Optional TLV Types Type TLV Description IEEE 802.3 Organizationally Specific TLVs 127 MAC/PHY Configuration/Status Indicates the capability and current setting of the duplex status and bit rate, and whether the current settings are the result of auto-negotiation. This TLV is not available in the FTOS implementation of LLDP, but is available and mandatory (non-configurable) in the LLDP-MED implementation. 127 Power via MDI Dell Force10 supports the LLDP-MED protocol, which recommends that Power via MDI TLV is not implemented, and therefore Dell Force10 implements Extended Power via MDI TLV only. 127 Link Aggregation Indicates whether the link is capable of being aggregated, whether it is currently in a LAG, and the port identification of the LAG. FTOS does not currently support this TLV. 127 Maximum Frame Size Detects mis-configurations or incompatibility between two stations with different maximum supported frame sizes. TIA-1057 (LLDP-MED) Overview Link layer discovery protocol-media endpoint discovery (LLDP-MED)-as defined by ANSI/ TIA-1057- provides additional organizationally specific TLVs so that endpoint devices and network connectivity devices can advertise their characteristics and configuration information; the OUI for the Telecommunications Industry Association (TIA) is 00-12-BB. • LLDP-MED Endpoint Device-any device that is on an IEEE 802 LAN network edge can communicate using IP and uses the LLDP-MED framework. • LLDP-MED Network Connectivity Device-any device that provides access to an IEEE 802 LAN to an LLDP-MED endpoint device and supports IEEE 802.1AB (LLDP) and TIA-1057 (LLDP-MED). The Dell Force10 system is an LLDP-MED network connectivity device. With regard to connected endpoint devices, LLDP-MED provides network connectivity devices with the ability to: • manage inventory • manage Power over Ethernet (PoE) • identify physical location • identify network policy LLDP-MED is designed for, but not limited to, voice over IP (VoIP) endpoints. 170 | Link Layer Discovery Protocol (LLDP)
