一台cisco 4506和另一台cisco4006组成双机热备份环境！其中4506为主交换机，4006为备用状态。
1、在4006上在接口开启ip pim dense-mode后（生产环境下要用到组播），发现CPU利用率极高，达到90%还多，而且用show process cpu也看不出哪个进程占了多少cpu，最多的也不超过1%。我把相关几个接口上的组播配置删除了以后，发现4006三层的CPU使用率就降到10％左右了了。是不是4006三层模块处理能力有问题？该怎么解决呢？请说详细点！
2、还有就是4006二层模块上的CPU使用率指示灯（0％－100％那排）一个都不亮，应该有问题吧？即使利用率很低，那个0%的指示灯也应该亮吧，为什么这个却一个都不亮呢？  |

2、还有4006模块上的CPU使用率指示灯（0％－100％那排）一个都不亮，应该有问题吧？这个应该是什么问题呢？求救！
－说明很好吖
搞网络这东西，基本上很难。 要保持清醒，提高警惕。 |

最少0%的那个应该亮吧？ |

对了，这个4506为交换机，那个4006为备用的。这个和cpu使用率指示灯一个都不亮是不是有关系呢？
急死人了，没有回复的！ |

灯不亮说明你流量小，没什么不正常的
启动组播后当然影响性能，关掉后就降下去了，也正常啊 |

可是另一台4506的流量也小啊，它的0%的灯就是亮的。会不会是硬件有问题呢？难道说流量小的时候，CPU利用率为0%的灯也不亮吗？
还有，就是那个双机备份的主4506，它也开启了组播，但是为什么它的cpu利用率却不高，一直在8%－15%左右。而这个备用的4006开启了组播后，它的cpu利用率一下子就升到了90%左右，当我把组播关了后就降为5%左右。我用show process cpu和show process mem来查看，没有看见什么异常呀。命令输出如下：

顺便说一下，这个软件的版本为Version 12.0(7)W5(15b) RELEASE SOFTWARE，而另一台主的4506交换机的IOS版本为12.1。我好像听说有的IOS版本对组播的支持不是那么好，是这样的吗？
我这个问题该如何解决呢？谢谢大家！

4506和4006的开发时间相隔了5~6年，性能表现差异是很大的。
4232-L3性能本来就差，软件又老，连3560的性能都比不上，最好还是别用了。如果非要用的话，升级一下软件先。
组播尤其是dense-mode 是比较影响性能的，除非网络中30%以上的机器都要接收同一个组播流，否则不用考虑dense mode.
交换机面板上的指示灯不是指示CPU利用率的，而是指示系统（背板）利用率。4000/6000 交换引擎的背板利用率可以用show system看到，0%灯不亮也正常。

首先谢谢麦子。我知道dense-mode是比较影响性能，我试着用过ip pim sparse-mode，但是性能基本上没有任何改变。另外，我有点疑惑，那个show process cpu显示出来cpu的利用率达91%，可是我把下面的那些进程占用的cpu利用率加起来也不到7%左右呀，为什么呢？是不是有什么没有显示出来？  |

这个是经典的问题了，Cisco的解释就是由于CPU利用率的计算是“瞬间”的，所以不准。

？？？也就是说我开启组播后，显示的利用率为90%，其实这个4006的CPU利用率其实是7%左右的，是不是？但是我一关闭组播后，它的用show proc cpu显示出来的利用率只有8%左右，那岂不是说这个也是“瞬间”计算的，真实的岂不是快要低到0%？ |

我做过的4000双机和4500双机CPU利用率show proc cpu his平常都40-50,show proc cpu 呢，看见的只有7-8%,我都习惯了。 |

明白了，也就是说那个show process cpu是作不得数的。 |

麦子：刚才上了我发贴的另一个网站，看见网友的回复，我把它贴上来，你帮着看看是不是也有点道理呢� |
