Fast Path not being used

RouterOS General
1

Hi

I have a Mikrotik CRS125-24G-1S-2HnD operating as a router for a cable modem with internet access. I have a computer connected to a port, and a POE switch connected to a few CCTV IP cameras. The cameras send video data to the server. When I look at the traffic stats for the ports, they are not using Fast Path.

How/can I make this traffic use Fast Path and save CPU?

Connection Tracking is on Auto, and IGMP Snooping is off. Fast Forward is On for the bridge-local.

Thanks

Most probably you are using the switch so there is no cpu involved in processing of internal traffic at all. At least you should, in any other case.

Thanks, so using the Switching chip is different from Fast Path?

4

Absolutely. It is hw switching in separate chip against sw bridging by cpu.

Thank you.

Are there any disadvantages to using Fast Forward (which I assume is the same as Fast Path)?

7

It is not the same. See the manual.
