Buffalo BS-XP20 BS-XP2012 Unmanaged Switch LACP 802.3ad support
« on: September 13, 2017, 03:35:23 pm »
I would like to confirm that the BS-XP20 BS-XP2012 switch can utilize the 802.3ad protocol.  Looking at the manual, it doesn't mention it but if I had to guess I would say it's under the "Port Trunking" section.  Unfortunately the manual doesn't give the possible modes and only says "Trunk Mode - Select a trunk mode".  Thank you for any assistance.

That switch does not support LACP.

Thank you for the info!
Does the switch support any type of link aggregation?

The only port trunk mode is "Manual" which is essentially failover.

You da man Texturle!

I should have thought of this and asked all my questions in one post but, does the similar model (BS-MP2012) support any kind of Link aggregation?

edit: any plans for future support?

The BS-MP switches behave the same way, no link aggregation support. I do not know at this time if either this switch or a future switch will have this capability. This switch was designed as a low cost entry into 10GbE networking. The primary feature of the MP series is that they support IEEE802.3bz which allows them to negotiate link speeds of 5Gb or 2.5Gb if 10Gb can't be achieved due to cabling or device compatibility. There are currently at least a few motherboards available that will run 5Gb but not 10Gb, so this switch will work with those just fine. The XP series is only capable of doing either 10Gb or 1Gb. In the event that someone wants to try to run 10Gb over CAT5 it will work but not for longer distances. At cable runs over about 30 meters 10Gb over CAT5 becomes impossible but if the switch and the device support 802.3bz they can negotiate a 5Gb connection and not have to drop all the way down to 1Gb.
