1. Introduction to Traceoption
1) Introduction to Traceoption
- Cisco Vendor의 Debugging과 유사한 기능
- Juniper 장비의 Background Process 또는 Traffic Flow 모니터링 가능
- 인터페이스, 프로토콜, 기타 여러 Context에서 사용 가능
2) How to configuration Traceoptions
- Traceoption을 구성하기 위해 File 및 Flag 정의가 필요
- File Option을 사용하여 모니터링 정보의 출력물이 저장될 File Name, File Maximum Size, File Count를 구성
- Flag Option을 사용하여 모니터링할 부분을 지정
- Traceoption을 구성하려면 Debug 하려는 Background Process 또는 Traffic Flow의 Context로 진입
- Ex) 인터페이스 관련 정보를 Debug하려면 Interface Context로 진입 후, Traceoption을 구성
- Traceoption 사용 시, 많은 용량을 차지할 수 있으므로 사용하지 않을 때는 Deactivate 또는 Delete하는 것을 권장
3) Example of configuring Traceoptions

< Traceoption File 구성 >
set interfaces traceoptions file FILENAME
→ File Name 설정
set interfaces traceoptions file size 10000000
→ File Size 설정(10Mbyte)
set interfaces traceoptions file files 10
→ 결과를 저장하는 File 개수 설정
< Traceoption Flag 구성 >
set interfaces ge-0/0/1 traceoptions flag all
root@R1> show log FILENAME
