Набрать enableдля того, чтобы оказаться в привилегированном режиме. Знак (#) оповещает о том, что вы находитесь в привилегированном режиме.

Router>enable

Для выхода из этого режима disable, и снова в пользовательском режиме.

Router#disable

Router>enable

Команда configure terminal служит для входа в режим конфигурации терминала.

Router#configure terminal

Enter configuration commands, one per line. EndwithCNTL/Z.

После входа в режим конфигурации нужно задать имя хоста маршрутизатора 1 командой hostname

Router(config)#hostname router1

router1(config)#enable ?

password Assign the privileged level password

secret Assign the privileged level secret

Устанавливаем пароли: допускающийся пароль ccnalab, который будет файлом конфигурации маршрутизатора и допустимый пароль cisco, который будет зашифрован.

router1(config)#enable password 123

router1(config)#enable secret cisco

Необходимо присвоить ip адрес для маршрутизатора 1 интерфейс Ethernet0(Ip адрес и маска даны в таблице).

router1(config)#interface Ethernet0

router1(config-if)#ip address 160.10.1.1 255.255.255.0

router1(config-if)#no shutdown

%LINK-3-UPDOWN: Interface Ethernet0, changed state to up

router1(config-if)#exit

Необходимо присвоить ip адрес для маршрутизатора 1 интерфейс Serial0. Для выхода из режима конфигурирования можно с помощью команды ctrl-z.

router1(config)#int s0

router1(config-if)#ip address 175.10.1.1 255.255.255.0

router1(config-if)#no shutdown

%LINK-3-UPDOWN: Interface Serial0, changed state to up

%LINK-3-UPDOWN: Interface Serial0, changed state to down

%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to down

router1(config-if)#^Z

%SYS-5-CONFIG_I: Configured from console by console

Ввести logout чтобы выйти в пользовательский режим

router1#logout

Router con0 is now available

Press RETURN to get started.

Нажимаем ЕNTER и попадаем в пользовательский режим и печатаем enable для привилегированного режима, вводим секретный пароль cisco.
