----------------------------------------------------------------------------------------------------------------------
1.Unix Mode (tidak bisa lakukan akses konfigurasi router)
root@% ls
root@% pwd
root@% cd /
root@% cd /root/
2.Operational Mode (bs melakukan monitoring, ntuk melihat konfigurasi coomand
apa sj yg kt lakukan, i.e ping, )
Untuk masuk confogurasi operation mode gunakan cli
root@%cli
root>show interface ters
root>show
root>show
3.Configuration Mode / Edit Mode (bs melakukan untuk melakukan konfigurasi di Juniper )
root> configure
root# set system root-authentication plain-text-password
------------------------------------------------
Configure Ada 3 mode:
1. Configure Biasa: (bebberapa user akses ruter yg sama diwaktu yg sama, ada 1 user commit konfig, mk user yg lain bakal ikut ke commit konfigurasi kandidat nya.
2. Configure Private
- Multiple user bisa login secara waktu bersamaan ke Junos, dan masing-masing user meiliki changes sendiri dan commit sendiri.
- Jika user A melakukan changes dan commit mk user lai tdk akan ikut ter-commit,
- Kekekuranganya tdk bisa melkukan commit confirmed
root@R-01> configure private
------------------------------------------------
3.Configure Exclusive :
- Hanya bisa satu user yg di ijinkan untuk melakukan konfigurasi.
- Jika ada user lain misal user root sedang melakukan configure exclusive, maka user lain yang login.remote tidak bisa melakuak configure , akan ada muncul error.
- Jika user user ingin melakukan konfigurasi maka user lain yg sedang login tersebut bisa dipaksa keluar menggunakan perintah sistem keluar, yaitu dengan command sbb:
(hanya boleh config dan commit hanya 1 user/orang, harus kluar dl baru user yg lain bisa config).
root@R1# run request system reboot
REPLACE (sepesifik):
root@R1# replace pattern 12.12.12.1/24 with 12.12.12.2/2
RENAME
rename interfaces ge-0/0/0.0 family inet address 12.12.12.1/24 to address 12.12.12.2/2
RESTART / SHUTDOWN
root@R2> request system power-off
root@R2> request system reboot
RESET FACTORY
root@R2> request system zeroize
root@R2# load factory-default
fungsinya setinganya doang direset ke factory reset. cara ini masih bs rollback

set interfaces ge-0/0/0 unit 0 family inet address 192.168.2.254/24
set interfaces ge-0/0/0 unit 0 family inet address 12.12.12.2/30

R-02# run show configuration | no-more
R-02# run show configuration | display set | no-more

R-02> show configuration interfaces ge-0/0/0
R-02> show configuration interfaces ge-0/0/0 | display set
R-02> show configuration protocols bgp | display set
R-02> show configuration | display set
VERIFIKASI:
R-02# run show configuration interfaces ge-0/0/1 | display set
R-02# set interfaces ge-0/0/1 unit 0 family inet address 192.168.1.254/24
Kemudian, kita lakukan edit
R-02# edit interfaces ge-0/0/1
R-02# insert unit 0 family inet address 192.168.2.254/24
aguna@R-Juniper-02# commit
commit complete
R-02# insert interfaces ge-0/0/1 unit 0 family inet address 192.168.3.254/24 before address 192.168.2.254/24
Kemudian Edit IP
Misalnya IP sebelumnya 192.168.22.254/24, diganti ke IP 192.168.2.254/24
root@R-02# edit address 192.168.22.254/24
root@R-02# commit
Hapus IP Interface
root@R-02# delete interfaces ge-0/0/1 unit 0 family inet address 192.168.2.254/24
root@R-02# commit
