I’ve received a brand new CRS317-1G-16S+ and it was very slow. So I decided to upgrade and it bricked.
This problem was solved with netinstall by serial, because it won’t respond to reset button.
Now I’m testing with bandwidth and CPU load dont get higher than 50% as shown below:
The test is singel threaded and only uses one core which is 100 % load which is 50 % in total as there are 2 cores.
You should test the throughput of the router/switch from a machine attached to the router/switch.
