 LLDP Enhancements Multiple Neighbor Support: Multiple neighbors are supported on a single LLDP interface. The number of recognized neighbors is limited to two per port or 834 LLDP neighbors on a fully stacked set of switches. There is no restriction on the number of neighbors connected to an LLDP port. If more LLDP neighbors are present than are supported, then only the last two neighbors that communicate with the local LLDP interface are recognized and any additional neighbors are ignored. EEE Support: Support is added to process/communicate the EEE TLV to partner devices. The EEE TLV is an 802.3 organizationally specific TLV used to report on the EEE Data Link Layer capabilities. LLDP-MED Support: LLDP-MED uses LLDP's organizationally specific TLV extensions and defines new TLVs which make it easier to deploy VoIP in a wired or wireless LAN/MAN environment. The LLDP implementation supports the following TLVs: Mandatory 802.1AB TLVs  Chassis ID TLV (subtype shall default to MAC Address)  Port ID TLV (subtype shall default to MAC address  TTL TLV  MAC/PHY configuration/status TLV  End of LLDP PDU Optional 802.1AB TLV  Systems Capabilities TLV  Power via MDI TLV NOT recommended for transmission in order to conserve LLDPDU space. Mandatory LLDP-MED TLVs  LLDP-MED Capabilities TLV This TLV allows the network connectivity device to definitively determine whether particular connected devices do support LLDP-MED and to discover which specific LLDP-MED TLVs the particular end point devices are capable of supporting as well as what specific device class they belong to.  Network Policy TLV This TLV allows the device to advertise its VLAN and associated Layer 2 priority and Layer 3 DSCP attributes which apply for a set of specific protocol applications on this port.  Location Identification TLV This TLV provides the advertisement of location identifier information Class II endpoint Devices. This is expected to be related to wire map or similar network topology data, such that the configuration of the network Connectivity device is able to uniquely identify the physical location of the connected MED endpoint.  Extended Power-via-MDI TLV This TLV allows for advanced power management between endpoints and network connectivity devices. It transmits fine grained power requirement details. This TLV provides significantly more value than the 802.1AB Power via MDI TLV.  EEE TLV The EEE TLV is used to exchange information about the EEE Data Link Layer capabilities. Devices that require longer wake up times prior to being able to accept data on their receive paths may use the Data Link Layer capabilities to negotiate for extended system wake up times from the transmitting link partner. This mechanism may allow for more or less aggressive energy saving modes. 14 System Firmware Version 4.1.0.6
