IEEE Organizationally Specific TLVs
Eight TLV types have been defined by the IEEE 802.1 and 802.3 working groups (Table 30-2) 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 30-2. 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 describes 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 VLAN Name Indicates the user-defined alphanumeric string that identifies the VLAN. This
TLV is supported on C-Series only.
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 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.
127 Maximum Frame Size Indicates the maximum frame size capability of the MAC and PHY
