Diffserv and 802.1p - Matching/Interworking
Firstly, lets make sure that I've understood the manual correctly.
The media-policy attribute for a realm ONLY configures the tos-values for the RTP?
The class-profile attribute must be configured with a media-policy that matches message/sip in order for my SBC to set DSCP for my SIP traffic?
But I can actually define a single media policy, used by both media-policy attribute, and class profile? :-O
Hopefully I havent missunderstood anything major anyway.
The follow-on question becomes:
Once the packet has been "dscp-stamped", and is then sent over a vlan-tagged link; what is the values of the 802.1p priority field? Browsing through the manual, I cant even find a reference to 802.1p.
