Follow these steps to assign a hybrid port to one or multiple VLANs:
To do...
Enter system view
Enter Ethernet
interface view
Enter Layer-2
aggregate
interface view
Enter
interface
view or port
group view
Enter port
group view
Configure the link type of the
port(s) as hybrid
Assign the hybrid port(s) to
the specified VLAN(s)
Configure the default VLAN of
the hybrid port
To change the link type of a port from trunk to hybrid or vice versa, you must set the link type to
access first.
Before assigning a hybrid port to a VLAN, create the VLAN first.
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 Access Volume.
After configuring the default VLAN for a hybrid port, you must use the port hybrid vlan command
to configure the hybrid 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 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.
Use the command...

Remarks
—
Required
Use either command.
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,
subsequent configurations
apply to the Layer-2
aggregate interface and all
its member ports.

Required
By default, a hybrid port allows
only packets of VLAN 1 to pass
through untagged.
Optional
VLAN 1 is the default by
default.
