Configuration Roadmap
The configuration roadmap is as follows:
1. Configure the VLAN for each interface so that the devices can communicate with each
other.
2. Create and configure a DiffServ domain on the Switch, map packets of 802.1p priorities to
PHBs and colors of packets, and bind the DiffServ domain to an incoming interface on the
Switch.
3. Create a WRED drop profile on the Switch and apply the WRED drop profile on an outgoing
interface.
4. Set scheduling parameters of queues of different CoS on outgoing interfaces of the
Switch.
Data Preparation
To complete the configuration, you need the following data:
l VLAN IDs of data packets, video packets, and voice packets, namely, 2, 5, and 6
l PHBs mapped to 802.1p priorities being 6, 5, and 2 and colors
l Name of the WRED drop profile and WRED parameters
l Scheduling parameters of queues of different CoS
