Figure 3-2. Trunk Groups

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

1.Connect the desired ports of the ELS10-26s together using 10BASE-T crossover cables.

If ELS10-26 A is handling only a small number of users, the A to B Trunk Group could have just two ports per ELS10-26. If ELS10-26 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 a NMS, turn on trunking for the connected ports on each ELS10-26.

For ELS10-26 A, at the LCM prompt: a. Type trunk 2,3 on
