Configuring for Network Management Applications
LLDP (Link-Layer Discovery Protocol)
LLDP Neighbor: An LLDP device that is either directly connected to another
LLDP device or connected to that device by another, non-LLDP Layer 2 device
(such as a hub) Note that an 802.1D-compliant switch does not forward LLDP
data packets even if it is not LLDP-aware.
LLDPDU (LLDP Data Unit): LLDP data packet are transmitted on active
links and include multiple TLVs containing global and per-port switch
information. In this guide, LLDPDUs are termed “advertisements” or
“packets”.
LLDP-MED (Link Layer Discover Protocol Media Endpoint
Discovery): The TIA telecommunications standard produced by engineering
subcommittee TR41.4, “VoIP Systems — IP Telephony infrastructure and
Endpoints” to address needs related to deploying VoIP equipment in IEEE 802-
based environments. This standard will be published as ANSI/TIA-1057.
MIB (Management Information Base): An internal database the switch
maintains for configuration and performance information.
MLTS (Multiline Telephone System): A network-based and/or premises-
based telephone system having a common interface with the public switched
telephone system and having multiple telephone lines, common control units,
multiple telephone sets, and control hardware and software.
NANP (North American Numbering Plan): A ten-digit telephone number
format where the first three digits are an area code and the last seven-digits
are a local telephone number.
Neighbor: See “LLDP Neighbor”.
Non-LLDP Device: A device that is not capable of LLDP operation.
PD (Powered Device): This is an IEEE 802.3af-compliant device that
receives its power through a direct connection to a 10/100Base-TX PoE RJ-45
port in a ProCurve fixed-port or chassis-based switch. Examples of PDs
include Voice-over-IP (VoIP) telephones, wireless access points, and remote
video cameras.
PSAP (Public Safety Answering Point): PSAPs are typically emergency
telephone facilities established as a first point to receive emergency (911) calls
and to dispatch emergency response services such as police, fire and
emergency medical services.
PSE (Power-Sourcing Equipment): A PSE, such as a PoE module installed
in a switch covered in this guide, provides power to IEEE 802.3af-compliant
PDs directly connected to the ports on the module.
