ONFIGURATION
A Hybrid port may belong to multiple VLANs, and this configuration can only be
performed in Ethernet port view.
Follow these steps to configure the Hybrid-port-based VLAN:
To do...
Enter system view
Enter Ethernet port view
Configure the port link type
as Hybrid
Configure the default VLAN
of the Hybrid port
Allow the specified VLANs to
pass through the current
Hybrid port
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.
A Trunk port may belong to multiple VLANs, and you can only perform this
configuration in Ethernet port view.
Follow these steps to configure the Trunk-port-based VLAN:
To do...
Enter system view
Enter Ethernet port view
Configure the port link type
as Trunk
Configure the default VLAN
for the Trunk port
Allow the specified VLANs to
pass through the current
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.
