Crappy LACP support (802.3ad) for the High-End Switches like CRS226-24G-2S with QCA8519 chipsets

Mon Feb 08, 2016 9:52 pm

I would like to use a such basic feature as LACP on my $300 switch. The feature is available in the Mikrotik OS v6.34.1 but the switch chip design using the QCA8519 is another story. I'm confused with the switch module architecture. Somebody got it working?

I'm Cisco CCNP Certified so I know what I'm doing at the other end (Cisco 3560) and the LACP port-channel doesn't go up.

Thanks for any help!

As far as I know, the only way to do LACP with CRS is using a bonding interface, which unfortunately, is CPU-forwarded, so you won't get nearly the performance out of this that you would with hardware-forwarded sessions. As one long-term Cisco guy to another - I agree, the switch menu seems overly-complicated.

Yeah, unfortunately, 802.3ad compliant LACP is not supported in hardware yet, despite the community railing at MT for A WHILE to get this done. You can use bonding (which won't give you the throughput you want because the CPU in the CRS is too weak), or you might try trunking (/interface ethernet switch trunk). It's under the switch menu, so one would think it's implemented in the switch chip, but even on the MT wiki, they state that it is NOT 802.3ad compliant (http://wiki.mikrotik.com/wiki/Manual:CR ... s#Trunking). I haven't used this feature, so I don't know whether it's really hardware-based or CPU, or whether it's compatible with Cisco port-channel.

Do you think it's ever coming? How fast is Mikrotik to usually fix stuff like this?
