Port-security sozlanishlari haqidagi ma’lumotlarni ko`rish
switch# show port-security
switch# show port-security interface fa0/3
switch# show port-security address
Topshiriq
2.4-rasmda keltirilgan tarmoq topologiyasini Cisco
Packet Tracer dasturida
tuzish talab qilinadi;
Har bir kompyuter uchun IP manzilni sozlang va MAC manzillarni 2.2-
rasmda ko`rsatilgandek aniqlang;
Ishni bajarish tartibi
Switch>enable
Switch#configure
terminal
Switch(config)#hostname Sw1
Sw1(config)#interface fa0/1
1. Portni access rejimiga o`zgartirish
Sw1(config-if)#switchport mode
access
2. Portda port-securityni ishga tushurish
Sw1 (config-if)#switchport port-security
3. Secure-MAC ni dinamik aniqlashni ko`rsatish
Sw1 (config-if)#switchport port-security mac-address sticky
Sw1 (config-if)#exit
4. Secure-MAC ni statik aniqlashni ko`rsatish
Sw1(config)#interface fastEthernet 0/2
Sw1(config-if)#switchport mode access
Sw1(config-if)#switchport port-security
Sw1(config-if)#switchport port-security mac-address 000B.BE9B.EE4A
Sw1(config-if)#end
5. Xavfsizlik buzilishigi javob berish rejimini sozlash
Sw1(config)#interface fastEthernet 0/3
Sw1(config-if)#switchport mode access
Sw1(config-if)#switchport port-security
Sw1(config-if)#switchport port-security mac-address sticky
Sw1(config-if)#switchport port-security violation protect
Sw1(config-if)#end
6. Ishlatilmayotgan portlarni o`chirish
Sw1(config)#interface range fastEthernet 0/5-24
Sw1(config-if-range)#shutdown
7. Portda secure-MAC maksimal soni N ni ko`rsatish
(Bu buyruq Sw2
kommutatorga tavsiya etiladi)
Switch>enable
Switch#configure terminal
Switch(config)#hostname Sw2
Sw2(config)#interface fa0/4
Sw2(config-if)#switchport mode trunk
Sw2(config-if)#switchport port-security maximum 4
Sw1(config-if)#switchport port-security violation restrict
8. Natijani tekshirish
Switch#show port-security interface fa 0/1

Topshiriq
Har bir talaba yuqorida keltirilgan ma’lumotlar bo`yicha Cisco Packet tracer
muhitida laboratoriya ishini bajaradi.
Nazorat savollari
1.
MAC-manzil bu nima va qurilmalarda qanday aniqlanadi?
2.
Kommutatorda port xavfsizligi funksiyasini nima uchun ishlatiladi?
3.
Secure-MAC maksimal sonini N qaysi holatlarda ishlatiladi?
