MAC Based VLAN
- Create a group of switched ports.
/interface ethernet set ether7 master-port=ether2
- Enable MAC based VLAN translation on access port.
/interface ethernet switch port set ether7 allow-fdb-based-vlan-translate=yes
- Add MAC-to-VLAN mapping entries in MAC based VLAN table.
/interface ethernet switch mac-based-vlan add src-mac=A4:12:6D:77:94:43 new-customer-vid=200 add src-mac=84:37:62:DF:04:20 new-customer-vid=300 add src-mac=E7:16:34:A1:CD:18 new-customer-vid=400
- Add VLAN 200, VLAN 300 and VLAN 400 tagging on ether2 port to create it as VLAN trunk port.
/interface ethernet switch egress-vlan-tag add tagged-ports=ether2 vlan-id=200 add tagged-ports=ether2 vlan-id=300 add tagged-ports=ether2 vlan-id=400
