Configuring LLDP Configuration Example 6.2 Example for Configuring LLDP-MED 6.2.1 Network Requirements The marketing department needs establish the voice conversation with the field office. They want to install IP phones in their office and meet the following requirements: Save the switch ports for more IP phones due to the limited number of the ports on the switch in the office; The voice traffic is transmitted in a separate VLAN to guarantee the voice quality. The IP phones can finish the Voice VLAN configuration automatically to minimize the configuration effort. 6.2.2 Configuration Scheme To save the limited ports on the switch, connect the IP phone and the PC in a series, then the IP phone and PC can share the same port on the switch. Configure LLDP-MED to work together with Voice VLAN to guarantee the voice quality and reduce the configuration effort. Configure the port which the IP phone is connected with, then IP phone can automatically finish its Voice VLAN configuration using the received LLDP-MED packets and send tagged voice packets to the switch. Voice packets will be transmitted in the Voice VLAN while other traffic will be transmitted in the default VLAN. Please note that the PVID of the port which the IP phone is connected with cannot be the same as the VLAN ID of the Voice VLAN. Refer to Configuring Voice VLAN for detailed instructions. 6.2.3 Network Topology Exampled with the configuration of one IP phone: One end of the IP phone is connected to the PC, the other end is connect to port Gi1/0/1 on the switch. Port Gi1/0/2 on the switch is connect to the voice gateway. Figure 6-4 LLDP-MED Network Topology Gi1/0/1 Gi1/0/2 PC IP: 172.168.1.222 IP Phone Switch A Voice Gateway To ensure the voice traffic can be preferentially treated, configure the corresponding settings on each device in the link. Demonstrated with T2600G-28TS, this section provides configuration procedures in two ways: using the GUI and using the CLI. Configuration Guide 870
