Juniper error missing mandatory statement ‘root-authentication’ | requie change of case, digit or punctuation
Quando você vai fazer seus primeiros testes virtualizando o juniper, no meu caso usei a versão 12.1R1.9 que tem na internet de monte para download, basta jogar dentro do virtual box adicionar interfaces, clonar trocar o mac das interfaces e ser feliz.
Um erro comum tentar dar o commit ( wr do cisco) após fazer suas configurações e receber o erro abaixo: missing mandatory statement ‘root-authentication’ esse erro ocorre por que é mandatório adicionar uma senha de autenticação root com o comando set system root-authentication plain-text-password “senha” após isso você pode dar commit tranquilamente.
Dica: quando você está em modo configure faz muita falta o comando “do” da cisco o comando relativo a “do” em Juniper é “run”
Configuration on juniper in gns3:
Error Message detail:
Junos version= JunOS Olive 12.1R1.9
error messge= missing mandatory statement ‘root-authentication’
error image=
The reason or causes of this error:
juniper router running JunOs have the default user name “root” with not password. Whenever you want to commit or save some changes/configuration using commit command & no password is set for root user then it will show you the above error that is “missing mandatory statement ‘root-authentication’ ”
How to save current configuration on Juniper:
In order to commit change or for saving current configuration on juniper router you have to set the root password. You can set the root password on juniper router with following commands:
cli
configure
set system root-authentication plain-text-password (press enter)
now type the root password and press enter. Remember you are required to set a strong password with alpha numeric characters otherwise it will show you error messages
error: minimum password length is 6
error: requie change of case, digit or punctuation
and you will need another try with a password having letters and numbers..
once you have successfully set root password, now you will able to save the current configurations & your commit command will also works fine.

Juniper Básico – Juniper commands | Most basic CLI Commands list for JunOS Router
Olá pessoal, como alguns dos routers que trabalho no dia dia passaram a ser juniper também além de cisco tive que correr atrás e é bem diferente os command line, a idéia geral é a mesma interfaces/protocolos/ativar serviços na caixa XYZ… não importa o vendor é sempre assim com Juniper não foi diferente, abaixo o primeiro tutorial que segui com ele aprende o básico do básico em Juniper.
Usei o virtual box com uma imagem.ova do juniper e joguei dentro do gns3, se fosse cisco eu até faria as traduções mas Juniper toda documentação é 100% inglês então nem comece se você não está aberto ao inglês, claro que estamos falando de inglês básico não precisa ser fluente…
Me comprometo em breve em por mais infos sobre, eu mesmo ainda estou em study mode 😉 adiciono também alguma dicas do franco abaixo abs…

root>
How to access configuration mode on Juniper:
You can enter into configuration mode by typing configure in configuration mode.
root> configure ((Dica do Franc0)igual o conf t do cisco)

(Dica do Franc0)Dentro do configure, diferente do cisco você não entra na interface como no cisco exemplo interface fast0/0, e dentro ip address 10.0.0.1 255.255.255.0, no juniper você usa o SET e após o ip coloca a mascara /24, unit é a unidade exemplo 0, family é a familia de ip pode ser ipv4 ipv4 para ipv4 use inet.
