Trunk mode
A trunk port can be a member of multiple VLANs set up on an interface. A trunk port transmits trac for all VLANs. To transmit trac on a
trunk port with multiple VLANs, OS10 uses tagging or the 802.1q encapsulation method.
1 Congure a port in INTERFACE mode.
interface ethernet node/slot/port[:subport]
2 Change Switchport mode to Trunk mode in INTERFACE mode.
switchport mode trunk
3 Enter the allowed VLANs on the trunk port in INTERFACE mode.
switchport trunk allowed vlan vlan-id
Congure port in Trunk mode
OS10(config)# interface ethernet 1/1/6
OS10(conf-if-eth1/1/6)# switchport mode trunk
OS10(conf-if-eth1/1/6)# switchport trunk allowed vlan 108

Assign IP address
You can assign an IP address to each VLAN to make it a L3 VLAN. All the ports in that VLAN belong to that particular IP subnet.
The trac between the ports in dierent VLANs route using the IP address. Congure the L3 VLAN interface to remain administratively UP
or DOWN using the shutdown and no shutdown commands. This provisioning only aects the L3 trac across the members of a
VLAN and does not aect the L2 trac.
You must not assign an IP address to the default VLAN (VLAN 1).
