I have a large set of GS108TV2 units--my goal is to set up a network which is comprised of several loops for redundancy/fault tolerance.

I have a minimal 3 switch loop configured, with RSTP enabled on two ports on each switch. I have my bridge max age set to 6, and my bridge forward delay set to 4, which are the minimum values allowed. Hello time is fixed at 2 seconds. The switches respond to a cable being removed from a socket, but it takes too long.

I cannot get the switch to respond to a loss of connection on one of the redundant ports in less than 20 seconds.

Is there any way to configure these switches to respond faster than 20 seconds? That is unacceptable for my application.

thanks in advance for any help
