- To allows the XSR to forward tagged packets and provide QoS based on the P bit, the XSR is Q-trunk aware as of firmware 18.104.22.168
- The XSR will not switch between interfaces and forwards only packets that need to be routed. The configuration is a matter of assigning a VLAN to each routed (sub-)interface, with VLAN-tagging assumed.
- The following example configures a FastEthernet sub-interface with VLAN ID 10:
XSR(config)#interface fastethernet 2.1
XSR(config-if<f2.1>)#ip address 22.214.171.124 255.255.255.0
