Switch VLAN and VLAN Trunk Configuration

Switch VLAN syntax:
switch(config)# interface type module/number
switch(config-if)# switchport 
! switchport command configures the port for layer 2 operation
switch(config-if)# switchport mode access
switch(config-if)# switchport access vlan vlan-num

VLAN Trunking Configuration
switch> enable
switch# configure terminal
switch(config)# interface type mod/port
switch(config-if)# switchport!switch port must be in Layer 2 mode before it can supporta trunk
switch(config-if)# switchport trunk encapsulation {isl | dot1q | negotiate}
switch(config-if)# switchport trunk native vlan vlan-id
!native vlan only for dot1q encapsulation
!identifying the untagged or native VLAN number as vlan-id (1 to 4094)
!ISL doesn't support an untagged VLAN
switch(config-if)# switchport trunk allowed vlan {vlan-list | all | <add | except | remove> vlan-list}
switch(config-if)# switchport mode {trunk | dynamic <desirable | auto>}
