1、使用ifconfig查看当前网卡
/ # ifconfig bridge0 Link encap:Ethernet HWaddr 4A:B3:0C:01:C1:8B inet addr:172.31.234.26 Bcast:172.31.234.27 Mask:255.255.255.252 inet6 addr: fe80::48b3:cff:fefe:be88/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2752 errors:0 dropped:0 overruns:0 frame:0 TX packets:745 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:192468 (187.9 KiB) TX bytes:47651 (46.5 KiB) eth0 Link encap:Ethernet HWaddr 00:80:48:BA:D1:30 inet addr:169.254.4.1 Bcast:169.254.4.255 Mask:255.255.255.0 inet6 addr: fe80::280:48ff:feba:d130/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4867 errors:5 dropped:9 overruns:0 frame:2 TX packets:715 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:490146 (478.6 KiB) TX bytes:58813 (57.4 KiB) Interrupt:108 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:7 errors:0 dropped:0 overruns:0 frame:0 TX packets:7 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:400 (400.0 B) TX bytes:400 (400.0 B)
2、使用ethtool eth0查看网卡信息
/ # ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: Yes Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Link partner advertised pause frame use: No Link partner advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: MII PHYAD: 0 Transceiver: external Auto-negotiation: on Supports Wake-on: pg Wake-on: p Current message level: 0x00007fff (32767) drv probe link timer ifdown ifup rx_err tx_err tx_queued intr tx_done rx_status pktdata hw wol Link detected: yes
3、修改网卡配置
ethtool -s eth0 speed 10 duplex full autoneg off
将网卡eth0对应的物理端口设置为速率10Mbps，全双工工作模式，关闭自动协商。
4、查看网卡信息，配置成功
/ # ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Advertised link modes: 10baseT/Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: No Speed: 10Mb/s Duplex: Full Port: MII PHYAD: 0 Transceiver: external Auto-negotiation: off Supports Wake-on: pg Wake-on: p Current message level: 0x00007fff (32767) drv probe link timer ifdown ifup rx_err tx_err tx_queued intr tx_done rx_status pktdata hw wol Link detected: yes
