Configuring Your ELS100-16TX

Usage: bridge [PORT-RANGE [{offonnoBPDU{]]

Port 1 bridging: Transparent Bridging

Port 2 bridging: Transparent Bridging

Port 3 bridging: Transparent Bridging

Port 4 bridging: Transparent Bridging

Port 16 bridging: off

You could also type bridge [PORT-RANGE]to look at a specific range of ports. For example bridge 2-4would display bridging functions for ports 2, 3, and 4.

3.5 ENABLING TRUNKING

If your network configuration requires you to connect two or more ELS100-16TXs (or other devices capable of trunking) together, but the applications you are running over the network require more than 100 Mbps of bandwidth per connection, you can use the built- in trunking feature to increase bandwidth up to 1.6 Mbps, without installing additional hardware on your network.

Trunking is a Cabletron Systems proprietary extension to the 802.1d Spanning Tree algorithm. It enables you to use multiple 100BASE-T Ethernet segments to connect ELS100-16TXs together, while maintaining first-in, first-out ordering of Ethernet packets. In addition, if any of the Ethernet segments configured for trunking become inoperable, those Ethernet segments are automatically bypassed.

Figure 3-1 shows two ELS100-16TXs connected by four 100BASE-T crossover cables. You can connect up to eight ports for sharing the traffic load. Any additional connected ports will become standby ports. The connections must be point-to-point. That is, there cannot be any other devices on the Ethernet segments.
