Figure 3-2. Trunk Groups

To enable trunking for the example shown, perform the following:

1.Connect the desired ports of the ELS100-16TXs together using 100BASE-T crossover cables.

If ELS100-16TX A is handling only a small number of users, the A to B Trunk Group could have just two ports per ELS100- 16TX. If ELS100-16TX B and C are expected to interconnect many users, you could use up to eight ports in the B to C Trunk Group.

2.Using LCM or an NMS, turn on trunking for the connected ports on each ELS100-16TX.

For ELS100-16TX A, at the LCM prompt: a. Type trunk 2,3 on
