To do...
Allow the specified VLANs to
pass through the current
Trunk port
Configure the default VLAN
for the Trunk port
To convert a Trunk port into a Hybrid port (or vice versa), you need to use the
■
Access port as a medium. For example, the Trunk port has to be configured as
an Access port first and then a Hybrid port.
The default VLAN IDs of the Trunk ports on the local and peer devices must be
■
the same. Otherwise, packets cannot be transmitted properly.
A Hybrid port may belong to multiple VLANs, and this configuration can only be
performed in Ethernet port view or port group view.
Follow these steps to configure the Hybrid-port-based VLAN:
To do...

To configure a Trunk port into a Hybrid port (or vice versa), you need to use the
■
Access port as a medium. For example, the Trunk port has to be configured as
an Access port first and then a Hybrid port.
Ensure that the VLANs already exist before configuring them to pass through a
■
Hybrid port.
The default VLAN IDs of the Hybrid ports on the local and the peer devices
■
must be the same. Otherwise, packets cannot be transmitted properly.

Remarks
Required
By default, all Trunk ports only
allow packets of VLAN 1 to
pass.
VLAN 1 is the default by
default.
Remarks

Use either command;
In Ethernet port view, the
subsequent configurations
