Type TLV Description127 Protocol Identity Indicates the protocols that theport can process. DellNetworking OS does notcurrently support this TLV.IEEE 802.3 OrganizationallySpecific TLVs127 MAC/PHY Configuration/Status Indicates the capability andcurrent setting of the duplexstatus and bit rate, and whetherthe current settings are the resultof auto-negotiation. This TLV isnot available in the DellNetworking OS implementationof LLDP, but is available andmandatory (non-configurable) inthe LLDP-MED implementation.127 Power via MDI Dell Networking supports theLLDP-MED protocol, whichrecommends that Power via MDITLV be not implemented, andtherefore Dell Networkingimplements Extended Power viaMDI TLV only.127 Link Aggregation Indicates whether the link iscapable of being aggregated,whether it is currently in a LAG,and the port identification of theLAG. Dell Networking OS doesnot currently support this TLV.127 Maximum Frame Size Indicates the maximum framesize capability of the MAC andPHY.TIA-1057 (LLDP-MED) OverviewLink 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 connectivitydevices can advertise their characteristics and configuration information; the OUI for theTelecommunications Industry Association (TIA) is 00-12-BB.• LLDP-MED Endpoint Device — any device that is on an IEEE 802 LAN network edge cancommunicate using IP and uses the LLDP-MED framework.• LLDP-MED Network Connectivity Device — any device that provides access to an IEEE 802 LAN to anLLDP-MED endpoint device and supports IEEE 802.1AB (LLDP) and TIA-1057 (LLDP-MED). The DellNetworking system is an LLDP-MED network connectivity device.Link Layer Discovery Protocol (LLDP) 529
