Cisco Systems 3550 manual Bandwidth Utilization

Chapter 1 Product Overview

Front-Panel Description

Bandwidth Utilization

The UTIL mode on the switch shows the current bandwidth in use by the switch. (See Figure 1-4to Figure 1-8.) If all possible port LEDs are green, bandwidth utilization is in the 50 to 100 percent range. Every port LED that is off (black) divides this range by two.

Note The port LEDs on the Catalyst 3550-24PWR switch do not show bandwidth utilization.

Figure 1-4shows the bandwidth utilization percentages displayed by the LEDs on the

Catalyst 3550-12T switch.
