Solaris 8，网络连接失败.

Sun Fire v100, Solaris 8\r\n配置了双网卡，原来使用的是dmfe0。dmfe0出了故障，用dmfe1替换使用，配置如下。\r\n\r\n# ifconfig -a\r\nlo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1\r\n        inet 127.0.0.1 netmask ff000000\r\ndmfe1: flags=1000863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST,IPv4> mtu 1500 in\r\ndex 2\r\n        inet 172.20.40.21 netmask ffffff00 broadcast 172.20.255.255\r\n        ether 0:3:ba:35:c7:36\r\ndmfe0: flags=1000862<BROADCAST,NOTRAILERS,RUNNING,MULTICAST,IPv4> mtu 1500 index\r\n 3\r\n        inet 0.0.0.0 netmask 0 broadcast 255.255.255.255\r\n        ether 0:3:ba:35:c7:36\r\n\r\n# ping 172.20.40.21\r\n成功。\r\n# ping 172.20.40.254\r\n失败。\r\n\r\n# ifconfig dmfe0 down\r\n# init 6\r\n\r\n# ifconfig -a\r\nlo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1\r\n        inet 127.0.0.1 netmask ff000000\r\ndmfe1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2\r\n        inet 172.20.40.21 netmask ffffff00 broadcast 172.20.40.255\r\n        ether 0:3:ba:35:c7:36\r\n\r\n\r\n\r\n# ping 172.20.40.21\r\n成功。\r\n# ping 172.20.40.254\r\n失败。\r\n\r\n重装系统也是一样。\r\n是不是\r\n\r\n请赐教。

你这不是双网卡，是一块网卡有多个端口。你可以通过查看# grep network /etc/path_to_inst 了解。我是由你的MAC看的。\r\n\r\n/etc/hosts /etc/hostname.dmfe1 文件配置（做）了没有？\r\n\r\n# ifconfig dmfe0 down ？ 停用设备用unplumb
