在RedHat或者CentOS系统下切换 Infiniband卡的工作模式 Infiniband卡支持两种工作模式：IB模式和 Ethernet模式 首先，启动mst 工具，通过 mst工具查看自己的MST devices：/dev/mst/mt4119_pciconf0 （没有mst工具，需要下载安装） [root@localhost ~]# systemctl start mst [root@localhost ~]# mst status MST modules: ------------ MST PCI module is not loaded MST PCI configuration module loaded MST devices: ------------ /dev/mst/mt4119_pciconf0 - PCI configuration cycles access. domain:bus:dev.fn=0000:c4:00.0 addr.reg=88 data.reg=92 cr_bar.gw_offset=-1 Chip revision is: 00 [root@localhost ~]#查看网卡的配置信息，在下列输出中，可以看出此时网卡的工作模式是IB模式 也可以通过ifconfig去查看 [root@localhost ~]# mlxconfig -d /dev/mst/mt4119_pciconf0 query Device #1: ---------- Device type: ConnectX5 Name: MCX555A-ECA_Ax Description: ConnectX-5 VPI adapter card; EDR IB (100Gb/s) and 100GbE; single-port QSFP28; PCIe3.0 x16; tall bracket; ROHS R6 Device: /dev/mst/mt4119_pciconf0 Configurations: Next Boot MEMIC_BAR_SIZE 0 MEMIC_SIZE_LIMIT _256KB(1) HOST_CHAINING_MODE DISABLED(0) HOST_CHAINING_DESCRIPTORS Array[0..7] HOST_CHAINING_TOTAL_BUFFER_SIZE Array[0..7] FLEX_PARSER_PROFILE_ENABLE 0 FLEX_IPV4_OVER_VXLAN_PORT 0 ROCE_NEXT_PROTOCOL 254 ESWITCH_HAIRPIN_DESCRIPTORS Array[0..7] ESWITCH_HAIRPIN_TOT_BUFFER_SIZE Array[0..7] PF_BAR2_SIZE 0 NON_PREFETCHABLE_PF_BAR False(0) VF_VPD_ENABLE False(0) STRICT_VF_MSIX_NUM False(0) VF_NODNIC_ENABLE False(0) NUM_OF_VFS 0 PF_BAR2_ENABLE False(0) SRIOV_EN False(0) PF_LOG_BAR_SIZE 5 VF_LOG_BAR_SIZE 1 NUM_PF_MSIX 63 NUM_VF_MSIX 19 INT_LOG_MAX_PAYLOAD_SIZE AUTOMATIC(0) PARTIAL_RESET_EN False(0) SW_RECOVERY_ON_ERRORS False(0) RESET_WITH_HOST_ON_ERRORS False(0) ADVANCED_POWER_SETTINGS False(0) CQE_COMPRESSION BALANCED(0) IP_OVER_VXLAN_EN False(0) MKEY_BY_NAME False(0) ESWITCH_IPV4_TTL_MODIFY_ENABLE False(0) PRIO_TAG_REQUIRED_EN False(0) UCTX_EN True(1) PCI_ATOMIC_MODE PCI_ATOMIC_DISABLED_EXT_ATOMIC_ENABLED(0) TUNNEL_ECN_COPY_DISABLE False(0) LRO_LOG_TIMEOUT0 6 LRO_LOG_TIMEOUT1 7 LRO_LOG_TIMEOUT2 8 LRO_LOG_TIMEOUT3 13 LOG_DCR_HASH_TABLE_SIZE 11 DCR_LIFO_SIZE 16384 LINK_TYPE_P1 IB(1) #当前工作模式 IB ROCE_CC_PRIO_MASK_P1 255 ROCE_CC_ALGORITHM_P1 ECN(0) CLAMP_TGT_RATE_AFTER_TIME_INC_P1 True(1) CLAMP_TGT_RATE_P1 