I have a SG 200-26. Port 1 goes to Internet. Port 2 to a Synology NAS. Port 3 to a 'small' gigabit hub with a computer and a media player connected. All gigabit connections. The media player uses NFS to access a share on the NAS. How do I configure the SG200 to get max throughput?
Reason is: before I used the SG200 I used a standard hub. THroughput was perfect, HD movies played seamless. With the SG200, performance is significantly less. HD movies are not playable.
I tried switching QoS on, ports 2 and 3 to level 7, and off. Did not solve the prob.
You may enable a basic QoS per port which will classify traffic off the DSCP map, this is true and may be helpful. You can try to set manual port negotiation. You may want to check the port status to see if it is negotiation 1000, 100 or 10 and if it is full or half duplex.
Try setting the port to 100 full or 1000 full.
Please mark answered for helpful posts
Sorry, but this does not solve the prob either. Have the port on 1000 full, QoS for both relevant port to 4. I also tried Jumb o Frames on, but I guess that only makes sense if also NAS and other components are in Jumbo frame, are they? As that is where the problem is, the media player I cannot set to jumbo. I dont understand why the switch is causing this trouble, Could it be the cooperation with the gigabit-hub at the tv-set that does not like the SG200?
