Can someone please verify that my QoS settings are correct? I'm prioritizing VoIP traffic (DSCP 46/COS5) over a 100Mb Layer 2 metro ethernet line, the phones are all Avaya VoIP phones. The reason I'm asking is that the voice quality is terrible and I think the problem is at the provider and not on my equipment. I verified that VoIP traffic (and only VoIP) has DSCP 46 marking with a packet capture.
I think you are using some kinda template there which you are using in all your switchports and applied the same onto this port as well.
As far as i know once the traffic comes out of L2 to L3 you need to make use of PQ/CBWFQ techniques to prioritize the voice and guarantee bandwidth to other traffic.
Have you negotiated the class maps / QoS policies with your SP, it does matter that your SP honours and carry forward your QoS settings throughout his network and deliver the same @ remote end. Atleast he needs to match your traffic priorities with his internal maps.
Untill otherwise this is there in place you cant expect a quality voice transaction between the locations.
