ShoreTel 9.1 Page 73
LLDP / 802.1x
Introduction
Version 9 enhances ShorePhones to support LLDP-MED and 802.1x.
The Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) is an
enhancement to the Link Layer Discovery Protocol (LLDP) that addresses the following:
• Device location discovery to support location databases and VoIP E911 services.
• Auto-discovery of LAN policies to support “plug and play” networking.
• Extended and automated power management of PoE endpoints.
• Inventory management.
A component of IEEE 802.1 group of networking protocols, 802.1x addresses port-based
Network Access Control. It provides an authentication mechanism for devices attaching to
a LAN port to either establish a point-to-point connection or prevent the device from
accessing the port if authentication fails. 802.1x is based on the Extensible Authentication
Protocol (EAP).
Refer to the Glossary for a definition of the following terms used in this release note:
• 802.1x
• LLDP-MED
LLDP-MED
LLDP-MED, an enhancement to the basic LLDP protocol, addresses the discovery of
endpoints by networks supporting LLDP.
Implementing LLDP-MED requires LLDP-MED capable network switches. ShorePhones
IP110 and IP210 do not support LLDP-MED.
Feature Description
ShorePhones that are updated to ShoreTel 9 comply with all mandatory TIA-1057 LLDP-
Med functionality for Class III Communications Device Endpoints and selected optional
capabilities or limitations.
Implementation
ShoreTel changes that support LLDP-MED implementation include the following:
• Definition of a new telephone parameter – LldpEnable
LldpEnable is a one character ASCII parameter. Valid settings for LldpEnable are 0 and
1:
— LldpEnable = 1 (LLDP is enabled)
— LldpEnable = 0 (LLDP is disabled)
Default value is 1 (enabled)
• Modify Setup Source Preferences
When setting up ShorePhones, parameter settings are obtained from the following
sources, listed in order of highest to lowest precedence:
