A CLI DO JUNOS (COMMAND LINE INTERFACE)

Fazendo login

O primeiro passo para acessar a interface CLI é fazer o processo de login.

O Junos requer um “username” e “password” para prover acesso ao sistema. O administrador do sistema cria contas de usuário root configurada de fábrica, sem senha. É recomendado que essa senha seja configurada logo no primeiro acesso.

Ao se conectar no equipamento, o usuário recebe um prompt que mostra o nome do usuário e “hostname” do roteador (caso haja um configurado).

Processo de login:

host (ttyu0)

login: user

Password:

--- JUNOS 9.5R1.8 BUILT 2009-04-13 20:03:09 UTC

user@host>

O usuário root tem acesso complete a todas as funções do roteador. Quando se faz o login utilizando o usuário root, tem-se acesso a um shell de Unix. Para iniciar a CLI do Junos utiliza-se o comando “cli”. Para terminar a sessão usa-se o comando “exit”.

Todos os demais usuários (não root) ao se conectarem no sistema já recebem a CLI do Junos, sem necessidade do comando “cli”.

test interface ds0-bert-startSyntax test interface ds0-bert-start ds-fpc/pic/portRelease Information Command introduced before Junos OS Release 7.4.Description Start a bit error rate test (BERT) on a DS0 interface.Options ds-fpc/pic/port—DS0 interface name.

Additional Information Before starting a BERT, you must disable the interface. To do so, include the disablestatement at the [edit interfaces interface-name] hierarchy level. You can run a BERT ononly one interface per PIC at a time.Required PrivilegeLevelviewList of Sample Output test interface ds0-bert-start on page 35Output Fields To display the results of the BERT, use the show interfaces extensive command.Sample Outputtest interfaceds0-bert-startuser@host> test interface ds0-bert-start ds-1/0/0Copyright
