Conguring LLDP-MED for an Oce VoIP Deployment
VoIP deployments may optionally use LLDP-MED.
LLDP-MED advertises VLAN, dot1P, and DSCP congurations on the switch so that you do not need to manually congure every phone
with this information. In the following example, the phone initiates a DHCP request on the advertised voice VLAN, VLAN 200.
Dell#show running-config lldp

advertise med
advertise med voice 200 6 46
advertise med voice-signaling 300 5 28

Conguring QoS for an Oce VoIP Deployment
There are several ways you can use quality of service (QoS) to map ingress phone and PC trac to give them each a dierent quality of
service.
Honoring the Incoming DSCP Value
If you know that trac originating from the phone is tagged with the DSCP value of 46 (EF), you can make the associated queue a strict-
priority queue, as shown in the following example.
Dell#show run policy-map-input

policy-map-input HonorDSCP
