Per arribar a configurar que un enllaç és per a una VLAN
Switch#conf t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#vlan 2 Switch(config-vlan)#name VLAN2 Switch(config-vlan)#vlan 3 Switch(config-vlan)#name VLAN3 Switch(config-vlan)#vlan 4 Switch(config-vlan)#name ADMINISTRACIO Switch(config-vlan)#exit
Assignar un rang de ports a una VLAN
Switch(config)#interface range fastEthernet 0/1-10 Switch(config-if-range)#switchport mode access Switch(config-if-range)#switchport access vlan 2 Switch(config-if-range)#exi Switch(config)#interface range fastEthernet 0/11-23 Switch(config-if-range)#switchport mode access Switch(config-if-range)#switchport access vlan 3 Switch(config-if-range)#ex Switch(config)#interface fastEthernet 0/24 Switch(config-if)#switchport mode access Switch(config-if)#switchport access vlan 4 Switch(config-if)#ex Switch(config)#interface range gigabitEthernet 0/1-2 Switch(config-if-range)#switchport mode trunk Switch(config-if-range)#switchport trunk allowed vlan 2,3-4 Switch(config-if-range)#switchport trunk native vlan 99 Switch(config-if-range)#do wr Building configuration...

Per modificar la configuració dels ports troncals
Switch(config)#interface range gigabitEthernet 0/1-2 Switch(config-if-range)#switchport trunk allowed vlan ? WORD VLAN IDs of the allowed VLANs when this port is in trunking mode add add VLANs to the current list all all VLANs except all VLANs except the following none no VLANs remove remove VLANs from the current list Switch(config-if-range)#switchport trunk allowed vlan remove ? <1-4094> VLAN ID of a allowed VLAN when this port is in trunking mode Switch(config-if-range)#switchport trunk allowed vlan remove 2 Switch(config-if-range)#switchport trunk allowed vlan add 2 Switch(config-if-range)#do wr Building configuration...
