1.6.2 Example for Re-marking the Priorities Based on Complex
Traffic Classification
After priority re-marking based on complex traffic classification is configured, the S7700 adds
the same outer VLAN ID to packets with different VLAN IDs. That is, these packets are
uniformly taken as the service data. In addition, the S7700 re-marks different 802.1p priorities
of packets with different VLAN IDs to provide differentiated services.
Networking Requirements
The Switch is connected to the router through GE2/0/1 ; branch 1 and branch 2 of the enterprise
can access the network through the Switch and router. See
Data services of branch 1 and branch 2 of the enterprise come from VLANs 100 and 200. When
the data service packets of branch 1 and branch 2 of the enterprise pass the Switch, the Switch
needs to add the outer VLAN tag with the VLAN 300 to the packets so that these packets are
identified as data services on the Core network. In addition, branch 1 require better QoS
guarantee; therefore, the priority of data packets to branch 1 is mapped to 4 and the priority of
data packets to branch 2 is mapped to 2. By doing this, differentiated services are provided.
