APPLICATION NOTE - Deploying IP Telephony with EX Series Ethernet Switches

As discussed previously regarding the interaction between LLDP and LLDP-MED, the EX Series will initially advertise its

capabilities using LLDP only, as shown in Figure 7. The LLDP-MED-capable phone will advertise its capabilities using

LLDP-MED, as shown in Figure 8. A Cisco IP phone 7945G was used in the following example.

Figure 8: LLDP-MED-capable VoIP phone advertising its capabilities

Sections preceded with a TIA heading show that the VoIP phone is LLDP-MED-capable; its media capabilities and

network policy can also be viewed. Note that the VLAN ID sent by the VoIP phone shows the voice VLAN ID as 0 with a

Layer 2 (802.1p) priority of 5 for voice traffic and a VLAN ID of 0 with a Layer 2 (802.1p) priority of 4 for voice-signaling

traffic.
