I need help figuring out how the VLANs are configured on our HP ProCurve switch. I've never seen such a setup before, but there are over 20 VLANs, one for each department. That's fine, so far. Normally the VLANs I've worked with are segregated and completely independant. These VLANs seem to be configured in such a way that all VLANs are able to communicate with each other.
Can someone help me figure out either how this is possible, or guide me to the setting on that ProCurve switch. I looked around on the web interface, but could not find any such settings that bridge the VLANs.
