CDP Configuration
CDP (Cisco Discovery Protocol) allows the phones to receive and/or transmit device-related information from/to dir-
ectly connected devices on the local network.
When CDP feature is enabled on the phones, the phones periodically advertise their own information to the directly
connected CDP-enabled switch. The phones can also receive CDP packets from the connected switch and obtain
their VLAN IDs.
The following table lists the parameters you can use to configure CDP.
