What does a solid green LED indicate on the speed setting for a port?

A solid green LED on the speed setting for a port indicates that the port is operating at 100 Mbps. In networking equipment, particularly on switches and routers, the LEDs serve as visual indicators of the status and speed of the connections.

When the LED is solid green, it signifies that the connection is active, and when specifically considering the port speed settings, solid green typically denotes a speed of 100 Mbps. This is consistent across many Cisco devices and is part of their standard method of visually representing the operational state of network ports.

In contrast, a solid yellow or amber light would commonly indicate lower speeds, such as 10 Mbps, and a flashing light might indicate data transmission activity. No light at all typically signals that there is no connection established, which rules out the possibility of a solid green indicating a lack of connectivity.
