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 802based 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 premisesbased 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. 13-38
