Note:
Note: When you reboot a deskphone to enable 802.1x, enable 802.1x on the switch
only when the deskphone completes the rebooting procedure and shows the
login prompt or is already logged in.
About Link Layer Discovery Protocol (LLDP)
Link Layer Discovery Protocol (LLDP) is an open standards layer 2 protocol that IP Telephones
use to advertise their identity and capabilities and to receive administration from an LLDP
server. LAN equipment can use LLDP to manage power, administer VLANs, and provide some
administration.
The transmission and reception of LLDP is specified in IEEE 802.1AB-2005. The 9600 Series
IP Telephones use Type-Length-Value (TLV) elements specified in IEEE 802.1AB-2005, TIA
TR-41 Committee - Media Endpoint Discovery (LLDP-MED, ANSI/TIA-1057), and Proprietary
elements. LLDP Data Units (LLDPDUs) are sent to the LLDP Multicast MAC address
(01:80:c2:00:00:0e).
9600 Series IP Deskphones running SIP software support IEEE 802.1AB if the value of the
configuration parameter LLDP_ENABLED is "1" (On) or "2" (Auto). If the value of
LLDP_ENABLED is “0” (off), the transmission and reception of Link Layer Discovery Protocol
(LLDP) is not supported. When the value of LLDP_ENABLED is “2”, the transmission of LLDP
frames will not begin until or unless an LLDP frame is received, and the first LLDP frame will be
transmitted within 2 seconds after the first LLDP frame is received. Once transmission begins,
an LLDPDU will be transmitted every 30 seconds.
Note:
Note: There could be a delay of up to 30 seconds in deskphone initialization if the file
server address is delivered by LLDP and not by DHCP.
These deskphones:
● Do not support LLDP on the secondary Ethernet interface.
● Will not forward frames received with the 802.1AB LLDP group multicast address as the
destination MAC address between the Ethernet line interface and the secondary Ethernet
interface.
A 9600 Series IP deskphone initiates LLDP after receiving an LLDPDU message from an
appropriate system. Once initiated, the deskphones send an LLDPDU every 30 seconds with
the contents described in LLDPDU transmitted by SIP Deskphones.
