Web Smart Configuration
Accessing the Web Smart Configuration is simple, you browse to the IP address that you chose for the TEG-240WS and it opens the login page.
One thing to note and I hope that TRENDnet considers fixing this in future firmware releases; the connection to the switch is not secure and I feel it would improve the product greatly to add an SSL connection to the Web Smart pages. This would protect the configuration better than the standard connection used currently.
Once you are in you come to the status screen. Here is all of the basic information about your TEG-240WS at-a-glance.
Keeping under the system heading we move down to System Settings. Here you can change the network information such as IP address, subnet, gateway, system and location name, as well as the login timeout.
Moving more steps down we come to the Trap Settings page. As we mentioned above there is a monitor in the Web Smart Management Utility. This page allows you to setup specific events for the TEG-240WS to send information to the monitor on.
Password setting is self explanatory as is the statistics page; the nice thing about the statistics page is that you can view individual ports in greater detail by clicking on the port number.
Factory reset, backup settings, firmware upgrade and system reboot round out the System heading.
Next up is the Advanced header. Here your only option is for setting up IGMP Snoop Settings. IGMP stands for Internet Group Management Protocol and it is intended to reduce the flood of multi-cast traffic on a network. Enabling this in a typical network can help to improve performance globally by cutting down on the amount of traffic set to all ports on the switch by only sending IGMP Multi-Cast traffic to systems with IGMP clients actively listing on the network.
Of course, multicast traffic is not entirely bandwidth intensive and enabling snooping puts a larger demand on the router, but it is an important function as we move into the world of media extenders and streaming HD TV and Movie servers in our home networks. For the LAN Party setup this is not completely needed as the server and clients will be actively connecting anyway. In an enterprise environment this is an important feature if you are running video or remote installation servers as it will over all improve performance across the network.
Moving up one more header, we come to the Setup header. Under Setup we find the most interesting options for the configuration of the TEG-240WS. At the top of the list is the Port Settings page. Here you can manually adjust the speed and flow control of each and every port to suit the needs of the LAN you are building. The Flow Control option is available for each port but should not be used while QoS is setup as it can prevent QoS from working properly. There will be times that you may need to run Flow Control though (for 802.3x compatible devices as you will see below).
The 802.1q VLAN settings are up next. Here you can create multiple symmetrical and asymmetrical Virtual LANs with tagged and untagged frames. You can also establish common ports to allow for access to a single server or point of connection (e.g. for Internet). This is a powerful function that has uses in enterprise networks but can also be handy for LAN Party setups and even more advanced home networks; segregating Console Game traffic from a home office network, segregating an internal LAN for game play without external access (for younger kids) or simply breaking the 24 ports into a regular network and a testing environment.
The TEG-240WS also supports trunking or link aggregation for increased bandwidth.
You are able to setup a maximum of four trunks with up to eight ports in each. When setup the trunks combine the ports for greater through put. I found this especially handy with my Thecus 5200 Pro NAS. Although I ran into problems using the 802.3ad setting; when 802.3ad was enabled on the 5200 Pro and trunking was setup on the TEG-240WS I was not able to connect to the 5200 Pro. However, by setting up load balancing on the 5200 Pro and trunking on the TEG-240WS I was able to significantly improve performance of the 5200 Pro.
Another excellent feature of the TEG-240WS, although one that has no translation into the home or LAN Party arena, is port mirroring. By setting up port mirrors you can forward all packets from a particular port to another port for study. You can set up mirroring for transmitted, received or all packets.
802.1p otherwise known as QoS (Quality of Service) is another feature of the TEG-240Ws that is worthy of mention. In this section you can individually adjust for the QoS level on a per port basis. By setting higher and lower QoS levels you can shape the way traffic moves through your network. This can be good in a home/home office environment where there might be servers or storage that need a higher priority than the kids browsing the internet or gaming. It works inside VLANs but will not work if you have Jumbo Frame enabled.
Broadcast Storm Control is excellent to prevent overloading the TEG-240WS with broadcast packets (like DHCP requests etc). Although this feature is disabled by default, turning it on can improve enterprise performance by setting a limit on the amount of broadcast packets allowed through the TEG-240WS.
Jumbo Frame control allows devices on your network that are capable of Jumbo Frames to combine packets (frames) of the same type, like video, into a single larger frame. By enabling this on the TEG-240WS and any Jumbo Frame aware devices you can improve performance by reducing the processing time of a larger number of smaller packets. One down side to using this feature is that you cannot individually adjust QoS per port when this is enabled.
