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”,
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 be plugged into any switch, obtain their VLAN IDs, and then start
communications with the call control.
