QFX5130-32CD Port Panel

The port panel of the QFX5130-32CD has 32 high-speed ports that support transmission at 400-Gbps, 100-Gbps, or 25-Gbps speeds. It also has 2 dedicated ports for 10 Gbps.

Note:

When you use the Reset button, only the device gets rebooted and there is no change to the existing configuration of the switch. The device does not return to the factory-default configuration.

Network Ports

The QFX5130-32CD network ports (0 to 31) support:

  • 400-Gbps QSFP-DD direct attach copper (DAC) cables

  • 400 Gbps active optic cable (AOC) (starting in Junos OS Evolved Release 20.4R1)

  • 100-Gbps QSFP28 transceivers

  • 100 Gbps active optic break outcables (AOCBO) QSFP28 to four SFP25G interfaces

  • 40 Gbps QSFP+ to 10 Gbps SFP+ DACBO cables (40 Gbps breaks out to 10 Gbps)–Junos OS Evolved Release 20.4R1 and later

The 10-Gbps network ports 32 and 33 support small form-factor plus (SFP+) transceivers.

Setting Port Speed and Channelization

The default port speed for ports 0 through 31 is 400 Gbps. Only QSFP-DD optics inserted in these ports will link without configuration. See Table 1.

Table 1: QFX5130-32CD Port Speed Autodectection

Transceiver

Sets Default Speed to

QSFP-DD

400 Gbps, link up

QSFP28

400 Gbps, link down

QSFP

400 Gbps, link down

SFP+ (ports 32 and 33 only) and management port

10 Gbps, link up

Note:

The QFX5130-32CD does not support autonegotiation between devices.

If a port already has a speed configured, you can manually configure the ports. To set the speed, use the set interfaces xe-0/0/0 speed speed CLI command in configuration mode. For example, to set port 2 to 100 Gbps:

Note:

On QFX5130-32CD devices, there is a single FPC and PIC, which is always 0.

You can channelize the port into 4 independent 25-Gigabit or 10-Gigabit Ethernet interfaces by configuring the number of sub-ports and speed. To do this, you can use the set interfaces et-0/0/x speed (25G | 10G) number-of-sub-ports number-of-sub-ports command. For example, to configure a 40-Gbps port into four independent 10-Gbps interfaces:

QFX5130-32CD Network LEDs

The high-speed QSFP-DD network ports use a single bi-colored LED to indicate link status, activity on the link, or a fault condition. The 10-Gbps SFP+ ports have separate bi-colored LEDs; the left LED indicates link and activity and the right LED indicates fault conditions. See Figure 1.

Table 2 describes the various states of the network port LED for the QSFP-DD high-speed ports. Table 3 describes how to interpret the link and activity LED and the status LEDs for the SFP+ ports.

Description

Unlit

Off

No

Off is the default mode. The LED can be unlit even when power is present and a transceiver is present in the port.

  • The port is administratively disabled.

  • The link is down.

  • A fault is detected on the link.

Yes

The port is administratively disabled.

Green

On steadily

No

A 400-Gbps or 100-Gbps link is established, but there is no activity.

Yes

All channels or subports have links established but there is no activity.

Flashing

No

A 400-Gbps or 100-Gbps link is established, and there is link activity.

Yes

All channels or subports have links established and there is link activity.

All LEDs blipping (slow flashing)

Either

Indicates that the beacon feature is activated (service request).

Amber

Blinking

Either

One or more interface or connection errors have occurred.

Flashing

Yes

At least one channel or subport has a link, but not all channels or subports have links established.
