Type 127 IEEE 802.3 Organizationally Specific TLVs 127 127 127 127 TLV Protocol Identity Description Indicates the protocols that the port can process. The Dell Networking OS does not currently support this TLV. MAC/PHY Configuration/Status Power via MDI Link Aggregation Maximum Frame Size 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 Dell Networking OS implementation of LLDP, but is available and mandatory (non-configurable) in the LLDP-MED implementation. Dell Networking supports the LLDP-MED protocol, which recommends that Power via MDI TLV be not implemented, and therefore Dell Networking implements Extended Power via MDI TLV only. Indicates whether the link is capable of being aggregated, whether it is currently in a LAG, and the port identification of the LAG. The Dell Networking OS does not currently support this TLV. Indicates the maximum frame size capability of the MAC and PHY. 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 Networking system is an LLDP-MED network connectivity device. 612 Link Layer Discovery Protocol (LLDP)
