You could also type bridge [PORT-RANGE] to look at a specific
range of ports. For example bridge 2-4 would 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.
