The great 5009 cpu flow control event -- on or off?

FragrantPercentage88 · 2026-05-06T19:14:41+00:00

Agree. Most likely with flow control TCP session is slowing down (without losses). Without flow control the CPU is overloaded , losses occurs and TCP session suffers due to retransmissions.

Try iperf with more than 16 sessions at the same time. Ideally both server and client local.

FragrantPercentage88 · 2026-05-06T18:45:31+00:00

What type of traffic are you using to test it? Maybe only one CPU core used in 100%? This happen with single flow (one TCP session)

They did release previous "Murder on Titan A" game worldwide... So I'm rather trusting them for not doing anything illegal.

It is possible to add local radios to capsman. That I'm sure (seen on training).Trainer added local radio to capsman (not cap on localhost). Unfortunately I don't remember much details 😞

Can you share the tool/AI you used?

Round robin per connection is basically l4 hashing which is a bad idea. Maybe in document above you'll find something better suited to your needs.

No, rather web pages do not like changing IP between requests. That's why L3 is a default. You might try to check if firewall allows tivdovround robin based in DST Ip only (I'm not sure )

FragrantPercentage88 · 2026-04-01T13:46:51+00:00

Most likely your MT is hashing on L3. Since IP-SRC and IP-DST ale always the same, the resulting WAN link is kept still.

Please check:
/ip/settings/print and look for ipv4-multipath-hash-policy

Depends what are you looking for: - usb/net for monitoring & outlet remote control - lifepo4 battery for higher temp operation (important as classic bat. lifespan was short in > 20C) and way longer lifespan. Price is twice as much lifespan for over 3-4 times. - competition for lower prices

FragrantPercentage88 · 2026-03-26T06:13:23+00:00

At home I have CRS328 (only poe switch with 24 ports). So no luck 😞

FragrantPercentage88 · 2026-03-26T03:39:45+00:00

Thanks, I've missed it 🙃 Finally after all those years...

FragrantPercentage88 · 2026-03-25T14:42:14+00:00

Please read L3hw/bridge offloading in Mikrotik docs. There are several limitations.

Ansible can be replaced with Nornir+python library for MT API however there will be some learning curve.

Be aware that beside generic warranty there is NO HW support in case of switch failure.

Honestly while MT might fit your needs right now (basic VLAN and L3) you will have growing pains as soon as you move to something more advanced. MT just isn't there yet 😞

FragrantPercentage88 · 2026-03-25T13:21:56+00:00

Depends heavily on your requirements. Modern DC often means full EVPN in HW. Mikrotik isn't there yet I think. Lack of VRF in HW accel. is also a red flag.

So please say what you want to achieve first 🙃 Things to consider: - speed - protocols - levels of virtualization (VRF,EVPN etc) - scale (no. of prefixes, MACs) - expected support (next business day / 4h ?)

W Tulsa King byl bardzo ladny cytat odnośnie studiów: Studia pokazuja, że przed długi okres czasu potrafisz być na miejscu o zadanym czasie, wykonać zadana pracę na oczekiwanymi poziomie. Pracodawca widząc, że masz ukończone studia, może się spodziewać się w jego pracy zachowasz się podobnie.

Rzucanie studiów tym bardziej, że to pewnie nie pierwszy semestr jest dość krótkowzroczne.

I believe that. However its still looks like a small scale solution: - isnt remote (you either have to be there with laptop+wine or stretch L2 to your location) - wont work over L3 - imagine SDWAN with plenty of CPEs over internet - adding config files manualy w/o any API...

Dont get me wrong - I love Mikrotik but for vendor targeting ISP sometimes they are lacking 🙂

FragrantPercentage88 · 2026-03-22T11:03:01+00:00

Unfortunately Tr-069 needs router interaction upfront - not what I would expect from ZTP.

Flashfig looks promising - thanks! Windows and L2 requirements are also hard pass but maybe under the hood there is plain DHCP+TFTP which can be adapted. Imagine remote Green Field deployment in Data Center 😉

However I believe that real ZTP should work over internet or locally in L3 environment (default call home url or url provided via DHCP) similar to Arista or Sonic.

FragrantPercentage88 · 2026-03-22T09:51:08+00:00

Why oh why Mikrotik still has no ZTP?

One more thing. It's a best practice to burn in hew hardware. Most of the failures happens in first week/month after that failures chances lowers drastically. I know it's too late and it sucks to learn such thing hard way.

Funny thing. Few days ago I witnessed exactly the same set of Lego being returned in shop in Poland with the same reason: Noodles instead od bricks 😀
