Excerpt: We bought 3 of them and have been kicking ourselves ever since. We didn't realize the don't come with SNMP support, or it's so deeply buried in the user interface it'll never surface. One of these switches went rogue on us until we could isolate how to keep it from doing so. They use a proprietary discovery protocol, forcing us to dig around to find a way to get them to cough up information on connected devices, etc. Still looking.
