Link aggregation setup with TP-Link TL-SG3210

[killer14]

Hi, I am setting up link aggregation with TP-Link TL-SG3210. I know this switch is not supported, but the only two who are supported are "out of date"

My set up:
router : asus N66u one utp cable to TP-Link TL-SG3210
NAS DS412+ connected with 2 utp cables in aggregation mode, 2 cables to another TP-Link TL-SG3210 switch, two cables in to my pc with two broadcom gigabit cards in teaming mode (2 gbs connection)

Both switches created 2x2 LAG groups (working according to the switches).

Perfomance start with 80-85 mb/s and drops to 45 mb/s. Is not really stable.
DS412+ in raid 10 mode with 4 x 3 tb 7k3000 HD's.

when I don't use LAG performance is about 65-85 mb/s....
My "old" NAS QNAP TS-459 PRO+ had in this setup 80-105 mb/s


I checked all the cables, switches etc... everythings looks ok. I can see the LAG is working, because of the groups blinking at the same time and speed on the switches....



Any suggestions? Remarks ?
Please help me to achieve >150 mb/s....

Hello, I see that you listed the ASUS N66u as your router. Is this the new ASUS "black" Knight router? I only ask because if you go to the ASUS forum, portforwarding does not work. If you somehow have it working, please let me know how. I had a CISCO E3200 and everything worked fine, but this brand new (fast) router won't do port forwarding.

Killer 14, could you please tell me what you did to get this to work? I tried running the wizard, but it says it can't find my router model. I would really appreciate if you could tell me how you got the forwarding to work on the router.

I'm setting up a LACP with a DS 412+ and a TP-LINK TL-SG3216. So pretty similar. For me the main reason is parallel speed for multiple users, so the computers have a single NIC.

Apart from that, I also get slower speed after I've set up the LACP 802.3ad connection. About 80MB up/ 100MB down without LACP and 46MB up/ 55MB down with LACP activated.

ah ok I am now trying the HP Procurve switch.. I will let you know!

[Jojakim]

Great, would like to hear your findings!

Nice thread, I'm also researching going lacp on my 1812+

Are you guys using jumbo frames? Try with and without maybe?

[killer14]

yes did some jumbo frame testing but still no luck in getting good speed, just changes my volume to hybrid raid same speed start doubting my broadcom network cards....perhaps I shoud try intels....

[sjacob]

I can get a good deal on a TL-SG3216

Is it a good product? (I have no experience with tp-link)

[killer14]

yes good stuff but bought pro curves because those should work...

[sjacob]

Also looking for a fanless model personally

[killer14]

both tp-link and procurve are fanless

[sjacob]

What about price?

Which procurve model are you suggesting?

16 port rackmount as well?

[killer14]

HP Procurve V1810-8G

had them cheap at hardware.com
about 70 euro each bought 2

[killer14]

switches setup HP procurves, performance still not enough..same as above...
Will try an intel pro dual gbit card to see what happens....
