为什么网络接口老是down掉？

我的880网卡设置了两个IP，10.32.7.11和10.32.7.32
# ifconfig -a   
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
eri0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 10.32.7.11 netmask ffffff00 broadcast 10.32.7.255
        ether 0:3:ba:2f:15:d2
ge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
        inet 10.32.7.32 netmask ffffff00 broadcast 10.32.7.255
        ether 0:3:ba:2f:15:d3
ping 10.32.7.11很正常，ping 10.32.7.32时时通时断。日志如下：

谁能帮着解决一下？

没道理呀
楼主检查下硬件

解决了，是交换接接SUN的光纤模块有问题了，换了一个就好了。

是不是不可以在SUN运行的时候拔出网线？上次我这样操作了之后，sun就自动重启了。
