Interface configuration mode.
Native VLAN:
A trunk port belongs to one native VLAN. A native VLAN means that the untagged packets
received/sent on the trunk port belong to the VLAN. Obviously, the default VLAN ID of the interface
(that is, the PVID in the IEEE 802.1Q) is the VLAN ID of the native VLAN. In addition, when frames
belonging to the native VLAN are sent over the trunk port, they are untagged.
Allowed-VLAN List:
By default, a trunk port sends traffic to and received traffic from all VLANs (ID 1 to 4094). However,
you can prevent the traffic from passing over the trunk port by configuring allowed VLAN lists on a
trunk port .
Use the show interfaces switchport command to display configuration.
The example below removes port 1/15 from VLAN 2:
Ruijie(config)# interface fastethernet 1/15
Ruijie(config-if)# switchport trunk allowed vlan remove 2
Ruijie(config-if)# end
Ruijie# show interfaces fastethernet1/15 switchport
