RB750UP does not whow any traffic

Hi

RB750UP running 5.21

I have set 3, 4, 5 to master switch 2.

Running a rb1000 on port 4 and 5. I can ping from rb1000 to rb1000 via 750up.

But the interfaces in the rb750up does not show any traffic ?

Switched traffic does not go to CPU so it is not accounted. It is possible to count traffic only if it reaches CPU.

so its should be 0 bps on the interfaces? not even on the master interface?

You can still see some stats on switch chip ports if you run following commands:
/interface ethernet print stats
/interface ethernet switch port print stats


driver-tx/rx bytes/packets are not counted for switched ports. These values are also ones used to show stats in winbox.

For example ether3 is slave port. As you can see it has no driver stats, but you can still see total received sent byte count and number of packets.
