從vlan 7 , vlan 44 , vlan11 上看，狀態(tài)穩(wěn)定不下來。我曾經(jīng)提醒你說，只在做主響應(yīng)的路由器4506上使用preempt參數(shù)，你最初給的配置清單顯示，在3750上你也用了該參數(shù)。造成他們爭奪active身份。

    應(yīng)該不會。從規(guī)程上來看。優(yōu)先級相同則比較MAC。

1、你確信是銷售大廳的2960接入后就有問題?:
   是的我可以確定，因?yàn)槲椰F(xiàn)在的網(wǎng)絡(luò)就是將（立體庫、主廠房、輔助樓）三個地方接入層的設(shè)備分別接入45 和37的，而我一但將銷售大廳接入的就出問題。
  另外我將其他三個地方接入層設(shè)備撥掉時,只接銷售大廳，也出現(xiàn)問題。
2、把2960下接PC的線都拔掉，直接2條線分別接45和37也出現(xiàn)問題。
  我沒有做的這么徹底，（就是沒有撥線），我只做了用一臺接入設(shè)備去連45和37
3、把2960換掉也出問題。
   是的，我用另外一臺2960單臺接入也是出現(xiàn)問題，只不過這臺設(shè)備也是從銷售大廳原有的設(shè)備.
不確定的問題：
2960和45/37間是一條鏈路還是做了鏈路聚合。這些鏈路是光纖還是電接口。
是一條鏈路，中間的物理線是光纖（單模），通過光纖收發(fā)器轉(zhuǎn)成電口的，再接到2960上的
其他三幢樓也是同樣的道理 。

    您好，你怎么就確定就只有 vlan 7 44 11這三個不穩(wěn)定，其他的確都穩(wěn)定。
從3750 log 上看，所有的vlan都有從speak--->active的過程,都沒有規(guī)律的

另外一個細(xì)節(jié)就是我在另外一個局域網(wǎng)完全安照些配置方法去做，一點(diǎn)問題都沒有。

qdigrp

我現(xiàn)在，在想是或需要，將備用的3750給更換掉的，換另外一臺3750來做standby

好像不僅這3個vlan，我只追蹤了這3個，發(fā)現(xiàn)他們在短時間內(nèi)不停轉(zhuǎn)換身份，故推測可能是45和37上都使用了preempt參數(shù)導(dǎo)致的。因?yàn)檎�常配制的話，不是都使用這個參數(shù)的。
正常情況應(yīng)該是speak ---> active后，不會在短時間內(nèi)頻繁切換呀。某些vlan好像就穩(wěn)定在active狀態(tài)。

從他貼出的配置看，優(yōu)先級是不同的。但兩邊都使用preempt，我覺得不應(yīng)該，按道理來說，只能定義一個為主，另一個為輔。不能讓兩個都競爭主。就如同公司有一個正總裁，一個副總裁，當(dāng)正總裁不在的時候，副總裁可以代替總裁行使總裁職權(quán)，當(dāng)正總裁回來的時候，副總裁就要交回權(quán)利，不能握著權(quán)利不放。

你可能說的有道理，因?yàn)槲以缟弦寻褌溆玫?750做cold restart  處理，然后在網(wǎng)絡(luò)正常用的情況下得到的以下log：

那按照您的意思 我應(yīng)該如何處理，是不是在備用的3750上去掉preempt參數(shù)???

可為什么其他三幢樓的接入層，接入，就沒有任何問題.
