In tagged mode, a port forwards frames without removing their tags. This is applicable
to scenarios in which Layer 2 Ethernet ports are connected to switches.
– (Optional) Run the port hybrid pvid vlan vlan-id command to specify the default VLAN
of a hybrid interface.
By default, all ports are added to VLAN 1.

3.3.3 Dividing a LAN into VLANs Based on MAC Addresses
MAC address-based VLAN division is used if user locations do not need to be concerned. This
improves security and flexibility for terminal users.
Context
VLANs configured based on MAC addresses process only untagged frames, and treat tagged
frames in the same manner as VLANs configured based on ports.
After receiving an untagged frame, a port searches for a MAC-VLAN mapping based on the
source MAC address in the frame.
l If a mapping is found, the port forwards the frame based on the VLAN ID and priority
value in the mapping.
l If no matching mapping is found, the port matches the frame with other matching rules.
The configuration roadmap is as follows:
1. Create VLANs.
2. Map MAC addresses to VLAN IDs.
3. Configure the port type and features.
(1) Set the port type to hybrid.
(2) Configure a port to allow frames with specified VLAN IDs to pass through.
4. (Optional) Configure the highest priority for MAC address-based VLAN division.
NOTE
By default, MAC address-based VLAN division is set as the preference. To use IP subnet-based
VLAN division, set a higher priority for it.
5. Enable MAC address-based VLAN division.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
vlan vlan-id
A VLAN is created, and the VLAN view is displayed. If the specified VLAN has been created,
the VLAN view is directly displayed.
