IEEE Organizationally Specific TLVs
Eight TLV types have been defined by the IEEE 802.1 and 802.3 working groups as a basic part of LLDP; the IEEE OUI is 00-80-C2. You
can configure the Dell Networking system to advertise any or all of these TLVs.
Table 50. Optional TLV Types
Type TLV Description
Optional TLVs
4 Port description A user-defined alphanumeric string that
describes the port. Dell Networking OS
does not currently support this TLV.
5 System name A user-defined alphanumeric string that
identifies the system.
6 System description A user-defined alphanumeric string that
identifies the system.
7 System capabilities Identifies the chassis as one or more of the
following: repeater, bridge, WLAN Access
Point, Router, Telephone, DOCSIS cable
device, end station only, or other.
8 Management address Indicates the network address of the
management interface. Dell Networking OS
does not currently support this TLV.
IEEE 802.1 Organizationally Specific
TLVs
127 Port-VLAN ID On Dell Networking systems, indicates the
untagged VLAN to which a port belongs.
127 Port and Protocol VLAN ID On Dell Networking systems, indicates the
tagged VLAN to which a port belongs (and
the untagged VLAN to which a port belongs
if the port is in Hybrid mode).
127 Protocol Identity Indicates the protocols that the port can
process. Dell 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. Dell Networking OS does not currently
support this TLV.
