RB750G switch and monitoring

Hi!

I have a question regarding the switch chip installed in the 750G routerboard.
It's a Atheros 8316 chip installed.

To activate the switch function I have made on this 5 port RB ether1 the master port for the rest.

 interface ethernet print detail 
Flags: X - disabled, R - running, S - slave 
 0 R  name="ether1" mtu=1500 l2mtu=1524 mac-address=00:0C:42:71:B9:B8 
      arp=enabled auto-negotiation=yes full-duplex=yes speed=100Mbps 
      master-port=none bandwidth=unlimited/unlimited switch=switch1 

 1 RS name="ether2" mtu=1500 l2mtu=1524 mac-address=00:0C:42:71:B9:B9 
      arp=enabled auto-negotiation=yes full-duplex=yes speed=1Gbps 
      master-port=ether1 bandwidth=unlimited/unlimited switch=switch1 

 2  S name="ether3" mtu=1500 l2mtu=1524 mac-address=00:0C:42:71:B9:BA 
      arp=enabled auto-negotiation=yes full-duplex=yes speed=1Gbps 
      master-port=ether1 bandwidth=unlimited/unlimited switch=switch1 

 3  S name="ether4" mtu=1500 l2mtu=1524 mac-address=00:0C:42:71:B9:BB 
      arp=enabled auto-negotiation=yes full-duplex=yes speed=1Gbps 
      master-port=ether1 bandwidth=unlimited/unlimited switch=switch1 

 4  S name="ether5" mtu=1500 l2mtu=1524 mac-address=00:0C:42:71:B9:BC 
      arp=enabled auto-negotiation=yes full-duplex=yes speed=1Gbps 
      master-port=ether1 bandwidth=unlimited/unlimited switch=switch1

But unfortunatelly I am not able to monitor the traffic on each port individually.
There should be a traffic also on the ether2 port, as I'm pingig the device attached to it.
Se the attachment.

Please advise me how can I monitor the traffic on each port individually.
Thank you!

Best regards

In switch mode, you can't monitor slave interfaces, only master, as far as i know. If you want to monitor each interface put RB in bridge mode.

You can get stats from switch chip itself:

/interface ethernet print interval=1s stats where name="ether1"

In switch mode, you can't monitor slave interfaces, only master, as far as i know. If you want to monitor each interface put RB in bridge mode.

I know that is possible to put it in to bridge mode, but is more hw demanding that the switch chip.
Tried both ways. bridge mode was about 20Mb/s slower then the switch chip.

@kirshteins
is possible the monitooring trough dude ?

Thanks for the reply!
