Table 38. Optional TLV Types (continued)
Type TLV Description
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. The 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 VLAN Name Indicates the user-defined alphanumeric
string that identifies the VLAN.
127 Protocol Identity Indicates the protocols that the port can
process. The 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. 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.
Link Layer Discovery Protocol (LLDP) 451
