GS752TXS and GS728TXS Smart Switches MAC-Based VLAN The MAC-based VLAN feature allows incoming untagged packets to be assigned to a VLAN based on the source MAC address of the packet. A MAC to VLAN mapping is defined by configuring an entry in the MAC to VLAN table. An entry is specified via a source MAC address and the desired VLAN ID. The MAC to VLAN configurations are shared across all ports of the device (i.e. there is a system-wide table that has MAC address to VLAN ID mappings). When untagged or priority tagged packets arrive at the switch and entries exist in the MAC to VLAN table, the source MAC address of the packet is looked up. If an entry is found the corresponding VLAN ID is assigned to the packet. If the packet is already priority tagged it will maintain this value, otherwise the priority will be set to zero. The assigned VLAN ID is verified against the VLAN table, if the VLAN is valid ingress processing on the packet continues, otherwise the packet is dropped. This implies that the user is allowed to configure a MAC address mapping to a VLAN that has not been created on the system.  To configure a MAC-based VLAN: 1. Select Switching VLAN  Advanced  MAC Based VLAN. 2. Under MAC Address, specify the source MAC address of the host to be bound to a VLAN ID. All untagged traffic that includes this address in the source MAC address field of the Ethernet frame is placed in the associated VLAN. 3. Enter the VLAN ID of the MAC-based VLAN. If an untagged frame received on any port or LAG matches the associated MAC address, it is tagged with this VLAN ID 4. Click Add. 108

MAC-Based VLAN
The MAC-based VLAN feature allows incoming untagged packets to be assigned to a VLAN
based on the source MAC address of the packet.
A MAC to VLAN mapping is defined by configuring an entry in the MAC to VLAN table. An
entry is specified via a source MAC address and the desired VLAN ID. The MAC to VLAN
configurations are shared across all ports of the device (i.e. there is a system-wide table that
has MAC address to VLAN ID mappings).
When untagged or priority tagged packets arrive at the switch and entries exist in the MAC to
VLAN table, the source MAC address of the packet is looked up. If an entry is found the
corresponding VLAN ID is assigned to the packet. If the packet is already priority tagged it
will maintain this value, otherwise the priority will be set to zero. The assigned VLAN ID is
verified against the VLAN table, if the VLAN is valid ingress processing on the packet
continues, otherwise the packet is dropped. This implies that the user is allowed to configure
a MAC address mapping to a VLAN that has not been created on the system.
To configure a MAC-based VLAN:
1.
Select

.
2.
Under MAC Address, specify the source MAC address of the host to be bound to a VLAN
ID.
All untagged traffic that includes this address in the source MAC address field of the
Ethernet frame is placed in the associated VLAN.
3.
Enter the VLAN ID of the MAC-based VLAN.
If an untagged frame received on any port or LAG matches the associated MAC address,
it is tagged with this VLAN ID
