Deployment Guide
Type TLV Description
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-
congurable) in the LLDP-MED
implementation.
127 Power via MDI 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.
127 Link Aggregation Indicates whether the link is capable of
being aggregated, whether it is currently in a
LAG, and the port identication of the LAG.
The Dell Networking OS does not currently
support this TLV.
127 Maximum Frame Size Indicates the maximum frame size capability
of the MAC and PHY.
LLDP-MED Capabilities TLV
The LLDP-MED capabilities TLV communicates the types of TLVs that the endpoint device and the network connectivity device support.
LLDP-MED network connectivity devices must transmit the Network Policies TLV.
• The value of the LLDP-MED capabilities eld in the TLV is a 2–octet bitmap, each bit represents an LLDP-MED capability (as shown in
the following table).
• The possible values of the LLDP-MED device type are shown in the following. The Dell Networking system is a network connectivity
device, which is Type 4.
When you enable LLDP-MED in Dell Networking OS (using the advertise med command), the system begins transmitting this TLV.
