Wifi 연결 이슈 관련하여 WLC 측 debug client 뿐만 아니라 AP client-tace 로그도 같이 수집하면 원인 분석에 많은 도움을 줄수 있습니다.
・AP client-trace 수집 방법：
config ap client-trace address add xx:xx:xx:xx:xx:xx
config ap client-trace filter all enable
config ap client-trace output console-log enable ＞＞＞ SSH 콘솔로 출력
show ap client-trace status ＞＞＞ 설정 및 시작 상태 확인
config ap client-trace start ＞＞＞ 수집 시작
・AP client-trace 수집 중지 방법 ：
config ap client-trace stop
config ap client-trace filter all disable
config ap client-trace address delete xx:xx:xx:xx:xx:xx
