Exactly four years ago, I upgraded from #mikrotik #routeros 6.x to 7.x (7.1.2). What a magic moment! So many new features and of course my favorite is #wireguard ! Others are #macsec and #vxlan… Forgot to mention #mvrp ;-)

πŸ” MACsec: Layer 2 Encryption for Modern Networks
When IPsec or TLS are too high in the stack, MACsec (IEEE 802.1AE) offers an efficient way to secure Ethernet frames at Layer 2β€”with low latency and line-rate performance.

In this post:
β€’ How MACsec works (SCI, SAK, EAPoL)
β€’ Trust model: Secure vs. insecure ports
β€’ Hardware dependencies & deployment scope
β€’ Typical use cases in data centers and enterprise access

Building and testing #mikrotik network setup with #gsn3 is awesome! Had a problem getting #macsec running on my physical devices, so I built a test setup with gns3. My mistake was, that I had to remove the physical ports from the bridges *before* using them for macsec! No more β€žinternal errorβ€œ! \o/

If you wonder for hours why the #macsec interfaces on your #mikrotik devices do not forward any reasonable traffic (such as dhcp-requests…) set the MTU of both to 1500 ! πŸ€¦β€β™‚οΈ
