Examples of Port

Example 1: Fully

Loaded System

The configuration of trunks or DAS pairs does not change the port

numbering scheme shown in displays such as Ethernet statistics displays

or bridge port displays. If you have created trunks or FDDI DAS pairs,

however, be aware that a group of ports is associated with each trunk or

DAS pair. Therefore, a display such as a bridge port display groups the

ports associated with each trunk or DAS pair. See the Command

Reference Guide for examples of the bridge port display commands.

This section provides sample configurations that illustrate port numbering

on the system.

For a fully loaded system (4 occupied slots) with Fast Ethernet ports, the

ports are numbered 1 through 24, starting top left to top right, and then

continuing bottom left to bottom right, as shown in Figure 6. (The figure

shows the 10/100BASE-TX module.)
