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.
•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.
Workflow
To define a MAC-based VLAN group:
1. Assign a MAC address to a VLAN group ID (using the MAC-Based Groups
page).
2. For each required interface:
a. Assign the VLAN group to a VLAN (using Mac-Based Groups to VLAN page).
The interfaces must be in General mode.
b. If the interface does not belong to the VLAN, manually assign it to the VLAN
using the Port to VLAN page.
