LACP mode removed from trunk(4) https://www.undeadly.org/cgi?action=article;sid=20260113070814 #openbsd #networking #trunk #lacp #development #current

🧵 3/n #LACP is kinda useless, unless redundancy is your goal.

My NAS and PC are now connected via 2x 2.5G bond0 in round-robin mode. It's mostly working as intended, almost double the bandwidth of a single link.

Edit: those are direct cable connections without switch. If I need more ports, I'll add USB dongles to br0.

And yes, of course I can put bond0 in br0, but "netplan apply" locked up the whole NAS - had to power cycle it. Valid config though, boots just fine.

Facing network congestion in your industrial operations?

Standard switches can’t efficiently manage multiple high-bandwidth links.
Versitron LACP Switch for Industrial Load Balancing aggregates multiple connections, maximizing throughput and ensuring reliable, uninterrupted communication.

How do you handle heavy network traffic in your industrial setup?

Строим отказоустойчивую сеть на PacketTracer (HSRP,LACP)

Привет, дорогие коллеги! Сегодня мы разберем, как построить надежную и отказоустойчивую сеть с использованием ключевых сетевых технологий, таких как HSRP, LACP и Port-Channel. Мы рассмотрим теоретическую топологию, которую можно частично смоделировать в сетевом симуляторе, например, в Packet Tracer. В этом руководстве мы разберём: HSRP : Как настроить автоматическое переключение на резервный маршрутизатор, чтобы доступ к интернету не прерывался. EtherChannel : Как объединить несколько сетевых кабелей в один, чтобы увеличить скорость и обеспечить резервирование. VSS и StackWise : Как объединить коммутаторы в единое целое для простого управления и максимальной надёжности. Мы подробно рассмотрим реальные примеры конфигураций и объясним, как работают эти технологии на практике. Если вы хотите, чтобы ваша сеть работала как часы, эта статья — ваш путеводитель.

LACP под лупой Wireshark

Привет Habr, всем максимально доброго дня!!! После первой статьи прошло... чуть больше времени, чем рассчитывал, и вот решил продолжить тему медленных протоколов: сегодня LACP. Хотел рассмотреть его подробно, но получилось как-то уж совсем подробно, так что, как это говорилось в далеком 2005м, извените за многабукаф. С самого начала, давайте вспомним самую важную картинку из прошлой статьи, а точнее - схему работы агрегированного канала.

#LACP => J'AI ENVIE DE CREVER

100% unnecessary to run at home but I'm trying to keep my nerd cred up. Been doing so much Threat Intel lately that I wanted to do something Network-y.

@sodiboo instead if using proprietary SaaS like Tailscale I can recommend using #pfSense and other Networking-focussed #distros to manage your #WireGiard Setup where you can easily deploy & maange configs for clients and the clients themselves...

• Besides that you are correct: Similar to #LAGG / #LACP-#Bonding and #VLANs, WireGuard is a virtual interdace that is treated natively, unlike #tun / #tap interfaces for like #OpenVPN...

Dear #followerpower,

does #bonding in #Linux with balance-alb work with direct attached cables between two servers or is a switch needed (although it doesn't need to support balance-alb like #lacp)

3 servers, each server has 2 directly connected ports to each other server in a bond, and bond0 and bond1 on each server is connected to a vmbr1 interface.

Basically this is working, but with iperf I didn't see any increase in bandwidth.

If you are unlucky like me and you have 2FA on and then you swap disks, suddenly you are unable to use 2FA. So the solution is to do a Mode 1 reset.

That means you find the reset at the back of the NAS and then press it for four seconds, it will beep. And then reset the user accounts and also the network.

The user account will be admin with no password, but the other trick is that a network reset will mean that if you had a link aggregation setup, the thing will disappear from your network. You need to move one of the Ethernet cables to a non-LACP port to see it again. This confused me because it looks like it is there but doesn't respond.

Later when you get LACP running you go to Control Panel > Network and set it up. You bond two together and then you can get double the bandwidth (technically each client is limited to a single Ethernet bandwidth like 1Gbe, but the second one gets the other side, so good for more clients). 10Gbe is nice but you typically don't have that for every client. It's too expensive.

I am trying to bond a pci nic and a usb nic in #alma 8

(don't ask why...)

I'm seeing messages that
>>> ALB mode requires that the base driver support setting the hw address also when the network device's interface is open

which makes me think the USB nic isn't compatible.

I can't do #lacp since I don't control the switch (don't ask why...)

Would 'teaming' work? I think that's a different thing altogether? Or wait for my nic that's on order...

Mein #Router ist jetzt endlich mit 2x 10GbE an mein Netzwerk angebunden. Das 1GbE-Bottleneck ist damit nun endlich Geschichte. High speed routing: now! :)

Mais pourquoi c'est toujours la misère pour configurer un #LACP #802.3ad 😱

and we are *done*

work just did a major migration from #mstp spanning tree, to a #EVPN #backbone spine/leaf configuration, where the leafs are connected with multi-chassis #lacp.

~12s outage per switch as we converted from old-world to new-world, including updating the mac-tables for all switches in our network.

6 months of preparation. 1 month of *serious* prep. 1 day move a few non-critical systems, and let them percolate. Then, 7 days of swingshift to move everything else..
