Cisco 3524 drops all ports

[vasquezj]

We are using Ciscos 3524 XL switches running 12.0(5.4)WC(1) IOS. All of the switches in our network lost communication with all of our devices. there was no power loss. Has anyone experienced this problem? Any help would be appreciated.

Thanks

This also is a case where I would at least check out what was going on with spanning tree during the outage period. I have seen this several times. If nodes on a local area network inexplicably lose connectivity, and it impacts everyone, then spanning tree problems should be considered. It could be as simple as some network event caused a request for spanning tree topology change to be issued, etc. In this case, it will still take as long as several minutes for connectivity to be reestablished (or as short as 30 seconds to a minute, depending upon the size of your network).

Thanks for your help. We will look at our spanning-tree protocol, but i believe that spanning tree is disabled on our switches. That would, however, explain a lot.

thanks again.
