SNMP 모니터링

Cisco AsyncOS 운영 체제는 SNMP(Simple Network Management Protocol)를 통해 시스템 상태 모니
터링을 지원합니다. 여기에는 Cisco의 엔터프라이즈 MIB, ASYNCOS-MAIL-MIB가 있습니다. 
ASYNCOS-MAIL-MIB를 활용하면 관리자가 시스템 상태를 보다 효율적으로 모니터링할 수 있습
니다. 또한 이 릴리스는 RFC 1213 및 1907의 정의에 따라 MIB II의 읽기 전용 하위 집합을 구현합
니다. (SNMP에 대한 자세한 내용은 RFC 1065, 1066 및 1067을 참조하십시오.) 참고: 

SNMP는 기본적으로 비활성화되어 있습니다. 

SNMP SET 연산(구성)은 구현되지 않았습니다.

AsyncOS는 SNMPv1, v2 및 v3를 지원합니다.

SNMPv3를 활성화할 때 메시지 인증 및 암호화는 필수사항입니다. 인증과 암호화를 위한 비밀
번호는 서로 달라야 합니다. 암호화 알고리즘은 AES(권장) 또는 DES를 사용할 수 있습니다. 인
증 알고리즘은 SHA-1(권장) 또는 MD5를 사용할 수 있습니다. 

snmpconfig

 명령은 다음에 명령

을 실행할 때 비밀번호를 "기억"합니다. 

SNMPv3 사용자 이름: v3get. 

SNMPv1 또는 SNMPv2만 사용하는 경우, 커뮤니티 문자열을 설정해야 합니다. 커뮤니티 문자
열은 기본값이 

public

으로 설정되어 있지 않습니다.

SNMPv1 및 SNMPv2의 경우, SNMP GET 요청을 수락한 네트워크를 지정해야 합니다.
