11.3.11 Managing MAC-based VLAN
11.3.11.1 MAC-based VLAN Configuration Page
MAC-based VLAN feature allows incoming untagged packets to be assigned to a VLAN and thus
classify traffic 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.
Selection Criteria
MAC Address - Selects the MAC Address bound to a VLAN. To add another MAC VLAN entry,
select "Add" option.
Configurable Data
MAC Address - Valid MAC Address which is to be bound to a VLAN ID. This field is configurable
only when a MAC-based VLAN is created.
VLAN ID - VLAN ID can be any number in the range of (1 to 4093).
Priority - Priority can be any number in the range of (0 to 7).
Command Buttons
Submit - Update the switch with the values on this screen. If you want the switch to retain the new
values across a power cycle, you must perform a save.
