10.6.2.2 QoS & VLAN
On the webpage, go to [Network] >> [Advance]. Here, you can configure:
◼ LLDP
Link Layer Discovery Protocol. LLDP is a vendor-independent link layer protocol used by network devices
for advertising their identity and capabilities to neighbors on a LAN segment.
The telephone can use LLDP to find the VLAN switch or other VLAN devices and use the LLDP learning
feature to apply the VLAN ID from the VLAN switch to the telephone itself.
◼ CDP
Cisco Discovery Protocol. CDP is a not-for-profit charity that runs the global disclosure system for investors,
companies, cities, states and regions to manage their environmental impacts. According to CDP, Cisco
devices could share OS version, IP address, hardware version and so on.

10.6.2.3 VPN
A Virtual Private Network (VPN) is a technology that allows a device to create a tunneling connection to a
server and becomes part of the server’s network. The network transmission of the device may be routed
through the VPN server.
For some users, especially business users, a VPN connection might have to be established before
activating a line registration. The device supports two VPN modes, Layer 2 Transportation Protocol (L2TP)
and OpenVPN.
The VPN connection must be configured and started (or stopped) from the device web portal.
