static.network.lldp.packet_interval

It configures the interval (in seconds) that how often the IP phone sends the LLDP
(Linker Layer Discovery Protocol) request.
Note: It works only if “static.network.lldp.enable” is set to 1 (Enabled).

If you change this parameter, the IP phone will reboot to make the change take effect.
CDP Configuration
CDP (Cisco Discovery Protocol) allows IP phones to receive and/or transmit device-related information
from/to directly connected devices on the network that are also using the protocol, and store the
information about other devices.
If the CDP feature is enabled on IP phones, the IP phones will periodically advertise their own information
to the directly connected CDP-enabled switch. The IP phones can also receive CDP packets from the
connected switch. If the VLAN configurations on the IP phones are different from the ones sent by the
switch, the IP phones will perform an update and reboot. This allows you to connect the IP phones into
any switch, obtain their VLAN IDs, and then start communications with the call control.
The following table lists the parameters you can use to configure CDP.
static.network.cdp.enable
[1]
It enables or disables the CDP (Cisco Discovery Protocol) feature on the IP phone.
0-Disabled
1-Enabled, the IP phone will attempt to determine its VLAN ID through CDP.
