AP 不能成功向 WLC 注册，但能拼通 WLC 的地址，在 AP 上报错如下： *Mar 1 01:56:57.467: %CAPWAP-3-ERRORLOG: Invalid event 38 & state 2 combination. *Mar 1 01:56:57.535: %DHCP-6-ADDRESS_ASSIGN: Interface BVI1 assigned DHCP address 192.168.1.7, mask 255.255.0.0, hostname AP6c41.6aca.5a72 AP6c41.6aca.5a72#ping 192.168.224.1 Type escape sequence to abort.
