HP Switch Port Question

Last Modified: 2018-04-12
Yesterday we had an uplink from our hp procurve network to our extreme switch network go haywire.   Basically what happened is that here was a bad switch on the extreme network that brought the whole extreme network down and that traversed over to our hp procurve network and started to bring that down.

Is there any sort or port protection I can enable on this uplink port (other than spanning-tree) to disable this port in the event of a future occurance.   What happened was that the extreme network lan was saying that every address was a duplicate address on the HP side when that was clearly not the case.

just looking for ideas...

STP is your friend there.  I don't think that's a hardware issue; it sounds like a network loop, which STP is supposed to protect from.  Configured correctly, STP would have sorted it.

Just in case... Craig is referring to Spanning Tree Protocol.
Log in to your switch and check to see if it's enabled/disabled.

I don't agree that it's a hardware problem.  Quite often, swapping hardware just masks an issue.  STP, when managed properly, will alleviate these issues.

We replaced the older switch and moved one.

That screams STP loop to me.
