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

In this scenario, shown in Figure 12-5, the policy map setCos4 is applied to the output interface 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>
