R3303-HP HSR6800 Routers Layer 2 - LAN Switching Configuration Guide

207
NOTE:
• The router supports only receiving protocol identity TLVs and does not support DCBX TLVs.
• Layer 3 Ethernet ports do not support IEEE 802.1 organizationally specific TLVs.

MAC/PHY Configuration/Status
Contains the bit-rate and duplex capabilities of the sending port,
support for auto negotiation, enabling status of auto negotiation, and
the current rate and duplex mode.
Power Via MDI
Contains the power supply capability of the port, including the Power
PoE type (which can be PSE or PD), PoE mode, whether PSE power
supply is supported, whether PSE power supply is enabled, and
whether the PoE mode is controllable.
Link Aggregation
Indicates the aggregation capability of the port (whether the link can
be aggregated), and the aggregation status (whether the link is in an
aggregation).
Maximum Frame Size
Indicates the supported maximum frame size. It is now the MTU of the
port.
Power Stateful Control
Indicates the power state control configured on the sending port,
including the power type of the PSE/PD, PoE sourcing/receiving
priority, and PoE sourcing/receiving power.
NOTE:
The power stateful control TLV is defined in IEEE P802.3at D1.0. Later versions no lon
g
er support this TLV.
HP devices send this type of TLV only after receiving them.
4. LLDP-MED TLVs
LLDP-MED TLVs provide multiple advanced applications for VoIP, such as basic configuration,
network policy configuration, and address and directory management. LLDP-MED TLVs provide a
cost-effective and easy-to-use solution for deploying voice devices in Ethernet. LLDP-MED TLVs are
shown in Table 25.

LLDP-MED Capabilities
Allows a network device to advertise the LLDP-MED TLVs that it
supports.
Network Policy
Allows a network device or terminal device to advertise the VLAN ID of
the specific port, VLAN type, and Layer 2 and Layer 3 priorities for
specific applications.
Extended Power-via-MDI
Allows a network device or terminal device to advertise power supply
capability. This TLV is an extension of the Power Via MDI TLV.
Hardware Revision Allows a terminal device to advertise its hardware version.
Firmware Revision Allows a terminal device to advertise its firmware version.
Software Revision Allows a terminal device to advertise its software version.
