[root@rhel6 ~]# ip link set name jiahu eth1 [root@rhel6 ~]# ifconfig jiahu jiahu Link encap:Ethernet HWaddr 00:1B:21:27:4E:CE BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) [root@rhel6 ~]# ifup jiahu Determining IP information for jiahu... done.
