Optional) Configuring The Tlv In The Lldpdu - Huawei Quidway S5700 Series Configuration Manual - Network Management

Quidway S5700 Series Ethernet Switches
Configuration Guide - Network Management
Prerequisite
LLDP has been enabled globally.
Context
If the configured management address is invalid or no management address is configured, the
system sets an IP address in the address list as the management address. The system selects the
IP address in the following priority order: loopback interface address, console port address, and
then VLANIF interface address. Among the IP addresses of the same type, the system selects
the smallest one. If the system does not find a management address, the bridge MAC address is
used as the management address.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
lldp management-address ip-address
The LLDP management address is configured.
The value of ip-address must be a valid unicast IP address existing on the device. Using the IP
address of the console port as the LLDP management address is recommended.

2.3.5 (Optional) Configuring the TLV in the LLDPDU

The LLDPDUs contain different types of TLVs. The devices send and receive device
information by using these TLVs. The TLVs that can be encapsulated in an LLDP packet include
basic TLVs, organizationally specific TLVs, and TLVs related to media endpoint discovery
(MED).

Context
To enable an interface to send the 802.3 Power via MDI TLV, run the lldp tlv-enable dot3-tlv
power command. The 802.3 Power via MDI TLV has the following formats:
l
l
Based on 802.1ab, 802.3at extends three fields: type/source/priority, PD requested power value,
and PSE allocated power value.
