Cisco NAS using Link Aggregation is only copying at 120 Kb/s why?

Bought a Cisco "NSS 324 Smart Storage" NAS, and installed it.

I connect it to a SLM2048 Cisco smart switch, and followed (to the best of my knowledge) the very simple step in setting up a LAG.

I included the images of the settings, hope that there is something wrong there that would explain the slow copy speeds.

How are the switchports configured. If they are not setup as a port Channel or a possible trunk you may be running into mac flapping and the switch does not know which one to use since it is constantly seeing the same mac show up on two different ports.  Generally you would set them up as a port channel if you want faster throughput and as a trunk if you want redundancy.  The LAG should assign the pair a single MAC and if it flaps every time the table is update it will create more overhead.

It may also be negotiation you are telling it to use max capacity but you have the switch it looks like set to static 1000 full.  Make sure the speed and duplex matches on all devices.

how do I check your first issue?

As you can see on my included image, not that much I can really change that would make much difference. I will try to change the setting, not holding my breath though.

I changed from round robin to the XO setting as pictured, this bumped the speed up a little.

Shouldn't this be pretty simple?

It should be but one thing to try maybe would be to turn off all of the LAG settings and use a single connection and see if the speed increases.  Since you are getting nowhere near what a single link should run even.  If you do that then we can try to build the LAG from the ground up.

The first part you are looking for something in the swtich that pertain to channel group I usually use IOS and am not sure where it is in that switch type.
