The procedure for configuring a breakout port interface or subinterface for supported
NGFWs.

Breakout ports on supported NGFWs enable you to split high-speed
physical interfaces into multiple lower-speed logical interfaces to maximize ports
on your NGFWs. When you configure breakout ports, you can divide a single 100 Gbps
or 40 Gbps interface into multiple 25 Gbps or 10 Gbps connections respectively
(typically up to four subinterfaces), allowing you to connect more devices without
requiring additional physical ports. For example, configuring ethernet1/1 as
breakout type allows you to create ethernet1/1/1, ethernet1/1/2, ethernet1/1/3, and
ethernet1/1/4 interfaces.
Supported NGFWs implement breakout
functionality through software configuration that divides the physical interface
lanes into separate logical interfaces, each operating independently with its own
interface settings. This configuration proves particularly useful in data center
environments where you need to connect several lower-bandwidth devices to your NGFW
but have limited physical interface availability. The NGFW treats each breakout port
as a separate logical interface that you can configure with distinct security
policies, routing settings, and network zones.
Before you can begin configuring breakout ports
for your NGFWs, confirm that they meet the following requirements
