Лабораторная работа №12 Конфигурация свитча

Свитч 4:

%LINK-3-UPDOWN: Interface FastEthernet0/1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up

%LINK-3-UPDOWN: Interface FastEthernet0/12, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/12, changed state to up

Из панели инструментов выбираем свитч 4. Присваиваем ему имя хоста 2950sw4 и пароль cisco. Назначаем IP адрес 197.10.1.100/24 и маску подсети 197.10.1.1.
