• In Ethernet interface view, the
subsequent configurations apply
to the current port.
• In port group view, the
subsequent configurations apply
to all ports in the port group.
• In Layer 2 aggregate interface
view, the subsequent
configurations apply to the Layer
2 aggregate interface and all its
member ports.
3. Configure the link type of the
port or ports as trunk
port link-type trunk Required.
4. Assign the trunk ports to the
specified VLANs
port trunk permit vlan { vlan-id-list
| all }
Required.
By default, a trunk port carries only
VLAN 1.
5. Configure the default VLAN
of the trunk ports
port trunk pvid vlan vlan-id
Optional.
VLAN 1 is the default VLAN by
default.
To change the link type of a port from trunk to hybrid or vice versa, you must set the link type to access
first.
After configuring the default VLAN for a trunk port, you must use the port trunk permit vlan command to
configure the trunk port to allow packets from the default VLAN to pass through, so that the egress port
can forward packets from the default VLAN.
After you use the port link-type { access | hybrid | trunk } command to change the link type of an
interface, the loopback detection action configured on the interface with the loopback-detection action
command will be restored to the default. For more information about the loopback-detection action
command, see the Layer 2—LAN Switching Command Reference.
After you configure a command on a Layer 2 aggregate interface, the system starts applying the
configuration to the aggregate interface and its aggregation member ports. If the system fails to do that
on the aggregate interface, it stops applying the configuration to the aggregation member ports. If it fails
to do that on an aggregation member port, it skips the port and moves to the next port.
Assigning a hybrid port to a VLAN
A hybrid port can carry multiple VLANs. Assign it to a VLAN in interface view (including Ethernet
interface view, Layer 2 aggregate interface view) or port group view.
To assign a hybrid port to one or multiple VLANs:
