建议先查看一下完整的show msglog & show traplog。看看里面有没有AP掉线时发生的日志信息。根据你提供的信息,包含了如下信息(而且这个可能是AP端口又join时发生的信息?):
*spamApTask6: Mar 26 08:00:26.012: %LWAPP-3-VENDOR_PLD_VALIDATE_ERR: spam_lrad.c:11970 Validation of SPAM_VENDOR_SPECIFIC_PAYLOAD(185) with length=9 failed - AP 70:70:8b:d7:be:d0
另外最好确认一下:
-是否是之前都没有这个问题,但是最近出现了,最近是不是网络中有什么变动?
-发生该故障的时间是否有规律性,例如每天都会发生,还是几天才发生一次?
-是否只有固定的AP发生故障,而其他的AP正常?
-是否发生故障的AP只是AP2702,如果有其他型号的AP,其他AP是否正常?
楼上给出的bug确实存在,但是有提到出现这个信息应该没什么网络影响,该问题目前只公布了8.0.110.0受影响,且还未公布fixed版本。
msglog flooded with: Validation of SPAM_VENDOR_SPECIFIC_PAYLOAD(185)
CSCus81385
Description
Symptom:
The following message is flooding the message logs.
spamApTask2: Jan 17 11:29:06.466: #LWAPP-3-VENDOR_PLD_VALIDATE_ERR: spam_lrad.c:10992 Validation of SPAM_VENDOR_SPECIFIC_PAYLOAD(185) with length=9 failed - AP b4:e9:b0:16:51:e0
There is no known network impact as a result of this message.
Conditions:
Seen after upgrading to software version 8.0.110.0.
Workaround:
None
Further Problem Description:
如果有必要,建议在WLC和AP上采集故障时候的debug信息:
WLC:
debug capwap errors enable
debug capwap event enable
debug dtls all enable
AP:
debug capwap client event
debug capwap client error
debug dtls client error
debug dtls client event
或者看看AP上次断开是由于什么原因,例如
show ap join stats detail <
ap mac add>
希望可以帮到你
