Enabling LLDP polling
With LLDP polling enabled, a device periodically searches for local configuration changes. On detecting
a configuration change, the device sends LLDPDUs to inform neighboring devices of the change.
To enable LLDP polling:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
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:
port-group manual
port-group-name
Use either command.
3.
Enable LLDP polling and
set the polling interval.
lldp check-change-interval
interval
Disabled by default.
Configuring the advertisable TLVs
To configure the advertisable LLDPDU TLVs on the specified port or ports:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
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:
port-group manual
port-group-name
Use either command.
3.
Configure the
advertisable TLVs (Layer
2 Ethernet interface view
or port group view).

TLVs except location
identification TLVs are
advertisable on a Layer 2
Ethernet port.

By default, all types of LLDP
TLVs, except IEEE 802.1
organizationally specific
TLVs, network policy TLVs,
and location identification
TLVs, are advertisable on a
Layer 3 Ethernet port.
