Configuring LLDP 
Overview 
Background 
In a heterogeneous network, a standard configuration exchange platform ensures that different types of 
network devices from different vendors can discover  one another and exchange configuration for the 
sake of interoperability and management.  
The IETF drafted the Link Layer Discovery Protocol (LLDP) in IEEE 802.1AB. The protocol operates on the 
data link layer to exchange device information between directly connected devices. With LLDP, a device 
sends...

 222 
Field Description 
Source MAC address MAC address of the sending port. If the port does not have a MAC address, 
the MAC address of the sending bridge is used.  
Type 
Ethernet type for the upper layer protocol. It is 0x88CC for LLDP.  
Data LLDPDU. 
FCS  Frame check sequence, a 32-bit CRC valu
e used to determine the validity of 
the received Ethernet frame.

TLVs 
TLVs are type, length, and value sequences that carry information elements. The type field identifies the 
type of information, the length field measures the le ngth of the information field in octets, and the value 
field contains the information itself.  
LLDPDU TLVs fall into the following categories:  
•   Basic management TLVs 
•   Organizationally (IEEE 802.1 and IEEE 802.3) specific TLVs 
•   LLDP-MED (media endpoint discovery) TLVs 
Basic management TLVs are essential to device...

 224 
Type Description 
VLAN Name Specifies the textual name of any VLAN 
to which the port belongs. An LLDPDU 
can carry multiple different TLVs of this type. 
Protocol Identity  Indicates protocols supported on the 
port. An LLDPDU can carry multiple 
different TLVs of this type. 
 
  NOTE: 
•  HP devices support only receiving protocol identity TLVs. 
•   Layer 3 Ethernet ports do not support IEEE 802.1 organizationally specific TLVs.

•  A new neighbor is discovered. A new LLDPDU is received and carries device information new to the 
local device.  
•   The LLDP operating mode of the port changes from Disable or Rx to TxRx or Tx.  
This is the fast sending mechanism of LLDP. With this  me chani s m, a  spe ci fic  nu mber  of  L L D PD Us  are  sent 
successively at 1-second inter vals, to help LLDP neighbors discover the local device as soon as possible. 
Then, the normal LLDPDU transmit interval resumes.

Performing basic LLDP configuration 
Enabling LLDP 
To make LLDP take effect on specific ports, you must enable LLDP both globally and on these ports.  
To enable LLDP: 
 
Step Command Remarks 
1.  Enter system view. 
system-view  N/A 
2.  Enable LLDP globally. 
lldp enable  By default, LLDP is globally 
enabled. 
3.
  Enter Ethernet interface 
view or port group view. 
• Enter Layer 2/Layer 3 Ethernet interface 
view: 
interface interface-type interface-number
 
• Enter port group view:...

 228 
To set the LLDP re-initialization delay for ports:  
Step Command Remarks 
1.  Enter system view. 
system-view  N/A 
2.  Set the LLDP re-initialization 
delay.  lldp timer reinit-delay
 delay   Optional. 
2 seconds by default. 
 
Enabling LLDP polling 
With LLDP polling enabled, a device periodically sear
ches for local configuration changes. On detecting 
a configuration change, the device sends LLDPDUs to inform neighboring devices of the change. 
To enable LLDP polling:
