CiscoAP1562（已经刷了ME和CAPWAP）在reset重新通过配置向导配置初始化完成后，始终不能ping（电脑与AP直连，AP用POE模块供电）通管理地址，以及AP1562的status指示灯一直闪烁红色，console界面也一直显示： [05/20/2019 06:10:14.8200] wired0 emac 1: link up [05/20/2019 06:10:14.8800] wired0: link up [05/20/2019 06:10:14.9200] wired0: started [05/20/2019 06:10:30.0900] wired0: stopped [05/20/2019 06:10:32.1900] wired0 emac 1: link up [05/20/2019 06:10:32.2400] wired0: link up [05/20/2019 06:10:32.2900] wired0: started [05/20/2019 06:10:47.4700] wired0: stopped [05/20/2019 06:10:49.5400] wired0 emac 1: link up [05/20/2019 06:10:49.6000] wired0: link up [05/20/2019 06:10:49.6400] wired0: started [05/20/2019 06:11:04.8400] wired0: stopped [05/20/2019 06:11:06.9100] wired0 emac 1: link up [05/20/2019 06:11:06.9600] wired0: link up [05/20/2019 06:11:07.0100] wired0: started [05/20/2019 06:11:22.1800] wired0: stopped [05/20/2019 06:11:24.2800] wired0 emac 1: link up [05/20/2019 06:11:24.3300] wired0: link up [05/20/2019 06:11:24.3800] wired0: started 大意就是网线端口不断开启关闭，查了CiscoAP指示灯信息（谷歌翻译）： 表示网口链路有问题。PS：网口有问题的话，AP不可能启动的起来（只有一个网口，且POE供电）。 造成以上问题的原因就是CAPWAP下没有配置IP（配置向导初始化时我未启用DHCP），手动配置IP及可解决。 从ME模式切换到CAPWAP模式： (Cisco Controller) > apciscoshell AP7070.8BD0.0342> enable AP7070.8BD0.0342# capwap ap ip 10.10.10.10 255.255.255.0 10.10.10.1 #任意配个私有IP AP7070.8BD0.0342#logout (Cisco Controller) >save config
