IPMP奇怪问题，大家帮忙看下

本帖最后由 gwl48 于 2010-07-29 23:05 编辑

4台T5120，solairs10系统，e1000g0,e1000g配置1IPMP后，第一次拔g0口，浮动IP成功飘过去，然后插入G0网线，浮动IP无法飘回G0上,

        inet 192.168.100.3 netmask ffffff00 broadcast 192.168.100.255

重启后发现检测到 e1000g1 坏，进行系统后会ping通1-2次后就不通了.多次重启一样.用g2和g3做IPMP现象一样，显示备网卡failed.单独给4个网卡配IP正常.现网络架构是T5120接两台H3交换机，交换机配VLAN，网关是交换机.先怀疑是交换机问题，但单独拿cisco2950或dlink的小交换机接G0和G1口，笔记本当网关，问题依旧。大家帮我看看！硬件应该没问题.

查看一下 default router 还在么？

netstat -rn
