Firmware Link Layer Discovery Protocol (FW-LLDP)

Devices based on the Intel® Ethernet 800 and 700 Series use a Link Layer Discovery Protocol (LLDP) agent that runs in the firmware. When it is running, it prevents the operating system and applications from receiving LLDP traffic from the network adapter.

• The FW-LLDP setting is per port and persists across reboots.

• The FW-LLDP Agent is required for Data Center Bridging (DCB) to function.

Adapters Based on the Intel® Ethernet 800 Series

FW-LLDP is disabled in NVM by default. To enable/disable the FW-LLDP Agent:

• Linux: Use ethtool to persistently set or show the fw-lldp-agent private flag.

• FreeBSD: Use sysctl to persistently set or show the fw_​lldp_​agent flag.

• ESX: Use the esxcli command to persistently set or get the fw-lldp-agent setting.

• Microsoft Windows: The base driver does not persistently change FW-LLDP. Use the LLDP Agent attribute in UEFI HII to persistently change the FW-LLDP setting. If you enable DCB when FW-LLDP is disabled, the base driver temporarily starts the LLDP Agent while DCB functionality is enabled.

Adapters Based on the Intel® Ethernet 700 Series

FW-LLDP is enabled in NVM by default. To enable/disable the FW-LLDP Agent:

• Linux: Use ethtool to set or show the disable-fw-lldp private flag.

• FreeBSD: Use sysctl to set or show the fw_​lldp flag.

• ESX: Use the esxcfg-module command to set or get the LLDP module parameter.

• Microsoft Windows: Use the LLDP Agent attribute in UEFI HII to change the FW-LLDP setting. Note: You must enable the UEFI HII LLDP AGENT attribute for the FW-LLDP setting to take effect. If “LLDP AGENT” is set to disabled in UEFI HII, you cannot enable FW-LLDP from the OS.

• You must enable the LLDP Agent from UEFI HII to use DCB.
