Task Command Remarks
5. Enter interface view.
• Enter Layer 2 Ethernet interface
view:
interface interface-type
interface-number
• Enter Layer 2 aggregate interface
view:
interface bridge-aggregation
interface-number
• The configurations made in Layer 2
Ethernet interface view apply only to
the port.
• The configurations made in Layer 2
aggregate interface view apply to
the aggregate interface and its
aggregation member ports. If the
system fails to apply the
configurations to the aggregate
interface, it stops applying the
configurations to the aggregation
member ports. If the system fails to
apply the configurations to an
aggregation member port, it skips
the port and moves to the next
member port.
6. Configure the port
link type as hybrid.
port link-type hybrid By default, all ports are access ports.
7. Assign the hybrid
port to the specified
IP subnet-based
VLANs.
port hybrid vlan vlan-id-list { tagged |
untagged }
By default, a hybrid port is an untagged
member of the VLAN to which the port
belongs when its link type is access.
8. Associate the hybrid
port with the
specified IP
subnet-based VLAN.
port hybrid ip-subnet-vlan vlan vlan-id
By default, no IP subnet-based VLAN is
associated with a hybrid port.
Configuring protocol-based VLANs
The protocol-based VLAN feature assigns inbound packets to different VLANs based on their protocol
types and encapsulation formats. The protocols available for VLAN assignment include IP, IPX, and AT.
The encapsulation formats include Ethernet II, 802.3 raw, 802.2 LLC, and 802.2 SNAP.
A protocol template defines a protocol type and an encapsulation format. A combination of a
protocol-based VLAN ID and a protocol index uniquely identify a protocol template. You can assign
multiple protocol templates to a protocol-based VLAN.
This feature is available only on hybrid ports, and it processes only untagged packets. It associates the
available network service types with VLANs and facilitates network management and maintenance.
A protocol-based VLAN has one or multiple protocol templates. A protocol template defines a protocol
type and an encapsulation format as the match criteria to match inbound packets. Each protocol
template has a unique index in the protocol-based VLAN. All protocol templates in a protocol-based
VLAN have the same VLAN ID.
For a port to assign inbound packets to protocol-based VLANs, perform the following tasks:
• Assign the port to the protocol-based VLANs.
• Associate the port with the protocol templates of the protocol-based VLANs.
When an untagged packet arrives at the port, the port processes the packet as follows:
