交换机总是重新启动

显示全部楼层 · 2005-10-30 17:05:33

两台CISCO 4006 做双机热备，最近出现问题其中备机老是重新启动。也不知道是不是硬件坏了还是配置问题，有谁知道什么原因，或怎么查可以知道原因？

show ver看看重起的原因，要是故障重起，应该存在crashinfo

没有提示什么错误，会不会是由于机房环境比较热造成

1.查看CPU负载,看是否有不明进程
2.查看各端口流量是否正常.
3.以上二点均正常,请升级IOS版本

自动启动，一般是核心承受不了的一种保护方式吧？比如网络内有病毒。流量过高又受到强arp扫描。不合适的debug，或则访问控制列表加log，这些都是很容易造成的。另外两个4000，如果standby设置错误，也可能造成环路。然后就是广播风暴，很快就可以崩溃自动从新启动了，嘿嘿
