Conguring LLDP-MED for an Oce VoIP Deployment
VoIP deployments may optionally use LLDP-MED.
LLDP-MED advertises VLAN, dot1P, and DSCP congurations on the switch so that you do not need to manually congure 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
protocol lldp
advertise med
advertise med voice 200 6 46
advertise med voice-signaling 300 5 28
no disable

Conguring QoS for an Oce VoIP Deployment
There are several ways you can use quality of service (QoS) to map ingress phone and PC trac to give them each a dierent quality of
service.
Honoring the Incoming DSCP Value
If you know that trac 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
