3.Tekshirib ko’ramiz

Telnet protokoli
Ishni bajarish tartibi
1.Routerni sozlaymiz:
Router>enable
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int GigabitEthernet 0/0
Router(config-if)#no shutdown

Router(config-if)#

%LINK-5-CHANGED: Interface GigabitEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to up

Router(config-if)#ip address 192.168.10.1 255.255.255.0

Router(config-if)#exit
Router(config)#line vty 0 15
Router(config-line)#password alik
Router(config-line)#end
Router#

2.Kompyuterlarga ip manzil beramiz:



3.Tekshirib ko’ramiz:
