I am new to QOS and want to configure switches properly for my implementation. I am installing a Shoretel phone system and am planning on segmenting a Voice VLAN with the "voice" option enabled. I'm not sure if it's priority 6 or 7, as the setting or if it even matters. I understand 802.1p is Layer 2 only and in order to maintain QOS settings over layer 3, there has to be some sort of DSCP map that takes place. I've read the advanced traffic guide and I'm having a hard time determining what needs to be done. I've added a basic diagram that resembles my network. Core switch is 8600 and clients are 2910s. Thanks for all the help.
