Step Command
Remarks
5.
Configure the hybrid port
to forward packets from
the MAC-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.
6.
Enable the MAC-based
VLAN feature.
mac-vlan enable
By default, this feature is disabled.
7.
(Optional.) Configure
VLAN matching order.
vlan precedence { mac-vlan |
ip-subnet-vlan }
By default, the system assigns
VLANs based on the MAC
address preferentially.
Configuring dynamic MAC-based VLAN assignment
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create a MAC-to-VLAN
entry.
mac-vlan mac-address mac-address
vlan vlan-id [ dot1q priority ]
The VLAN assignment for a port is
triggered only when the source
MAC address of its receiving packet
exactly matches the MAC address
in the MAC-to-VLAN entry.
3.
Enter Layer 2 Ethernet
interface view.
interface interface-type
interface-number
N/A
4.
Configure the link type of
the port as hybrid.
port link-type hybrid
By default, all ports are access
ports.
5.
Enable the MAC-based
VLAN feature.
mac-vlan enable
By default, MAC-based VLAN is
disabled.
6.
Enable dynamic
MAC-based VLAN
assignment.
mac-vlan trigger enable
By default, dynamic MAC-based
VLAN assignment is disabled.
7.
(Optional.) Configure
VLAN matching order.
vlan precedence { mac-vlan |
ip-subnet-vlan }
By default, the system assigns
VLANs based on the MAC address
preferentially..
When you enable dynamic
MAC-based VLAN assignment,
H3C recommends that you
configure the vlan precedence
mac-vlan command to ensure the
priority of MAC-based VLAN
matching. If you execute the vlan
precedence ip-subnet-vlan
command, the command will not
take effect.
8.
(Optional.) Disable the port
from forwarding packets
that fail the exact MAC
address match in its PVID.
port pvid forbidden
By default, when a port receives
packets whose source MAC
addresses fail the exact match, the
port forwards them in its PVID.
