Network Port LEDs on QFX5120 Switches

 

Network Port LEDs on QFX5120-32C Switches

Each SFP+ port on QFX5120-32C switches has one LED that shows the link activity of the port (see Figure 1). See Table 1 to learn more about that LED.

Each QSFP28 port on QFX5120-32C switches has four LEDs that show the link activity of the port (see Figure 2). The first LED operates when the port is not channelized; the other three LEDs operate when the port is channelized. See Table 2 to learn more about those LEDs.

State and Description

Green

When the port is not channelized and is configured to operate as one 100GbE or 40GbE interface:

  • On steadily—The port is operational, but there is no link activity.

  • Blinking—The port is operational and there is link activity.

When the port is channelized and is configured to operate as two 50GbE interfaces:

  • On steadily—The port is operational, both the interfaces are operational, but there is no link activity.

  • Blinking—The port is operational and there is link activity on at least one of the interfaces.

When the ports 50 and 51 are channelized and are configured to operate as four 25GbE or 10GbE interfaces:

  • On steadily—All four breakout links are established, but there is no link activity on any of the channelized interfaces.

  • Blinking—All four breakout links are established and there is link activity on at least one of the channelized interfaces.
