accomodates
up to 4 G729 calls between HQ and SB.

Lastly, assume all bearer voice traffic has been marked with
traffic CS3.


Here are the steps I am following ...


-------------------------------------------------------------

1) Going to serial interface connecting from HQ to SB&nbsp; on the HQ router 
and changing the BW to 384

R1(conf)#int ser0/1/0.X
R1(config-subif)#bandwidth 384




2) Then apply "auto qos voip trust" under the interface

R1(conf)#int ser0/1/0.X point-to-point
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; #frame-relay interface-dlci 201
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; #auto qos voip trust


3) Then after the auto qos trust is applied . I remove


no match ip dscp af31


4) add ...priority 47
and bandwidth 16

5) Then remove "no frame-relay ip rtp header-compression"


6) Add the following...


map-class frame-relay AutoQoS-FR-Se0/1/0-201


frame-relay cir 364800
frame-relay bc 3648
frame-relay be 0
frame-relay mincir 364800
frame-relay fragment 480
service-policy output AutoQoS-Policy-Trust



7) add "compress ip header rtp"





8) I then move to SB router and do the same steps ( 1-7) on the interface 
connecting to HQ



9) After this I create a class map on HQ router with Site C


map-class frame-relay 2MBPS

frame-relay cir 2048000

frame-relay bc 20480
frame-relay be 0
frame-relay mincir 2048000


interface Serial0/1/0.2 point-to-point
description *** FR Connected to BR2 ***
frame-relay interface-dlci 202
class 2MBPS




Problem:
-------------------------

1)
 My phones in Site C unregister and don't register back after the above 
configuration.&nbsp; Looks like QOS breaks phone registration


2) The calls between sites appear to be slightly delayed.

3) Audio on the phones seems to be watery.



Questions :
------------------------ 



1) What is wrong with the above config?

2) Is there an easier and safer way for achieving the task?

3) How can the above task be achieved without causing problems?

Vir
