Resum de comandes de configuració VLAN

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

Configuració ports troncals

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...
[OK]

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...
[OK]

Per assiganr adreça IP a la VLAN (Opcional)

Switch(config)#interface vlan 4
Switch(config-if)#

Switch(config-if)#no shutdown 
Switch(config-if)#do wr
