Mikrotik RouterOS 6.41 changes

Been a little busy the past week, but did notice Mikrotik RouterOS 6.41 released on 22nd Dec 2017.

It has some significant changes that I wanted to highlight from the changelog and quickly show the changes in the winbox interface.

!) bridge – implemented software based vlan-aware bridges;

!) switch – “master-port” conversion into a bridge with hardware offload “hw” option;

!) detnet – implemented “/interface detect-internet” feature;

The switch changes is the one that got my interest, as this is the one that I have known and used since I first started to use Mikrotik hardware. So now I have to get my head around the fact it has changed.

routeros-pre-6.41-interface
routeros-post-6.41-interface

You can see from the images above that Master Port is no longer used and/or available under your interfaces to group interfaces together as switched ports. This is now done differently.

Upgraded one of my routers and I think I understand how this change impacts future configurations and setup process.

Intel 7th Generation Desktop vs Laptop CPU sample

Intel Core i3 7100 (Desktop CPU)

distributed.net RC5-72 workload sample – 80 packets.

[Dec 27 09:41:10 UTC] RC5-72: Summary: 80 packets (80.00 stats units)
                      0.00:37:47.78 - [149.06 Mkeys/s]

Intel Core i7 7500U (Laptop CPU)

distributed.net RC5-72 workload sample – 85 packets.

[Dec 27 11:04:28 UTC] RC5-72: Summary: 85 packets (85.00 stats units)
                      0.00:46:22.95 - [128.69 Mkeys/s]

Surprised that the i3 Desktop has the slightly better throughput on this workload. I somewhat expected that the i7 to win. The interesting thing to note though is that of course the i7 laptop CPU would be using way less power, thus generating much less heat. It makes me wonder though… how would an i3 laptop CPU perform in this test when compared to the i7 laptop CPU. Unfortunately I do not have one to test.

New Magazine Subscription

I always get a magazine subscription every year. But honestly haven’t been enjoying the magazine I would typically get in Australia. Linux Format recently got my interest, and they had some specials over the Christmas period which has help to sway me over. Tonight I noticed they had even further discounts – another 20% off. So I jumped on the bandwagon and signed up for a 12 month digital only subscription.

New Tablet – Samsung Galaxy Tab A

Merry Christmas everyone.

Today I got a new tablet. My wife purchased me a Samsung Galaxy Tab A (2017) model. This will enable me to use it in situations where a laptop doesn’t really allow. The tablet is very handy when on public transport and relaxing on a cruise ship. Will give me a chance to load it with content and consume as needed.
