查看机器网络端口

[trafodion@n12 ~]$ ifconfigeth1      Link encap:Ethernet  HWaddr 5C:B9:01:9A:48:5D          inet addr:10.10.11.12  Bcast:10.10.11.255  Mask:255.255.255.0          inet6 addr: fe80::5eb9:1ff:fe9a:485d/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:18033924355 errors:0 dropped:857504 overruns:0 frame:0          TX packets:52425526574 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000          RX bytes:66937144646066 (60.8 TiB)  TX bytes:60037314294532 (54.6 TiB)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:1192347276 errors:0 dropped:0 overruns:0 frame:0          TX packets:1192347276 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:0          RX bytes:9188133537474 (8.3 TiB)  TX bytes:9188133537474 (8.3 TiB)

查看端口带宽(root或sudo权限)，通过下面输出可以看到speed那一行，表示万兆网。

[trafodion@n12 ~]$ sudo ethtool eth1Settings for eth1:        Supported ports: [ FIBRE ]        Supported link modes:   10000baseT/Full        Supported pause frame use: No        Supports auto-negotiation: No        Advertised link modes:  10000baseT/Full        Advertised pause frame use: No        Advertised auto-negotiation: No        Speed: 10000Mb/s        Duplex: Full        Port: FIBRE        PHYAD: 0        Transceiver: external        Auto-negotiation: off        Supports Wake-on: d        Wake-on: d        Current message level: 0x00000007 (7)                               drv probe link        Link detected: yes
