The TPE-80WS is an extremely capable switch. There are advanced functions that you would not normally expect from a PoE switch. I found that it fit into my existing high-bandwidth network quite nicely. In fact, I allowed it to be the root bridge for the RSTP setup. The PoE support is outstanding and is very simple to use since it auto detects the power draw from any PoE device connected.
The WebSmart UI is also nicely laid out and provides configuration for all of the features in intuitive screens. TRENDnet also separated the status pages from the settings pages to allow for easy monitoring without the need to view the existing settings options.
Breaking out 802.3ad link aggregation from the standard trunking page is also a nice touch. Many devices might support trunking, but not the full 820.3ad protocol and vice versa. With the TPE-80WS you can enable the proper link aggregation support for each of your devices. This is something that not even the TEG-240WS can do as it only supports trunking. IGMP, Broadcast Storm and SNMP support round out this excellent product.
In all, as an IT Manager I would consider the TPE-80WS a bargain at $250.
