LLDP
The nv unset commands remove the configuration you set with the equivalent nv set commands. This guide only describes an nv unset command if it differs from the nv set command.
nv set interface <interface-id> lldp
Provides commands to configure LLDP on an interface.
nv set interface <interface-id> lldp dcbx-ets-config-tlv
Configures ETS TLV transmission on the interface. The default setting is off.
Command Syntax

Version History
Introduced in Cumulus Linux 5.1.0
Example
cumulus@switch:~$ nv set interface swp1 lldp dcbx-pfc-tlv on
nv set service lldp
Provides commands to configure LLDP globally on the switch.
nv set service lldp dot1-tlv
Turns dot1 TLV advertisements on or off. The default setting is off.
Version History
Introduced in Cumulus Linux 5.1.0
Example
cumulus@switch:~$ nv set service lldp dot1-tlv on
nv set service lldp lldp-med-inventory-tlv>
Configures the lldpd service to send LLDP-MED Inventory TLV advertisements. By default, Cumulus Linux transmits LLDP-MED Inventory TLV advertisements on enabled ports.
LLDP-MED is an extension to LLDP that operates between endpoint devices, such as IP phones and switches. Inventory management TLV enables an endpoint to transmit detailed inventory information about itself to the switch, such as the hardware revision, firmware version, software version, serial number, manufacturer name, and model name.
You can disable LLDP-MED inventory TLV transmission if you want LLDP to receive LLDP-MED inventory TLVs (and publish them using SNMP, if enabled) but not send them.
Version History
Introduced in Cumulus Linux 5.7.0
Example
cumulus@switch:~$ nv set service lldp lldp-med-inventory-tlv off
nv set service lldp mode <mode>
Configures the lldpd service to send only CDP frames or only LLDP frames. By default, the lldpd service sends LLDP frames unless it detects a CDP peer, then it sends CDP frames. You can set the following options:
force-send-cdpv1configures thelldpdservice to send only CDPv1 frames.force-send-cdpv2configures thelldpdservice to send only CDPv2 frames.force-send-lldpconfigures thelldpdservice to send only LLDP frames.
Version History
Introduced in Cumulus Linux 5.4.0
Example
cumulus@switch:~$ nv set service lldp mode force-send-cdpv1
nv set service lldp tx-hold-multiplier
Configures the amount of time to hold LLDP information before discarding it. The hold time interval is a multiple of the tx-interval.
Version History
Introduced in Cumulus Linux 5.0.0
Example
cumulus@switch:~$ nv set service lldp tx-hold-multiplier 3
nv set service lldp tx-interval
Configures the frequency of LLDP updates. You can specify a value between 10 and 300.
Version History
Introduced in Cumulus Linux 5.0.0
Example
cumulus@switch:~$ nv set service lldp tx-interval 100
