Spanning Tree and Loopback Detection for Dummies

[LeightonJames]

Following a number of issues at a particular site I have finally configured the 2 switches on site with their correct IP's and passwords

 

I was looking into loopback detection and spanning tree but have NEVER configured either option as our previous method of imaging often caused the switches to incorrectly disable ports rendering the imaging session useless.

 

This leads me to this morning.

 

Both switches are D-Link DGS-1210-48, I have enabled Loopback Detection on both on all ports, is this enough to prevent accidental double uplinks from bringing down the network or do I need Spanning Tree too?

From experience with the same switches, loopback detection on those gives you the same symptoms as having a loopback unless you're on the most recent firmware so please double check you're on the latest version. That should be enough without spanning tree.

Will check now, thanks for the warning
