Summary: Very pleased with this Cisco switch.A little apprehensive at first to buy it used I must say, but it worked for the best, no problems so far.Very solid device and more then what I really need right now, but it doesn't matter since I'm thinking on growing.
Summary: These switches are good except for one big problem that affected one of our installations. Cisco acknowledged the bug, but won't work on it any further without us doing a bunch more work on their behalf. We decided that we'll just use another brand of switches. The bug shows up if you try to use the auto voice VLAN feature with phones that don't do CDP. The LLDP option has a bug where the phones will fall off the network after a short time.
Summary: Purchased for use with Cisco SPA 500-series IP phones + UC320. They work together very nicely with minimal effort needed to configure the switch - the auto-discovery set up a separate VLAN for voice, the phones and UC320 just work without drama. It's obviously more expensive than an unmanaged switch - but if you are building a Cisco VoIP system, it's a big savings of time/hassle.
