Creating VLANs <strong>for</strong> an Office VOIP Deployment<br />

The phone requires one tagged VLAN <strong>for</strong> VOIP service and one untagged VLAN <strong>for</strong> PC data, as shown in<br />

Figure 456. You may configure voice signaling on <strong>the</strong> voice VLAN, but some implementations might need<br />

an additional tagged VLAN <strong>for</strong> this traffic; Figure 457 adds an additional tagged VLAN <strong>for</strong> voice<br />

signaling. The example is from a C-<strong>Series</strong>, but an S-<strong>Series</strong> would be configured in <strong>the</strong> same way.<br />

Configuring LLDP-MED <strong>for</strong> an Office VOIP Deployment<br />

VOIP deployments may optionally use LLDP-MED. LLDP-MED advertises VLAN, dot1P, and DSCP<br />

configurations on <strong>the</strong> switch so that you do not need to manually configure every phone with this<br />

in<strong>for</strong>mation. See Chapter 14, Link Layer Discovery Protocol. Based on <strong>the</strong> configuration in Figure 458,<br />

<strong>the</strong> phone will initiate a DHCP request on <strong>the</strong> advertised voice VLAN, VLAN 200.<br />
