Hello all,
I am trying to get a 10gb link working between my upstairs office switch (CRS305) and my basement server rack switch (CRS317) but I’m having trouble with high cpu usage on both switches and low bandwidth:
Both switches are running RouterOS version 7.8 and I’ll post the config exports below. I thought I followed the guide for hardware offloading correctly, but maybe I’ve made a mistake in my config somewhere? Any help would be greatly appreciated.
