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
29
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)
