Bridge Fast Path Packets not counting

RouterOS Beginner Basics

I am using 4 Mikrotik Devices and on 3 of them Bridge Fast Path Packets are counting.
On the 4th Device (hAP ac²) I have exact the same configuration like the others but Fast Path seems not working.
I also took care about Bridge handler but I cann’t find the reason.


/interface bridge
add admin-mac=CC:2D:E0:XX:XX:XX auto-mac=no igmp-snooping=yes name=bridge1
/interface bridge port
add bridge=bridge1 interface=ether5
add bridge=bridge1 interface=ether4
add bridge=bridge1 interface=ether3
add bridge=bridge1 interface=ether2
add bridge=bridge1 interface=ether1
add bridge=bridge1 interface=2G
add bridge=bridge1 interface=5G
/interface bridge vlan
add bridge=bridge1 tagged=ether1,bridge1 vlan-ids=2,3,4

Any Idea?

May sound stupid but post a “working” config and then your config for the device not working for us to compare.
Most likely a simple setting in bridge like “use firewall” not checked.

Here a working one:

/interface bridge
add admin-mac=CC:2D:E0:XX:XX:XX auto-mac=no igmp-snooping=yes name=bridge1
/interface bridge port
add bridge=bridge1 interface=2G
add bridge=bridge1 interface=5G
add bridge=bridge1 interface=ether1
add bridge=bridge1 interface=ether2
add bridge=bridge1 interface=ether3
add bridge=bridge1 interface=ether4
add bridge=bridge1 interface=ether5
/interface bridge vlan
add bridge=bridge1 tagged=ether5,bridge1 vlan-ids=3,2,4

Strange, I found out, if I disable fast forward then fast path packets are counting.

/interface bridge
add admin-mac=CC:2D:E0:XX:XX:XX auto-mac=no fast-forward=no igmp-snooping=yes name=bridge1
/interface bridge port
add bridge=bridge1 interface=ether5
add bridge=bridge1 interface=ether4
add bridge=bridge1 interface=ether3
add bridge=bridge1 interface=ether2
add bridge=bridge1 interface=ether1
add bridge=bridge1 interface=2G
add bridge=bridge1 interface=5G
/interface bridge vlan
add bridge=bridge1 tagged=ether1,bridge1 vlan-ids=2,3,4

I suspect this is hardware related. I see the same behavior on my PTP links that are DynaDishes or QRT-5’s, but on my LHG 5ac links, the fast path packets count whether fast forward is enabled or not.

In your original post, you said your 4th device that wasn’t counting was an hAP ac2, but you never said what the other three were.
