求助:AC+AP环境,昨天开始AP批量掉线,掉线20多分钟后又批量上线,检查AC又未死机,核心-AP AC-AP 网络延迟又正常
(0)
最佳答案
在AC上查看下AP的掉线原因:
display wlan ap statistics tunnel-down-record
(0)
看下核心或者POE交换机是否有异常日志,POE交换机是否断电。
(0)
是终端AP批量掉线,掉线时汇聚和AC都无法连接上,感觉与POE供电关系不大。

您好,以下参考
1、检查POE交换机的供电是否正常
2、检查POE交换机链路是否正常
3、检查POE交换机是否重启
4、检查AC授权是否足够
5、检查AC和交换机是否有日志反馈
6、升级下AC的软件版本

谢谢,已经解决。
谢谢,已经解决。
您好,请知:
无线网络不稳定,以下是优化要点,请参考:
1、调整功率和信道。
2、有线网络和无线网络使用不同的VLAN来实现广播域上的隔离。
3、关闭低速率的协议。
4、检查上行链路是否正常。
5、升级无线设备的软件版本到最新。
6、做好无线网络接入的安全设置,避免非法终端接入。

批量掉线,一般都是POE交换机断电
(0)
但是看了POE交换机的供电情况,只用了不到1/3的功率
但是看了POE交换机的供电情况,只用了不到1/3的功率
怀疑POE交换机有问题去看看接口是否有up down

经观察,与版本关系不大,所有交换机开启stp后该故障仍然存在
