VLAN Groups
VLAN groups are used for load balancing of traffic on a Layer 2 network.
Packets are assigned a VLAN according to various classifications that have been
configured (such as VLAN groups).
If several classifications schemes are defined, packets are assigned to a VLAN in
the following order:
TAG : If the packet is tagged, the VLAN is taken from the tag.
MAC-Based VLAN: If a MAC-based VLAN has been defined, the VLAN is
taken from the source MAC-to-VLAN mapping of the ingress interface.
Protocol-Based VLAN: If a protocol-based VLAN has been defined, the
VLAN is taken from the (Ethernet type) protocol-to-VLAN mapping of the
ingress interface.
PVID: VLAN is taken from the port default VLAN ID.

MAC-based Groups

MAC-based VLAN classification enable packets to be classified according to their
source MAC address. You can then define MAC-to-VLAN mapping per interface.
You can define several MAC-based VLAN groups, which each group containing
different MAC addresses.
These MAC-based groups can be assigned to specific ports/LAGs. MAC-based
VLAN groups cannot contain overlapping ranges of MAC addresses on the same
port.
The following table describes the availability of MAC-based VLAN groups in
various SKUs:
