LLDP Configuration
LLDP (Linker Layer Discovery Protocol) is a vendor-neutral Link Layer protocol, which 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.
When LLDP feature is enabled on IP phones, the IP phones periodically advertise their own information to the directly
connected LLDP-enabled switch. The IP phones can also receive LLDP packets from the connected switch. When the
application type is “voice”, the IP phones decide whether to update the VLAN configurations obtained from the LLDP
packets. When the VLAN configurations on the IP phones are different from the ones sent by the switch, the IP phones
perform an update and reboot. This allows the IP phones to plug 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 LLDP.
Parameter
static.network.lldp.enable
[1]
<y0000000000xx>.cfg
Description
It enables or disables the LLDP (Linker Layer Discovery Protocol) feature on the IP phone.
Permitted Val-
ues
0
-Disabled
1
-Enabled, the IP phone will attempt to determine its VLAN ID through LLDP.
Default
1
Web UI
Network->Advanced->LLDP->Active
Parameter
static.network.lldp.packet_interval
[1]
<y0000000000xx>.cfg
Description
It configures the interval (in seconds) that how often the IP phone sends the LLDP (Linker Layer Dis-
covery Protocol) request.
Note
: It works only if “static.network.lldp.enable” is set to 1 (Enabled).
Permitted Val-
ues
Integer from 1 to 3600
Default
60
Web UI
Network->Advanced->LLDP->Packet Interval (1~3600s)
[1]
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 dir-
ectly 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.
Parameter
static.network.cdp.enable
[1]
<y0000000000xx>.cfg
