Figure 36-8.  Creating VLANs for an Office VOIP Deployment
Configure LLDP-MED for an Office VOIP Deployment
VOIP deployments may optionally use LLDP-MED. 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. See Chapter 26, Link Layer Discovery Protocol. Based on the configuration in Figure 36-9, 
the phone will initiate a DHCP request on the advertised voice VLAN, VLAN 200.
