Port LEDs and Modes
Each 10/100 port and module slot has a port LED. These port LEDs, as a group
or individually, display information about the switch and about the individual
ports. The port modes (Table 1-6) determine the type of information displayed
through the port LEDs.
To select or change a mode, press the Mode button until the desired mode is
highlighted. When you change port modes, the meaning of the port LED colors
also changes. Table 1-7 and Table 1-8 explain how to interpret the port LED
colors after you change the port mode.
Note To change the port mode in the Catalyst 3548 XL switch, press the
Mode label.
