예: VLAN에 스케줄링 및 셰이핑 적용
이 예는 개별 논리 인터페이스에 스케줄러를 적용하는 방법을 보여줍니다.
요구 사항
이 예는 다음과 같은 하드웨어 및 소프트웨어 구성 요소를 사용합니다.
Junos OS 지능형 큐잉(IQ)을 지원하는 라우터 라인 카드에서 실행되는 릴리스 7.4 이상
Junos OS 16x10GE MPC 또는 MPC3E 라인 카드를 포함하는 MX 시리즈 라우터에서 실행되는 릴리스 13.2 이상
Junos OS MPC4E 라인 카드를 포함하는 MX 시리즈 라우터에서 실행되는 릴리스 13.3 이상
Junos OS MPC6E 라인 카드를 포함하는 MX 시리즈 라우터에서 실행되는 릴리스 15.1 이상
개요
기본적으로 출력 스케줄링은 논리적 인터페이스에서 활성화되지 않습니다. 구성된 셰이핑이 없는 논리적 인터페이스는 기본 스케줄러를 공유합니다. 논리적 인터페이스 스케줄링 ( 단위당 스케줄링이라고도 함)을 사용하면 논리적 인터페이스에서 여러 출력 대기열을 활성화하고 각 대기열에 대해 맞춤형 스케줄링 및 셰이핑을 연결할 수 있습니다.
단위당 스케줄링을 활성화하려면 계층 수준에서 문을 [edit interfaces interface name] 포함합니다per-unit-scheduler. 유닛별 스케줄러가 활성화되면 계층 수준에서 문을 포함하여 논리적 인터페이스에 대한 전용 스케줄러를 scheduler-map [edit class-of-service interfaces interface name unit logical unit number] 정의할 수 있습니다. 또는 계층 수준에서 문을 [edit class-of-service traffic-control-profiles traffic control profile name] 포함 scheduler-map 시키고 계층 수준에서 문을 [edit class-of-service interfaces interface name unit logical unit number] 포함할 output-traffic-control-profile 수 있습니다.
이 예는 트래픽 제어 프로파일을 사용하여 논리적 인터페이스에 대한 스케줄러를 정의하는 방법을 보여줍니다.
구성
CLI 빠른 구성
이 예를 빠르게 구성하려면, 아래 명령을 복사하여 텍스트 파일로 붙여 넣은 다음 모든 라인브러브를 제거하고, 네트워크 구성을 일치하는 데 필요한 세부 사항을 변경한 다음 계층 수준에서 명령을 CLI [edit] 로 복사해 붙여 넣습니다.
