below commands could be any VLAN
number or list of VLAN numbers.
Multiple VLAN numbers can be

Step 4a
switchport trunk allowed vlan <vlan-list>
This command configures the list of
allowed VLANs on this trunk. Only the
VLANs provided on the vlan-list will be
carried over the trunk.
Step 4b
switchport trunk allowed vlan add <vlan-list>
This command adds the given list of
VLANS to the existing set of allowed
VLANs on this trunk.
Step 4c
switchport trunk allowed vlan remove <vlan-list>
This command removes the given list of
VLANS from the existing set of allowed
VLANs on this trunk.
Step 4d
switchport trunk allowed vlan except <vlan-list>
This command makes all the configured
VLANs allowed on this trunk except for
the given list of VLANs.
Step 4e
switchport trunk allowed vlan all
This command sets the default
behavior of allowing all VLANs
configured in the switch as allowed
VLANs on this trunk.

Step 5
show vlan port config port <iftype> <ifnum>
and
show running-config

Step 6
write startup-config
Optional step – saves this VLAN

The “switchport trunk allowed vlan …” commands will be accepted only if the port is in trunk
mode.
A trunk port will not carry traffic for any VLANs that are not configured in the switch.
For example, if a user wants to allow traffic for VLANs 1 to 100, VLANs 1 to 100 need to be
created in the switch using the “vlan” command.
The examples below show examples of configurations to allow VLANs on trunk ports.
Configure to allow only VLANs 2 to 20 on trunk interface fx 0/1.
SMIS# configure terminal
SMIS(config)# vlan 2-20
SMIS(config-vlan)# exit
