Trunk port configuration example to carry the different VLAN tags between two devices on the same physical link. Vendor agnostic technology (IEEE 802.1Q)
Switch(config)# interface GigabitEthernet 0/0/10
Switch(config-if)# switchport trunk encapsulation dot1q
Switch(config-if)# switchport mode trunk
By default this configuration allows all VLANs to be transmitted over the trunk link. To restrict the link to carry only specified VLANs use the allowed vlan command
Switch(config)# interface GigabitEthernet 0/0/10
Switch(config-if)# switchport trunk allowed vlan 1,2,3,4
To verify how the trunk port is configured you can issue few show commands:
Switch# show run interface GigabitEthernet 0/0/10
Switch# show interface trunk
Check how to configure access port.
