LLDP-MED advertises VLAN, dot1P, and DSCP configurations on the switch so that you do not need to manually configure every phone with this information. Refer to Chapter 29, Link Layer Discovery Protocol. Based on the configuration in the example below, the phone will initiate a DHCP request on the advertised voice VLAN, VLAN 200.

Refer to Chapter 44, Quality of Service. Honor the incoming DSCP value On both the C-Series or S-Series, if you know traffic originating from the phone is tagged with the DSCP value of 46 (EF), you might make the associated queue a strict priority queue, as shown in the example below; on the C-Series and S-Series, FTOS maps DSCP 46 to queue 2 (refer to (Table 44-5) in the QoS chapter.)
