SGE2000 G5 VLAN causes internet speed degradation

[Andrea_Lello]

Hi,

I have a problem with a test network configuration i'm trying to set up.

I have an SGE2000 G5 switch for LAN traffic, and i have "reserved" 3 ports with a VLAN to obtain two separate internet lines with two different public IPs from my ISP internet cable.

Now what i've tried to do is connecting the ISP cable to the port1 of the VLAN, and i've connected the other 2 ports to my routers.

The problem is that when doing this, port1 switches to half-duplex mode and the result is a huge performance degradation (0.28Mb DL instead of 16Mb approx.).

I'm stuck at this point and i have no clue why this is happening. Any idea?

Thanks in advance.

Hi,

I'm facing a similar issue, any idea about how to solve? It's possibile, to use a LAN switch to switch also internet signal with VLANs?

Thanks in advance for any help
