To do… Use the command… Remarks
Assign the trunk port(s) to the
specified VLAN(s)
port trunk permit vlan
{ vlan-id-list | all }
Required
By default, a trunk port carries only
VLAN 1.
Configure the default VLAN of
the trunk port(s)
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 details about the port
link-type command, see VLAN Commands in the Layer 2 - LAN Switching Configuration Guide.
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 simply skips the port and moves to the
next port.
Assigning a Hybrid Port to a VLAN
A hybrid port can carry multiple VLANs. You can assign it to a VLAN in interface view (including
Ethernet interface view, Layer 2 aggregate interface view) or port group view.
Follow these steps to assign a hybrid port to one or multiple VLANs:
