• The MAC-based VLAN feature is mainly configured on downlink ports of user access devices. Do
not enable this function together with link aggregation.
• With MSTP enabled, if a port is blocked in the MST instance (MSTI) of the target MAC-based VLAN,
the port drops received packets instead of delivering them to the CPU. As a result, the receiving port
will not be dynamically assigned to the corresponding VLAN. Do not configure dynamic
MAC-based VLAN assignment together with MSTP, because the former is mainly configured on the
access side.
• With PVST enabled, if the target MAC-based VLAN is not permitted on a port, the port is placed in
the blocked state and drops received packets instead of delivering them to the CPU. As a result, the
receiving port will not be dynamically assigned to the corresponding VLAN. Do not configure
dynamic MAC-based VLAN assignment together with PVST, because the former is mainly
configured on the access side.
Configuration procedure
This section describes the MAC-based VLAN configuration procedure.
Configuring static MAC-based VLAN assignment
Step Command Remarks
1. Enter system view. system-view N/A
2. Associate a specific MAC
address with a VLAN.
mac-vlan mac-address mac-address
[ mask mac-mask ] vlan vlan-id
[ priority priority ]
N/A
3. Enter interface view or
port group view.
• Enter interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
Use one of the commands.
• The configuration made in
Ethernet interface view applies
only to the port.
• The configuration made in port
group view applies to all ports in
the port group.
4. Configure the link type of
the ports as hybrid.
port link-type hybrid By default, all ports are access ports.
5. Configure the hybrid
ports to permit packets
from specific MAC-based
VLANs to pass through.
port hybrid vlan vlan-list { tagged |
untagged }
By default, a hybrid port only permits
packets from VLAN 1 to pass
through.
6. Enable the MAC-based
VLAN feature.
mac-vlan enable
By default, MAC-based VLAN is
disabled.
7. Configure VLAN
matching precedence.
vlan precedence { mac-vlan |
ip-subnet-vlan }
Optional.
By default, VLANs are preferably
matched based on MAC addresses.
