Juniper CLI Mode

1. Juniper CLI Mode

• Prompt를 확인하여 현재 CLI Mode 확인 가능
• 'quit' 또는 'exit' 명령을 통해 'Configuration Mode → Operational Mode → Shell Mode'로 이동 가능

1) % : Shell Mode

• 일반적으로 'root' 계정으로 접속해야 'Shell Mode'로 접속 가능
  
  • root가 아닌 다른 계정도 충분한 권한을 가지면 'Shell Mode'로 접속 가능
• 'cli' 명령어를 입력하여 'Operational Mode'로 이동 가능

root@vMX1:/ # cli 
root@vMX1>

• Linux 명령어 사용 가능

root@vMX1:/ # pwd
/
root@vMX1:/ # 
root@vMX1:/ # ls -la

2) > : Operational Mode

• 'configure' 명령어를 입력하여 'Configuration Mode'로 이동 가능

root@vMX1> configure 
Entering configuration mode

[edit]
root@vMX1#

• 'show' 명령을 통해 Resource 사용률, Hardware 정보, Software 정보, Log, Table 등 여러 정보 확인 가능
• 'request' 명령을 통해 시스템 종료 및 재부팅, 프로세스 중지 및 재시작과 같은 요청이 가능
• 'monitor' 명령을 통해 대략적인 문제 진단 가능
• 'ssh' 및 'telnet' 명령을 통해 원격 접속 가능

 

3) # : Configuration Mode

• 'run' 명령어를 가장 앞에 추가하여 'Operational Mode'처럼 동작 가능
  • Cisco Vendor의 'do' 명령과 비슷한 역할

root@vMX1# run show configuration | display set 
set version 18.2R1.9
set system root-authentication encrypted-password "$6$jxakq45s$Inq0exINk7FPg1dPZDQroB4EdqB0TnLZicQaE4GNX/oM0O9bIeBtr2nUvDb85If7euMket.XUK6x5WFKa264I1"

• 'set' 명령을 통해 장비 동작에 관련된 설정 추가 및 변경(IP, VLAN, Routing) 가능
• 'delete' 명령을 통해 'set'으로 설정한 값을 제거 가능
• 최대 32명의 사용자가 동시에 Configuration Mode에 존재 가능
