Description:
Info
There are network configurations where the Link Layer Discovery Protocol (LLDP) needs to be disabled for HPE platforms configured with any of the HPE NVIDIA-based network adapters listed in the Scope section below. Link Aggregation Control Protocol (LACP) may not function correctly in certain environments that require Link Layer Discovery Protocol (LLDP) frames containing LACP information to be forwarded to the network stack. Therefore, LLDP needs to be disabled on the network adapter to avoid this condition.
Scope
Any HPE platform configured with any of the following HPE NVIDIA CX-4/CX-5/CX-6/CX-7 chipset-based network adapters: Mellanox MCX623105AS-VDAT Ethernet 200Gb 1-port QSFP56 Adapter for HPE (P10180-B21) Mellanox MCX623106AS-CDAT Ethernet 100Gb 2-port QSFP56 Adapter for HPE (P25960-B21) Mellanox MCX631102AS-ADAT Ethernet 10/25Gb 2-port SFP28 Adapter for HPE (P42044-B21) Mellanox MCX631432AS-ADAI Ethernet 10/25Gb 2-port SFP28 OCP3 Adapter for HPE (P42041-B21) HPE InfiniBand HDR/Ethernet 200Gb 2-port QSFP56 PCIe4 x16 OCP3 MCX653436A-HDAI Adapter (P31348-B21) HPE InfiniBand HDR100/Ethernet 100Gb 1-port QSFP56 PCIe3 x16 MCX653105A-ECAT Adapter (P06250-B21) HPE InfiniBand HDR100/Ethernet 100Gb 2-port QSFP56 PCIe3 x16 MCX653106A-ECAT Adapter (P06251-B21) HPE InfiniBand HDR100/Ethernet 100Gb 2-port QSFP56 PCIe4 x16 MCX653106A-ECAT Adapter (P23666-B21) HPE InfiniBand HDR100/Ethernet 100Gb 1-port QSFP56 PCIe4 x16 MCX653105A-ECAT Adapter (P23665-B21) HPE InfiniBand HDR/Ethernet 200Gb 1-port QSFP56 PCIe4 x16 MCX653105A-HDAT Adapter (P23664-B21) HPE InfiniBand HDR/Ethernet 200Gb 1-port QSFP56 PCIe4 x16 OCP3 MCX653435A-HDAI Adapter (P31323-B21) HPE InfiniBand HDR/Ethernet 200Gb 2-port QSFP56 PCIe4 x16 MCX653106A-HDAT Adapter (P31324-B21) Mellanox MCX512F-ACHT Ethernet 10/25Gb 2-port SFP28 Adapter for HPE (P13188-B21) Mellanox MCX562A-ACAI Ethernet 10/25Gb 2-port SFP28 OCP3 Adapter for HPE (P10112-B21) HPE Ethernet 100Gb 1-port QSFP28 PCIe3 x16 MCX515A-CCAT Adapter (P31246-B21) HPE Ethernet 100Gb 2-port QSFP28 MCX516A-CCHT Adapter (P21927-B21) HPE Ethernet 10Gb 2-port SFP+ MCX4121A-XCHT Adapter (P21930-B21) HPE Ethernet 10/25Gb 2-port SFP+ MCX4621A-ACAB OCP3 Adapter (P11341-B21) HPE Edgeline e920 10GbE 2-port Network Mezzanine Kit (P40899-B21) HPE InfiniBand HDR/Ethernet 200Gb 1-port QSFP56 PCIe3 x16 MCX653105A-HDAT Adapter (P06154-B21) HPE InfiniBand EDR/Ethernet 100Gb 2-port 841QSFP28 Adapter (872726-B21) HPE InfiniBand FDR/Ethernet 40/50Gb 2-port 547FLR-QSFP Adapter (879482-B21) HPE Ethernet 10/25Gb 2-port 640FLR-SFP28 Adapter (817749-B21) HPE Ethernet 10/25Gb 2-port SFP28 MCX4121A-ACUT Adapter (817753-B21) HPE Ethernet 10Gb 2-port 548SFP+ Adapter (P11338-B21) HPE InfiniBand EDR/Ethernet 100Gb 1-port 840QSFP28 Adapter (825110-B21) HPE InfiniBand EDR/Ethernet 100Gb 2-port 840QSFP28 Adapter (825111-B21) HPE Synergy 6410C 25/50Gb Ethernet Adapter (868779-B21) Note: The network adapter(s) in this document are affected by a naming standard change for HPE products to help customers quickly and easily identify the specific vendor and model while configuring HPE platforms. For more information about the name changes and for identification purposes, refer to the following Customer Notice: HPE Network Adapters - Product Renaming Framework And Plan For HPE Network Adapters
Resolution
To disable LLDP in the Operating System, perform the following steps: Check the current LLDP status of the network adapters using the following commands: # export ETH_BUS_INFO=<bus-info> where <bus-info> is given by ethtool -i <ethX> # mlxconfig -d $ETH_BUS_INFO query | grep LLDP The following example shows the output where LLDP is enabled on both ports: LLDP_NB_DCBX_P1 True(1) LLDP_NB_RX_MODE_P1 ALL(2) LLDP_NB_TX_MODE_P1 ALL(2) LLDP_NB_DCBX_P2 True(1) LLDP_NB_RX_MODE_P2 ALL(2) LLDP_NB_TX_MODE_P2 ALL(2) If LLDP is enabled, use the mlxconfig utility to disable LLDP on the ports. The following example shows how to disable LLDP on two ports: # mlxconfig -d $ETH_BUS_INFO set LLDP_NB_DCBX_P1=FALSE # mlxconfig -d $ETH_BUS_INFO set LLDP_NB_RX_MODE_P1=OFF # mlxconfig -d $ETH_BUS_INFO set LLDP_NB_TX_MODE_P1=OFF # mlxconfig -d $ETH_BUS_INFO set LLDP_NB_DCBX_P2=FALSE # mlxconfig -d $ETH_BUS_INFO set LLDP_NB_RX_MODE_P2=OFF # mlxconfig -d $ETH_BUS_INFO set LLDP_NB_TX_MODE_P2=OFF Verify that LLDP is disabled by using the mlxconfig utility as follows: # mlxconfig -d $ETH_BUS_INFO query| grep LLDP LLDP_NB_DCBX_P1 False(0) LLDP_NB_RX_MODE_P1 OFF (0) LLDP_NB_TX_MODE_P1 OFF (0) LLDP_NB_DCBX_P2 False(0) LLDP_NB_RX_MODE_P2 OFF(0) LLDP_NB_TX_MODE_P2 OFF(0) Reboot the system. Check that all settins are correct with the mlxconfig utility as follows: # mlxconfig -d $ETH_BUS_INFO query| grep LLDP LLDP_NB_DCBX_P1 False(0) LLDP_NB_RX_MODE_P1 OFF (0) LLDP_NB_TX_MODE_P1 OFF (0) LLDP_NB_DCBX_P2 False(0) LLDP_NB_RX_MODE_P2 OFF(0) LLDP_NB_TX_MODE_P2 OFF(0) RESOURCES/INFORMATION NVIDIA Firmware Tools: mlxconfig is included in NVIDIA Firmware Tools at the following URL: NVIDIA Firmware Tools (MFT) MFT documentation: For more information about the LLDP parameters and settings, refer to the Mellanox Firmware Tools (MFT) Documentation available at the NVIDIA website. For some of the HPE network adapters listed in the Scope section, the LLDP is set "Disabled" by default; therefore, make sure to use the commands described in the Resolution to verify the current LLDP status in case of possible configuration changes.
