网卡的驱动及型号： 01:00.0 Ethernet controller: Chelsio Communications Inc T420-CR Unified Wire Ethernet Controller 01:00.1 Ethernet controller: Chelsio Communications Inc T420-CR Unified Wire Ethernet Controller 01:00.2 Ethernet controller: Chelsio Communications Inc T420-CR Unified Wire Ethernet Controller 01:00.3 Ethernet controller: Chelsio Communications Inc T420-CR Unified Wire Ethernet Controller 01:00.4 Ethernet controller: Chelsio Communications Inc T420-CR Unified Wire Ethernet Controller 01:00.5 SCSI storage controller: Chelsio Communications Inc T420-CR Unified Wire Storage Controller 01:00.6 Fibre Channel: Chelsio Communications Inc T420-CR Unified Wire Storage Controller 配置好了以后，lsmod可以看到驱动模块已加载： [root@167 ~]# lsmod |grep cxgb4 cxgb4 98749 0 配置了IP后，只有eth0是通的，eth1不通，但用ethtool工具显示是连接的： [root@167 ~]# ethtool eth1 Settings for eth1: Supported ports: [ FIBRE ] Supported link modes: Supports auto-negotiation: No Advertised link modes: Not reported Advertised pause frame use: No Advertised auto-negotiation: No Speed: 10000Mb/s Duplex: Full Port: Direct Attach Copper PHYAD: 0 Transceiver: internal Auto-negotiation: off Supports Wake-on: bg Wake-on: d Current message level: 0x000000ff (255) Link detected: yes 想修改auto-negotiation失败： [root@167 ~]# ethtool -A eth1 autoneg on Cannot set device pause parameters: Invalid argument 问题有： 1、为什么“Supported link modes:”后面没有显示任何信息？网络不通是不是跟这个有关系？但eth0也没有显示，确可以ping通。 2、“Supports auto-negotiation: No”，是否带TOE功能的网卡，都不支持auto-negotiation ？ (责任编辑：IT) |
