求助：新添加的网卡不工作

goldenbear

我的150机器上原来有一块集成网卡，工作正常。后台添加了一块IBM原装网卡，用命令lsdev和ifconfig查看都很正常。但是从另一台计算机ping它时，其中原来的集成网卡能够断断续续收到一些信息，新添加的网卡根本就没有响应。两个网卡互相ping时，都能收到信息。把后面的网卡删除后，以前的集成网卡又工作正常。

请大家帮我分析一下，可能是什么原因？是不是这块网卡坏了？怎样证明坏了？

RS9000

你新网卡IP怎么配的？？

看看两个网卡的配置

you must config the two adapters in the same net and you did not use the no command to do the ipforwarding. haha.

我的网卡的设置信息：
# ifconfig -a
en0: flags=4e080863,80<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,PSEG,CHAIN>;

看样子都很正常，但是ping 这台机器时，其中一个网卡能断断续续收到一些信息，另一个网卡根本没有响应。如果只保留原来的集成网卡，则正常。

dear goldenbear:

I even do not see your 网卡的设置信息, I have said that"you must config the two adapters in the same net and you did not use the no command to do the ipforwarding. haha."

but you do not read my answer.

that's why you can not configure your network adapter to work well.


OK  ??????

RS9000

2个IP不要配在同一网段，试试

koala_mel

inet 192.168.1.100 netmask 0xffffff00 broadcast
inet 192.168.1.200 netmask 0xffffff00 broadcast

if you change 192.168.1.200 in to 192.168.2.200 you will success.

or you change your netmask from 0xffffff00 into some what.. is also ok

好的，今晚回去试试。先谢谢各位高手了！
