DISACARD CONFIGURATION

Cara Mendiscard Configurasi: Artinya ketika melakuka beberapa konfigurasi yang sudah dilakuak, ternayat pengen dibatalkan.

Ex:

root@R-02# edit interfaces ge-0/0/3
[edit interfaces ge-0/0/3]
root@R-02# set unit 0 family inet address 172.16.0.254/24

[edit interfaces ge-0/0/3]
root@R-02#

[edit interfaces ge-0/0/3]
root@R-02# top

root@R-02# set system login user aguna1 class super-user

Lalu Verifrikasi:

root@R-02# show | compare
[edit interfaces]
+ ge-0/0/3 {
+ unit 0 {
+ family inet {
+ address 172.16.0.254/24;
+ }
+ }
+ }

[edit]
root@R-02#

Dari Verifikasi bahwa ada tanda (+) artinya penambahan konfigurasi sebagai "kandidat configurasi". Maka untuk membatalkan / menghapus cukup dilakukan dengan perintah rollback 0.

root@R-02#rollback 0

Active & Deactive

root@R-1# run show interfaces terse
Interface Admin Link Proto Local Remote
ge-0/0/0 up up
ge-0/0/0.0 up up inet 12.12.12.1/30
ge-0/0/1 up up
ge-0/0/1.0 up up inet 192.168.1.254/24

Lalu interface ge-0/0/1 kita mau non-aktifkan. Berikut commandnya.
Noted: pastikan sebelmnya masih bisa ping dari R2 / router tetangga.

root@R-1# deactivate interfaces ge-0/0/1
root@R-1# commit

Jika ingin meng-aktifkan kembali, cukup dengan perintah berikut:
root@R-1# activate interfaces ge-0/0/1
root@R-1# commit

Mk interface ge-0/0/1 sudah aktifi Kembali dan bisa di ping.

RENAME Configuration

root@R-1# show system login
user aguna2 {
uid 2000;
class super-user;
authentication {
encrypted-password "$1$dnKAYQMY$6WNCkNlOwVFAabx/Q0GoE/"; ## SECRET-DATA
}
}
-----
Lalu re-name user aguna2 menjadi user aguna1

root@R-1# edit system login
root@R-1# rename user aguna2 to user aguna1
-----
root@R-1# show | compare
[edit system login]
+ user aguna1 {
+ uid 2000;
+ class super-user;
+ authentication {
+ encrypted-password "$1$dnKAYQMY$6WNCkNlOwVFAabx/Q0GoE/"; ## SECRET-DATA
+ }
+ }
- user aguna2 {
- uid 2000;
- class super-user;
- authentication {
- encrypted-password "$1$dnKAYQMY$6WNCkNlOwVFAabx/Q0GoE/"; ## SECRET-DATA
- }
- }

Replace Pattern : Tujuannya mengganti kata aguna ke login
root@R-1# show
user aguna1 {
uid 2000;
class super-user;
authentication {
encrypted-password "$1$dnKAYQMY$6WNCkNlOwVFAabx/Q0GoE/"; ## SECRET-DATA
}
}
user aguna2 {
uid 2001;
class super-user;
authentication {
encrypted-password "$1$fqAqqIFw$nwp2SMMdAFynzLTbukJAd."; ## SECRET-DATA
}
}
-------------BERIKUT COMMANDNYA----------
root@R-1# edit system login
root@R-1# replace pattern aguna1 with login1
root@R-1# commit
--------------------END---------------------
VERIFIKASI:
root@R-1# show system login
user login1 {
uid 2000;
class super-user;
authentication {
encrypted-password "$1$dnKAYQMY$6WNCkNlOwVFAabx/Q0GoE/"; ## SECRET-DATA
}
}
user login2 {
uid 2001;
class super-user;
authentication {
encrypted-password "$1$fqAqqIFw$nwp2SMMdAFynzLTbukJAd."; ## SECRET-DATA
}
}

REPLACE & RENAME

RENAME user : misalnya username aguna3 diganti aguna 4
aguna@R-Juniper-01# edit system login
aguna@R-Juniper-01# rename user aguna3 to user aguna4

REPLACE Username ( replace)
aguna@R-Juniper-01# edit system log
aguna@R-Juniper-01# replace pattern aguna2 with aguna22

aguna@R-Juniper-01# replace pattern 192.168.1.254/24 with 192.168.2.254/24

RESCUE

root> request system configuration rescue save
conf t
delete
[yes]

#show system configuration rescue
!
#commit
Noted: maka hasilnya adalah tidak bisa deleted, karna mode rescue sdh diaktifkan

#rollback rescue
#commit
noted: stelh rollback baru bisa di rollback

----------------SELESAI----------------------------

Lakukan Save Konfig

root@R-01# save config-01-11-2025

Tambah satu konfigurasi di interface ge-0/0/01

root@R-01# set interfaces ge-0/0/01 unit 0 family inet address 192.168.1.254/24

Lalu Verifikasi, ada tanda + artinya bahwa ada tambahn konfigurasi yg blum di commit.

root@R-01# show | compare config-01-11-2025
[edit interfaces]
+ ge-0/0/1 {
+ unit 0 {
+ family inet {
+ address 192.168.1.254/24;
