The Cisco Nexus 7000 Series Switches and the Cisco Nexus 7700 Series Switches support the Breakout feature. Breakout enables
a 40 Gigabit Ethernet port to be split into four independent and logical 10 Gigabit Ethernet ports. Breakout is supported
on an active Twinax (1 to 10 m) cable or a multimode fiber cable (SR4 optic cable with an MTP connector or an MPO connector).
For the list of transceivers that are supported on Cisco Nexus 7000 Series switches, refer the Cisco Nexus 7000 Series NX-OS Release Notes.
Starting from Cisco NX-OS Release 8.4(1), the Breakout feature also enables a 100 Gigabit Ethernet port to be split into four
independent and logical 25 Gigabit Ethernet ports. This feature is supported only on the Cisco Nexus 7700 F4-Series 30-port
100-Gigabit Ethernet I/O module (N77-F430CQ-36).
Note
|
When the Breakout feature is configured, the configuration for the corresponding interface is removed.

The Breakout feature that enables a 40 Gigabit Ethernet port to be split into four independent and logical 10 Gigabit Ethernet
ports is supported in the following modules:
-
Cisco Nexus 7000
F3-Series 12-Port 40 Gigabit Ethernet Module
-
Cisco Nexus 7000
M2-Series 6-Port 40 Gigabit Ethernet Module
-
Cisco Nexus 7700
F3-Series 24-Port 40 Gigabit Ethernet Module
Starting from Cisco NX-OS Release 8.0(1), the Breakout feature that enables a 40 Gigabit Ethernet port to be split into four
independent and logical 10 Gigabit Ethernet ports is also supported in the following modules:
Starting from Cisco NX-OS Release 8.3(1), the Breakout feature that enables a 40 Gigabit Ethernet port to be split into four
independent and logical 10 Gigabit Ethernet ports is also supported in the Cisco Nexus 7700 M3-Series 12-port 100-Gigabit
Ethernet I/O module.
Starting from Cisco NX-OS Release 8.4(1), the breakout feature that enables splitting of both 40 Gigabit and 100 Gigabit ethernet
ports, based on the transceiver at the interface, is supported on the Cisco Nexus 7700 F4-Series 30-port 100-Gigabit Ethernet
I/O module. The 40 Gigabit Ethernet port can be split into four independent and logical 10 Gigabit Ethernet ports. The 100
Gigabit Ethernet port can be split into four independent and logical 25 Gigabit Ethernet ports.
