Glossary

The following figure illustrates the actions performed on three different bridged traffic flows (that is

VoIP, video conference, and email) at access and core ports throughout the network.

Figure 60: Trusted bridged traffic

For bridged, untrusted traffic, if you configure the port to access, mark and prioritize traffic on the

access node using global filters. Reclassify the traffic to ensure it complies with the class of service

specified in the SLA.

For Resilient Packet Ring (RPR) interworking, you can assume that, for all incoming traffic, the QoS

configuration is properly marked by the access nodes. The core switch ports, configured as core or

trunk ports, perform the RPR interworking. These ports preserve the DSCP marking and re-mark the

802.1p bit to match the 802.1p bit of the RPR. The following figure shows the actions performed on

three different traffic flows (VoIP, video conference, and email) over an RPR core network.
