linux/centos如何查看网卡是100M还是1000M?检查100兆还是千兆(1GBPS)带宽接入,请看下面命令

要测试是否是1000M端口,最保险的说用wget测试一个对方的带宽足够大的下载地址: wget http://cachefly.cachefly.net/100mb.test --2011-03-14 22:19:12-- http://cachefly.cachefly.net/100mb.test Resolving cachefly.cachefly.net... 205.234.175.175 Connecting to cachefly.cachefly.net|205.234.175.175|:80... connected.
