Graphs

My RB750 doesn’t show the real trafics. I use it as a switcht with VPN server.
Interface Setting:

NAME MTU MAC-ADDRESS ARP MASTER-PORT SWITCH

0 X ether1-… 1500 00:0C:42:5A:95:21 proxy-arp
1 R ether2-… 1500 00:0C:42:5A:95:22 enabled none 0
2 RS ether3-… 1500 00:0C:42:5A:95:23 enabled ether2-local-… 0
3 RS ether4-… 1500 00:0C:42:5A:95:24 enabled ether2-local-… 0
4 S ether5-… 1500 00:0C:42:5A:95:25 enabled ether2-local-… 0
If I change master ports to “none” - all graphs show the correct numbers, but without switch funcion.
What is the correct setting?
