Re: SolidMount experience

Stainless on Stainless have a "galling https://en.wikipedia.org/wiki/Galling" problem.
Greasing the nuts and limiting the applied torque tends to alleviate the problem.
There are "anti-seize" products designed for aluminum, that will also greatly help on stainless.

CRS317- Bonding Offload [SOLVED]

Hi, i was under the impression that Bondings using the CRS317 should be offloaded from the CPU, but that's not what i'm seeing (networking eats 50% of CPU, and Bandwidth is bottlenecked.)

I'm using Bonding-XOR with 3+4 hashing.


What modes are supported in RouterOS 6.44.3 and are HW-Offloaded?

try connecting your laptop to the port labeled as "8-BOOT"
