If a port status LED is blinking green, what does that indicate?

A blinking green LED typically indicates that there is active traffic flow on the port. This visual signaling shows that data packets are being transmitted and received, suggesting that the connection is functioning properly and is in use.

In contrast, a steady green LED would usually signify a stable connection without traffic fluctuations, while a linked-down state or configuration issues would show different LED behavior, such as being off or displaying a steady status indicating no connection. Understanding LED indicators on networking devices is vital for troubleshooting and monitoring device performance, and recognizing that a blinking green light means traffic flow is crucial for network management.
