SW_MATM-4-MACFLAP_NOTIF 这种故障如何解决？

qdigrp

好像事情向好的方向发展了，目前我已将两幢接入层的设备接入，通过5天的观察，一点都没有问题，也就是说没有出现类似于13w4d: %C4K_EBM-4-HOSTFLAPPING: Host 00:90:27:90:1C:25 in vlan 15 is flapping between port Gi3/1 and port Po1这样的故障！

那么接下去就只有另外两个接入设备了。假如只有一个设备有问题，比如说是“销售大厅”，那我应该如何做，因为前期我已将哪里的物理线路，和配置做了两天的排查，好像都没有问题。

你先别急。找到那组设备处的问题再进行排查。

很遗憾！当我将第四个接入层设备（销售大厅）接入的时候，故障十分钟左右就出现了。
这里可能有两种情况，第一，可能是销售大厅里的网络有问题！（局部的）
                    第二，可能是只有当所有的接入设备都接入，故障才会出现！（整体的）

现在的状态已回到了二周前的状态，无奈！！！

现在，很明显了，就是销售大厅的网络有问题，因为我将其他三个地方的接入层断掉的情况下，只接销售大厅的接入设备，故障也会出现，平均十分钟一次。

    只把销售大厅的接4506的那一台接上，下面的先不接，看问题如何，这样缩小范围。看是这一台有问题，还是他下面的有问题。
