Cube QoS

Hi Everyone

I wanted to know can you someone point me in the right direction to  some documentation that will show me how to configure Qos for a Cube router. The reason I ask it becuase I have a location in NYC that everytime they try to transfer a call the call drops. The guy who's place I took opend up a case with TAC and the TAC engineer said " As previously stated on my previous email, the running-config suggests that there is no QoS service-policy applied to any interface; hence, the router is not applying any kind of priority queuing and will treat the packets on a FIFO (First In First Out) fashion. However, I would like to get a show tech-support output from the router in question for me to get a better look at the overall setup for this router as well as its interfaces". I just sent the TAC engineer the info that he requested. I don't know if TAC wil help with configuring QoS but if they don't what is the easiest way to configure QoS on the interfaces. Thanks in advance for the help and I look forward to your replies.

Re: Cube QoS

Hi Eric,

If you are looking for a sample QOS configuration on CUBE for voice traffic here is a general configuration:

!

class-map match-any rtp

match ip rtp 16384 16383

class-map match-any voice-control

match dscp cs3 af31

match protocol mgcp

match protocol h323

match protocol sip

match protocol skinny

 

policy-map voice-qos

class rtp

priority <bandwidth>

set dscp ef

class voice-control

bandwidth <bandwidth>

set dscp <whatever the provider wants to see for signaling, use 0 if unknown or if no queue is provisioned for signaling>

class class-default

fair-queue

random-detect dscp-based

set dscp 0

 

policy-map shaper

class class-default

shape average <upload speed of circuit>

service-policy voice-qos

 

interface <int>

service-policy output shaper

 

You can check the CUBE config guides for more details.
