ping 一个地址出现错误，且表示一点疑惑

liujinwei619

问题简述：两台t5240做的双机，在主机上ping  202.98.224.8这个IP地址，会出现下面的现象，但在备机上ping无问题
疑惑：下面我ping 了150个包，最后统计结果是一个包都没有掉，但ping的过程当中明明有掉包现象（ICMP Port Unreachable from gateway host2 (202.98.224.
for udp from trans1.ls.xz.cn (10.1.1.11) to host2 (202.98.224. port 61741
）  这是什么原因了？

是不是跟那个机器本身软件或协议有关。那个port每次都在变。

    首先谢谢你的回答、、、~~我也在想是否与这有关、、、~~ 我考虑过是否是补丁的问题、、、但是另一台备机上PING那个IP地址却没有这种现象，因为两台机子都是一起装的、、、哎。、、在慢慢研究下、、、呵呵、、

不会是你主机业务太忙，网卡太忙了吧
