Network Port LEDs on QFX5120 Switches

 

Each SFP+ port on a QFX5120-32C switch has one LED that shows the link activity of the port (see Figure 1). Table 1 describes the link activity LED on the SFP+ ports on QFX5120-32C switches.

Each QSFP28 port on a QFX5120-32C switch 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. Table 2 describes the LEDs on the QSFP28 ports on QFX5120-32C switches.

Each SFP28 port on a QFX5120-48Y switch has two LEDs that show the link activity and status of the port (see Figure 4). Table 3 describes the LEDs on the SFP28 ports on QFX5120-48Y switches.

Each QSFP28 port on a QFX5120-48Y switch has four LEDs that show the link activity of the port (see Figure 3). The first LED operates when the port is not channelized; the other three LEDs operate when the port is channelized. Table 2 describes the LEDs on the QSFP28 ports on QFX5120-48Y switches.

Each BASE-T port on QFX5120-48T switches has one LED that indicates the status of the port (see Figure 5). Table 4 describes the LEDs on the BASE-T ports on QFX5120-48T switches.

Each QSFP28 port on QFX5120-48T switches has one LED that indicates the status of the port (see Figure 6). Table 5 describes the LEDs on the QSFP28 ports on QFX5120-48T switches.

State and Description

Link activity

Green

  • Blinking—The port and the link are active, and there is link activity.

  • On steadily—The port and the link are active, but there is no link activity.

  • Off—The port is not active.

Description

1–4

Unlit

Off

The port is administratively disabled, there is no power, the link is down, or there is a fault.

1

Green

On steadily

A link is established (either 100 Gbps or 40 Gbps, nonchannelized) but there is no link activity. When this LED is on, the LEDs in positions 2 through 4 are off.

Blinking

A link is established (either 100 Gbps or 40 Gbps, nonchannelized) and there is link activity.

2–4

Green

On steadily

A 25-Gbps or 10-Gbps link is established in channelized mode, but there is no link activity.

Blinking

A 25-Gbps or 10-Gbps link is established in channelized mode, and there is link activity.

All

Amber

Blinking

The beacon function is enabled on the port.

Note: The beacon function is not available on QFX5120-32C switch.

State and Description

Status

Green

  • On steadily—The port is operating in 10-Gbps speed, but there is no link activity.

  • Blinking—The port is operating in 10-Gbps speed and there is link activity.

Yellow

  • Blinking—The port is operating in 1-Gbps speed and there is link activity.

  • On steadily—The port is operating in 1-Gbps speed, but there is no link activity.

  • Blipping—The beacon function is enabled on the port.

Unlit

The port is administratively disabled, there is no power, the link is down, or there is a fault.

State and Description

Status

Green

When the port 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 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 channelized interfaces.

When the ports 50 and 51 are channelized and 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.

Amber

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

  • On steadily—One or more breakout link is established, but there is no link activity on any of the channelized interfaces.

  • Blinking—One or more breakout link is established and there is link activity on at least one of the channelized interfaces.

  • Blipping—The beacon function is enabled on the port.
