WS-C4506E Sup 6E - Avaya VoIP Configuration Settings

NC16390371 · ‎02-21-2011

I am trying to get a second set of eyes with folks that have experience configuring WS-C4506E's to support Avaya VoIP PoE phones. The following is the configuration that has been applied. I would like to see if their are any improvements that I can make to provide the best configuration. Please note I have limited exposure and experience with applying QoS settings to LAN Switches. If there other questions or it makes sense to post a particular output please do not hesitate to let me know. Thanks

This is pretty much a stock standard AutoQos configuration

.

ONe thing you have to make sure is the values in the following groups:

class AutoQos-VoIP-Control-QosGroup26
   set dscp af31
   set cos 3
    bandwidth remaining percent 5
class AutoQos-VoIP-Control-QosGroup24
   set dscp cs3
   set cos 3
    bandwidth remaining percent 5

because you have your access port set to trust any incoming dscp value, you must make sure that your phones are set to send the right DSCP value.

I am not sure where you set that in Avaya, but make sure you double check.

I too am deploying a 4510E with a sup7E in our environment. This is a new sup module that we don't have as part of our WAN enterprise till now.

I was looking for the same answers regarding AVAYA 4620 model phones.

If possible can we have a bullet proof configuration for QoS for these switches? The phones use DSCP. I'm not sure that auto qos voip trust would be the right parameter to put in under the interface configuraitons. The policy map generated may include unwanted parameters. Does anyone else have this phone and switch setup that I can use for our new deployment that is tested and proven?
