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.

Version History

Introduced in Cumulus Linux 5.1.0

Example

cumulus@switch:~$ nv set interface swp1 lldp dcbx-pfc-tlv on

nv set interface <interface-id> lldp state

Enables and disables LLDP on an interface.

When you disable LLDP on an interface, LLDP and CDP packet transmission stops on the interface.

Command Syntax

Syntax	Description
`<interface-id>`	The interface you want to configure.

Version History

Introduced in Cumulus Linux 5.11.0

Example

cumulus@switch:~$ nv set interface swp1 lldp state disabled

nv set service lldp application-tlv app <application> priority <priority-id>

Configures the specified application TLV priority.

Command Syntax

Syntax	Description
`<application-id>`	The application name.
`<priority-id>`	The priority ID.

Version History

Introduced in Cumulus Linux 5.9.0

Example

cumulus@switch:~$ nv set service lldp application-tlv app iSCSI priority 3

nv set service lldp application-tlv tcp-port <port-id> priority <priority-id>

Configures the application priority for TCP traffic for the specified port.

Command Syntax

Syntax	Description
`<port-id>`	The port number.
`<priority-id>`	The priority ID.

Version History

Introduced in Cumulus Linux 5.9.0

Example

cumulus@switch:~$ nv set service lldp application-tlv tcp-port 4217 priority 6

nv set service lldp application-tlv udp-port <port-id> priority <priority-id>

Configures the application priority for UDP traffic for the specified port.

Command Syntax

Syntax	Description
`<portid>`	The port number.
`<priority-id>`	The priority ID.

Version History

Introduced in Cumulus Linux 5.9.0

Example

cumulus@switch:~$ nv set service lldp application-tlv udp-port 4317 priority 4

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-cdpv1 configures the lldpd service to send only CDPv1 frames.
force-send-cdpv2 configures the lldpd service to send only CDPv2 frames.
force-send-lldp configures the lldpd service 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 state

Enables and disables LLDP globally. Cumulus Linux enables the LLDP service by default.

When you disable LLDP globally, the lldp service, and all LLDP and CDP packet transmission stops.

Version History

Introduced in Cumulus Linux 5.11.0

Example

cumulus@switch:~$ nv set service lldp state disabled

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
