Hostname vermemiz gerekli şart değil ama iyi olur.

Ilk görünüş şöyle iki networkümüz var ve switchlerde gigabit portlar Router R1 in iki gigabit portuna bağlı.

Router>enable
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#enable password cisco
Router(config)#line vty 0 4
Router(config-line)#password cisco

öncelikle enable işlemi her geldiğinde bundan sonra password soracak.

Ayrıca her konsol kablosu bağlantısında da password soracak (confıg-line)

Ve max 5 adet konsol enable edilmiş durumda

Şimdi ilk arayüzü ayarlayalım

Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#int giga
Router(config)#int gigabitEthernet 0/0
Router(config-if)#ip add
Router(config-if)#ip address  192.168.1.1 255.255.255.0
Router(config-if)#no sh

kısaca diğerini de ayarlayalım

Router(config-if)#exit
Router(config)#int gi 0/1
Router(config-if)#ip ad
Router(config-if)#ip address 192.168.2.1 255.255.255.0
Router(config-if)#no sh

Önemli konulardan biri de description yazmak böylece hangisi nereye bağlı biliriz.

Router(config-if)#description to LAN1

Duruma bakalım kısaca

Router#show ip interface brief
Interface              IP-Address      OK? Method Status                Protocol
