Configuring and Enabling Switch Ports as Trunk Ports
This procedure describes how to create a trunk port that can carry multiple VLANs using 802.1Q
tagging. Trunk mode is available only with the Security Plus license.
To create an access port, where an interface is assigned to only one VLAN, see the
Enabling Switch Ports as Access Ports" section on page
Guidelines
This switch port cannot pass traffic until you assign at least one VLAN to it, native or non-native.
Detailed Steps
Command
Step 1
interface ethernet0/port
Example:
hostname(config)# interface ethernet0/1
Step 2
To assign VLANs to this trunk, do one or more of the following:
switchport trunk allowed vlan vlan_range
Example:
hostname(config)# switchport trunk allowed
vlan 100-200
If you want to configure a switch port as a trunk port, see the
Ports as Trunk Ports" section on page
To complete the interface configuration, see
(Routed Mode)," or Chapter 1, "Completing Interface Configuration (Transparent Mode)."

1-7.
Purpose
Specifies the switch port you want to configure, where port is 0
through 7.
Identifies one or more VLANs that you can assign to the trunk
port, where the vlan_range (with VLANs between 1 and 4090)
can be identified in one of the following ways:
•
A single number (n)
•
A range (n-x)
•
Separate numbers and ranges by commas, for example:
5,7-10,13,45-100
You can enter spaces instead of commas, but the command is
saved to the configuration with commas.
You can include the native VLAN in this command, but it is not
required; the native VLAN is passed whether it is included in this
command or not.
