In the tunneling configuration, you can use ACL lists and QoS parameters to ensure that time-sensitive traffic, such as VoIP,
takes priority over other WLAN traffic.
For many IP phone systems, you must connect a call server to a wired port on the L3 tunnel subnet. You must also either
configure DHCP relay on the switch or configure the switch to be a DHCP server. APs, peer switches, and other routers
cannot be connected to the L3 tunnel subnet.
For more information about L3 tunnelling and how to configure it, see
Appendix Appendix C:, <Link>"L3 Roaming Example" on page 213.
