QoS with VLAN

Non-VLAN IP Packet Routed Out a Fast/GigabitEthernet Interface

In this scenario, shown in
FastEthernet 1.1. Since the input IP DSCP was 46 it will match the class matchDscp. The output
VLAN frame will be marked with a priority of 4.

QoS with VLAN Configuration Process

Follow the steps below to configure the XSR for QoS with VLAN routing.
1. Configure a sub-interface.
interface <Interface name> <slot/card/number>
2. Stipulate a VLAN ID on the sub-interface.
vlan <number>
3. Specify an IP address on a sub-interface.
ip address <IP address> <mask>
4. Add a traffic class.
class-map <match-all | match-any> <class-map name>
5. Match the IEEE 802.1 priority in the input VLAN header.
match cos <0 - 7>
