Managing Cisco Discovery Protocol
The
Cisco Discovery Protocol
(CDP) is a Cisco proprietary protocol that enables
devices to advertise their existence to other devices by CDP sending out periodic
updates to a Multicast address. In addition, CDP allows devices to receive
information about other devices on the same LAN or on the remote WAN side. The
system supports CDP versions 1 and 2. To enable CDP on the device:
STEP 1
Click Monitor & Device Properties > CDP. The
CDP Page
opens:
CDP Page
The
CDP Page
contains the following fields:
•
CDP Status
— Indicates if CDP is enabled on the device. The possible field
values are:
-
Enable
— Enables CDP on the device. This is the default value.
-
Disable
— Disables CDP on the device.
•
Voice VLAN
— Indicates the VLAN ID advertised by the device. The Voice
VLAN is advertised when a local 802.1Q interface has been configured to
send and receive VoIP packets. The field default value is 100.