False(0) RPG_TIME_RESET_P1 300 RPG_BYTE_RESET_P1 32767 RPG_THRESHOLD_P1 1 RPG_MAX_RATE_P1 0 RPG_AI_RATE_P1 5 RPG_HAI_RATE_P1 50 RPG_GD_P1 11 RPG_MIN_DEC_FAC_P1 50 RPG_MIN_RATE_P1 1 RATE_TO_SET_ON_FIRST_CNP_P1 0 DCE_TCP_G_P1 1019 DCE_TCP_RTT_P1 1 RATE_REDUCE_MONITOR_PERIOD_P1 4 INITIAL_ALPHA_VALUE_P1 1023 MIN_TIME_BETWEEN_CNPS_P1 2 CNP_802P_PRIO_P1 6 CNP_DSCP_P1 48 LLDP_NB_DCBX_P1 False(0) LLDP_NB_RX_MODE_P1 OFF(0) LLDP_NB_TX_MODE_P1 OFF(0) DCBX_IEEE_P1 True(1) DCBX_CEE_P1 True(1) DCBX_WILLING_P1 True(1) KEEP_ETH_LINK_UP_P1 True(1) KEEP_IB_LINK_UP_P1 False(0) KEEP_LINK_UP_ON_BOOT_P1 False(0) KEEP_LINK_UP_ON_STANDBY_P1 False(0) NUM_OF_VL_P1 _4_VLs(3) NUM_OF_TC_P1 _8_TCs(0) NUM_OF_PFC_P1 8 DUP_MAC_ACTION_P1 LAST_CFG(0) SRIOV_IB_ROUTING_MODE_P1 LID(1) IB_ROUTING_MODE_P1 LID(1) PCI_WR_ORDERING per_mkey(0) MULTI_PORT_VHCA_EN False(0) PORT_OWNER True(1) ALLOW_RD_COUNTERS True(1) RENEG_ON_CHANGE True(1) TRACER_ENABLE True(1) IP_VER IPv4(0) BOOT_UNDI_NETWORK_WAIT 0 UEFI_HII_EN True(1) BOOT_DBG_LOG False(0) UEFI_LOGS DISABLED(0) BOOT_VLAN 1 LEGACY_BOOT_PROTOCOL PXE(1) BOOT_RETRY_CNT NONE(0) BOOT_INTERRUPT_DIS False(0) BOOT_LACP_DIS True(1) BOOT_VLAN_EN False(0) BOOT_PKEY 0 ATS_ENABLED False(0) DYNAMIC_VF_MSIX_TABLE False(0) EXP_ROM_UEFI_x86_ENABLE True(1) EXP_ROM_PXE_ENABLE True(1) IBM_TUNNELED_ATOMIC_EN False(0) IBM_AS_NOTIFY_EN False(0) ADVANCED_PCI_SETTINGS False(0) SAFE_MODE_THRESHOLD 10 SAFE_MODE_ENABLE True(1) [root@localhost ~]#修改网卡的工作模式： Ethernet模式： mlxconfig -d /dev/mst/mt4119_pciconf0 set LINK_TYPE_P1=2 IB模式： mlxconfig -d /dev/mst/mt4119_pciconf0 set LINK_TYPE_P1=1 [root@localhost ~]# mlxconfig -d /dev/mst/mt4119_pciconf0 set LINK_TYPE_P1=2 Device #1: ---------- Device type: ConnectX5 Name: MCX555A-ECA_Ax Description: ConnectX-5 VPI adapter card; EDR IB (100Gb/s) and 100GbE; single-port QSFP28; PCIe3.0 x16; tall bracket; ROHS R6 Device: /dev/mst/mt4119_pciconf0 Configurations: Next Boot New LINK_TYPE_P1 IB(1) ETH(2) Apply new Configuration?

[root@localhost ~]#如上，mlxconfig -d /dev/mst/mt4119_pciconf0 set LINK_TYPE_P1=2，网卡已修改为Ethernet模式，修改后需要重启机器后才生效，因为修改的是下一次（Next boot）的网卡启动的工作模式。 |
