Description
1
QSFP+ ports
Two quad small form-factor pluggable (QSFP+) 10Gbps/40Gbps Ethernet interfaces as defined by the IEEE 802.3ba standard.
The two physical QSFP+ interfaces operate at 40Gbps each. The firewall uses the ports to forward all dataplane logs to an external system, such as Panorama, Firewall Data Lake, or a syslog server.

PAN-OS 10.0 and later:
To breakout the two interfaces into individual 10G ports, you must configure the LFC as lfc1/1 and use the PAN-QSFP-40GBASE-SR4. Lfc1/1 auto-configures ports 1-4 in the first interface and auto-configures ports 5-8 in the second interface for up to eight usable 10G ports. You can use any number of the eight ports for your configuration. If four ports (one ethernet interface) is used, the LFC provides a maximum transfer rate of 40Gbps. If all eight ports (both ethernet interfaces) are used, then the LFC provides a maximum transfer rate of 80Gbps.
To properly breakout the QSFP+ ports, you must use the PAN-QSFP-40GBASE-SR4 transceiver and an appropriate passive breakout cable.
When not using a breakout deployment, you must configure the LFC as lfc1/9. Lfc1/9 auto-configures port 9 in the first interface and auto-configures port 10 in the second interface for up to two usable 40G ports. You can use one or both interfaces to provide up to 40G or 80G connectivity in this way.
In both of the above deployments, the linked device must be set to use LAG for all ports attached to the LFC. The LFC does not currently support LACP.
Ports 1 and 9 share the same LED and ports 5 and 10 share the same LED. Port transfer rate is differentiated by color. Green indicates 10Gbps and yellow indicates 40Gbps.
PAN-OS 9.1 and earlier:
You can only use ports 1 or 9 in PAN-OS versions 9.1 and prior. Ports 2-8 and 10 are not available. Configuring the LFC as lfc1/1 operates the first interface as port 1 at 10G (Green LED). Configuring the LFC as lfc1/9 operates the first interface as port 9 at 40G (Yellow LED). The second interface is not used in either configuration. The LFC does not support LAG and LACP.

LED dashboard
Five LEDs that provide LFC status. For details on the LEDs, see Interpret the PA-7000 Series Firewall Log Forwarding Card (LFC) LEDs.

LFC installation and removal hardware
Screws and levers used to install and remove the LFC. There are thumb screws and double lever release latches on each side of the card. Each inner ever contains a micro-switch and when you simultaneously pull both inner levers outward to release the outer ejector
