Chapter 55 Configuring a VoIP Network

Understanding How CDP and VoIP Work

Understanding How CDP and VoIP Work

Cisco Discovery Protocol (CDP) was enhanced in software release 8.1(1) to facilitate backward compatibility with the newer, higher-powered Cisco IP phones. With this enhanced CDP, a Cisco IP phone can negotiate its power requirements to the switch within the CDP packet. The switch uses this information to ensure that it does not oversubscribe the available power.

We recommend that you enable CDP on the switch so that the switch can correctly detect and supply power to the IP phones that are connected to it. CDP is enabled on the Catalyst 6500 series switches by default; however, you should confirm that CDP is enabled when setting up your VoIP network. For more information on CDP, see Chapter 31, “Configuring CDP.”

Configuring VoIP on a Switch

This section describes the command-line interface (CLI) commands and the procedures that are used to configure the Catalyst 6500 series switch for VoIP operation:

•Voice-Related CLI Commands, page 55-10

•Configuring Per-Port Power Management, page 55-11

•Configuring the Auxiliary VLANs on Catalyst LAN Switches, page 55-20

•Configuring the Access Gateways, page 55-23

•Displaying the Active Call Information, page 55-29

•Configuring QoS in the Cisco IP Phone 7960, page 55-31

•Configuring a Trusted Boundary to Ensure Port Security, page 55-33

Note For information on using automatic voice configuration, see the “Using SmartPorts” section on page 55-38.

Note You must enable CDP on the Catalyst 6500 series switch port that is connected to the IP phone in order to communicate the auxiliary VLAN ID, per-port power management details, and quality of service (QoS) configuration information.
