We have several 6224's running on a Layer 2 backbone provider's network. We are in the beginning stages of implementing an Avaya telephone upgrade which will require me to dig in and properly ensure all QOS is applied as needed. The Avaya vendor is indicating a DSCP 46 with a COS of 5 on it's network diagrams which I'm assuming is referring to a DIFF SERV configuration.
At this point, I've not yet touched anything within the QOS of each switch and it appears as if each switch is default configured for 802.1p TRUST MODE. Has anyone worked with the QOS particularly in VOIP applications? If so...can you share your Best practices and or give tips on proper configuration of each switch.
I've got each VOIP / VLAN 2 port identified. Each switch has a Layer 3 Routing table applied as well as all VLAN's have routing applied to create the Fully routable network.
