show the bandwidth utilization percentages displayed by the right-most
LEDs.
Note
The Catalyst 2950 LRE switch LEDs do not give utilization status.
If all LEDs on a Catalyst 2950-12, 2950-24, 2950C-24, 2950SX-24, or 2950T-24 switch are green (no
amber showing), the switch is using 50 percent or more of the total bandwidth. If the far-right LED is
off, the switch is using more than 25 but less than 50 percent of the total bandwidth, and so on. If only
the far-left LED is green, the switch is using less than 0.0488 percent of the total bandwidth. (See
amber showing), the switch is using 50 percent or more of the total bandwidth. If the far-right LED is

On an LRE switch, the LEDs for Uplink Port 1 and Uplink Port 2 correspond either to the SFP module port or to the
10/100/1000 port, depending on which is active.

If an LRE switch senses connections to both ports, by default, the switch chooses the fiber-optic connection over the copper
connection.
