HP Switch Port Question

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...

We had a similar situation where an older HP switch appeared to have caused one of two newer HP switches to stop working correctly (so no connection for some people; good connection for other people).

We replaced the older switch and moved one.

We had to replace an older HP switch at another client as well (more limited scope).

I do not think there is much you can do about the hardware problems. We are alert to replacing older switches.

Agree with John. Other than replace the older switches the best you can do is update the software image.
If the software update doesn't improve the situation -- then replace.

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.
