从vlan 7 , vlan 44 , vlan11 上看，状态稳定不下来。我曾经提醒你说，只在做主响应的路由器4506上使用preempt参数，你最初给的配置清单显示，在3750上你也用了该参数。造成他们争夺active身份。

    应该不会。从规程上来看。优先级相同则比较MAC。

1、你确信是销售大厅的2960接入后就有问题?:
   是的我可以确定，因为我现在的网络就是将（立体库、主厂房、辅助楼）三个地方接入层的设备分别接入45 和37的，而我一但将销售大厅接入的就出问题。
  另外我将其他三个地方接入层设备拨掉时,只接销售大厅，也出现问题。
2、把2960下接PC的线都拔掉，直接2条线分别接45和37也出现问题。
  我没有做的这么彻底，（就是没有拨线），我只做了用一台接入设备去连45和37
3、把2960换掉也出问题。
   是的，我用另外一台2960单台接入也是出现问题，只不过这台设备也是从销售大厅原有的设备.
不确定的问题：
2960和45/37间是一条链路还是做了链路聚合。这些链路是光纤还是电接口。
是一条链路，中间的物理线是光纤（单模），通过光纤收发器转成电口的，再接到2960上的
其他三幢楼也是同样的道理 。

    您好，你怎么就确定就只有 vlan 7 44 11这三个不稳定，其他的确都稳定。
从3750 log 上看，所有的vlan都有从speak--->active的过程,都没有规律的

另外一个细节就是我在另外一个局域网完全安照些配置方法去做，一点问题都没有。

我现在，在想是或需要，将备用的3750给更换掉的，换另外一台3750来做standby

好像不仅这3个vlan，我只追踪了这3个，发现他们在短时间内不停转换身份，故推测可能是45和37上都使用了preempt参数导致的。因为正常配制的话，不是都使用这个参数的。
正常情况应该是speak ---> active后，不会在短时间内频繁切换呀。某些vlan好像就稳定在active状态。

从他贴出的配置看，优先级是不同的。但两边都使用preempt，我觉得不应该，按道理来说，只能定义一个为主，另一个为辅。不能让两个都竞争主。就如同公司有一个正总裁，一个副总裁，当正总裁不在的时候，副总裁可以代替总裁行使总裁职权，当正总裁回来的时候，副总裁就要交回权利，不能握着权利不放。

你可能说的有道理，因为我早上已把备用的3750做cold restart  处理，然后在网络正常用的情况下得到的以下log：

那按照您的意思 我应该如何处理，是不是在备用的3750上去掉preempt参数???

qdigrp

可为什么其他三幢楼的接入层，接入，就没有任何问题.
