NI PXI 8176 broadcasting Version 2 Spanning Tree Updates

[NanGlenn]

I am not the owner of this device, but I am in IT. We had an NI PXI8176 suddenly start broadcasting version 2 spanning tree protocols over the network... this is a mystery to us. Has anyone ever seen this, or have theories why it would do this?
thanks

I'm not very familiar with spanning tree protocols, but I thought that they were for network bridges and switches.

Have you had any viruses on that PXI-8176? Think of the PXI-8176 as a laptop in a different form factor when troubleshooting this kind of stuff. This sounds like an OS/virus/network issue.

Good luck.

They ARE usually used by routers and switches. The question is what could suddenly make this device start acting like a switch? It had the latest McAfee virus protection on it.
