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
By default, LLDP polling is
disabled.
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 or 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 in Layer 2 Ethernet
interface view or port group
view.
lldp tlv-enable { basic-tlv { all |
port-description | system-capability |
system-description | system-name } |
dot1-tlv { all | port-vlan-id | protocol-vlan-id
[ vlan-id ] | vlan-name [ vlan-id ] } | dot3-tlv
{ all | link-aggregation | mac-physic |
max-frame-size | power } | med-tlv { all |
capability | inventory | location-id
{ civic-address device-type country-code
{ ca-type ca-value }&<1–10> | elin-address
tel-number } | network-policy |
power-over-ethernet } }
Optional.
By default, all types of
LLDP TLVs except location
identification TLVs are
advertisable on a Layer 2
Ethernet port.
4. Configure the advertisable
TLVs in Layer 3 Ethernet
interface view.
lldp tlv-enable { basic-tlv { all |
port-description | system-capability |
system-description | system-name } |
dot3-tlv { all | link-aggregation | mac-physic
| max-frame-size | power } | med-tlv { all |
capability | inventory | location-id
{ civic-address device-type country-code
{ ca-type ca-value }&<1-10> | elin-address
tel-number } | power-over-ethernet } }
Optional.
By default, all types of
LLDP TLVs, except the IEEE
802.1 organizationally
specific TLVs, network
policy TLVs, and location
identification TLVs, are
advertisable on a Layer 3
Ethernet port.
