26.7.2 Connectivity and MAC addressing between devices

When a MAC VLAN is configured on multiple switches, we recommend that you use a trunk port for connections between the switches. VLAN judgment for frames received on trunk ports is performed by VLAN tags. This allows communication by MAC VLAN, even when no source MAC address is set for a VLAN. For details about how to connect devices using trunk ports, see "Diagram 26-8 MAC VLAN Configuration Examples."

When a MAC port is used to connect switches, all MAC addresses belonging to the VLAN need to be set on all switches. If a router exists, register the MAC address of the router.

The following figure shows switches connected by MAC port.
