Configure redundant SFP links
We recently purchase D-Link DGS 1210-48 switches. Would like to configure them so that the SFP fiber links work in a redundant fashion, if one goes down the system will switch over. I have looked through the manual, but could not find what I was looking for. Can someone tell the command(s) that would enable this?
I can't help you with the commands but why not setup them up in a ring topology and just have the spanning tree protocol handle it?

I am rather new to configuring switches, can you point to reading that explains what you are speaking of? Thank you for your quick response.

A ring tolopogy is that you connect the 1st switch with the 2nd and the 2nd with 3rd and the 3rd with the 1st switch. Thus creating a ring.

Basically the STP is a database of MAC addresses hosted on the switches. And, very simply, it tells network packets where to go. So that you don't get to much broadcast traffic. Most GUI based switches have it enabled by default. If you only have 1 VLAN I suggest using Rapid-Spanning Tree.

If you want to create redundant connections with a switch, you would need to create a LAG on the switch. Link Aggregation allows multiple links to be bonded together.
