Type TLV Description
Networking OS does not
currently support this TLV.
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 Dell
Networking OS implementation
of LLDP, but is available and
mandatory (non-configurable) 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 identification 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 field 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.
