Huawei quidway s7700 - Networking Requirements

Networking Requirements
The Switch is connected to the router by using GE 2/0/1; enterprise users can access the network
by using the Switch and the router. See Table 2-2.
l Voice services of the enterprise belong to VLAN 120.
l Video services of the enterprise belong to VLAN 110.
l Data services of the enterprise belong to VLAN 100.
On the Switch, traffic policing needs to be performed on packets of different services to limit
traffic within a proper range and ensure bandwidth of each service.
DSCP priorities carried in service packets sent from the user side cannot be trusted and services
require different QoS in practice. Therefore, you need to re-mark DSCP priorities of different
service packets on the Switch so that the downstream router can process packets based on
priorities.
The requirements are as follows:
Table 2-2 QoS provided by the Switch for upstream traffic
Traffic Type CIR (Mbit/s) PIR (Mbit/s) DSCP Priority
Voice 2 10 46
Video 4 10 30
Data 4 10 14
