소개
이 문서는 Catalyst 9800과 다양한 종류의 내역 이벤트를 나열하는 빠른 참조 가이드입니다.9800 플랫폼의 Always-On 로깅 기능을 활용하면 특정 로그 라인이 어떻게 표시되는지 알고 있는 경우 특정 유형의 이벤트를 빠르고 쉽게 나열할 수 있습니다.
구조
이 문서는 모든 무선 관련 이진 로그(활성 디버깅의 어떤 형태도 활성화하지 않고 항상 켜져 있음)를 거치는 "show logging profile wireless" 명령의 사용에 대해 다룹니다.
"start last <time period>"는 로그의 특정 기간까지 돌아갈 수 있습니다.
파이프를 사용하여 검색을 제한하지 않을 경우 이 명령은 터미널에 많은 데이터를 출력합니다. 따라서 아래의 모든 예제는 특정 이벤트와 함께 파이프를 사용합니다.
