Microsoft Lync Edition Administrator's Guide for SIP-T2_Series and T4_Series IP Phones
When CDP feature is enabled on IP phones, the IP phones periodically advertise their
own information to the directly connected CDP-enabled switch. The IP phones can also
receive CDP packets from the connected switch. 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.
