LACP and DHCP Snooping Question

RouterOS Beginner Basics
1

Hoi RouterOS Folks

This, maybe, sounds like a stupid question… i have a scenario with a CRS3xx switch and two link SFP+ LACP Bonding as uplink interfaces to another CRS3xx switch (core) where the trusted DHCP server ist located. Now i read that DHCP snooping is not possible with hardware offloading LACP bonding active? Does this only affect DHCP bonding with option 82 enabled?
I have a lab env here with DHCP snooping (w/o option 82) enabled and LACP bonding as uplink (trusted), with different CRS3xx switches as access and core and it seems like it works?!

Im a bit confused what scenarios this “DHCP snooping does not work with HW offloaded LACP bondings” are affected… maybe you can enlighten me :slight_smile:

Firmware is v7.14.3 on every switch.

Best Greetings

From my understanding it should behave like a trusted port, just because DHCP Snooping is not “working” on this bond.

Found something in the documentation:

“Starting from RouterOS v7.17, DHCP snooping is supported with hardware offloading bonding interfaces.”

Once 7.17 is released, we should have the support for this on some devices.
