Configure Breakout Ports

You can break a port into multiple interfaces, such as breaking one 40G port into four 10G ports. You can also revert the breakout.

In SLX-OS, you can use the show running-config hardware command to see whether breakout mode is configured for a device.

You can break a port into the following modes: one 10g port, one 25g port, one 100g port, two 40g ports, two 50g ports, four 10g ports, and four 25g ports.

The breakout interfaces you create are identified by the name of the original interface followed by a suffix.

When you run revert a breakout, the breakout interfaces are deconfigured and deleted. The original Ethernet interface in the default configuration is created automatically.

To break a port into multiple ports, run the following command.

# efa inventory device interface set-breakout –-ip 10.x.x.x 
–-if-type eth –-if-name 0/52 –-mode 4x10g

This example breaks interface 0/52 into four 10g ports.

To revert the breakout of multiple ports to the original configuration, run the following command.
```
# efa inventory device interface unset-breakout –-ip 10.x.x.x 
–-if-type eth –-if-name 0/52
```
This example removes breakout mode on interface 0/52.
