to your network. For example, your call control system may require a particular
voice VLAN ID.

CDP & LLDP
Device discovery protocols enable directly connected devices to discover
information about each other. You may wish to enable these protocols to allow
your network management system to learn about your ATA and endpoints. Use the
Network Setup > Advanced Settings > CDP & LLDP page to specify the settings
for Cisco Discovery Protocol (CDP) and the Link Layer Discovery Protocol (LLDP).
When a discovery protocol is enabled, the ATA sends periodic messages to a
multicast address and also listens to the periodic messages sent by other devices
that use that protocol.
After making changes, click Submit to save your settings, or click Cancel to
redisplay the page with the saved settings.
