breakout mode

Configures breakout mode for the supported connectors.

Syntax

breakout mode { 4x10g | 4x25g | 4x1g }

no breakout

Command Default

By default, breakout mode is not configured.

Parameters

4x10g: Configures four 10g breakout interfaces on a port.
4x25g: Configures four 25g breakout interfaces on a port.
4x1g: ( SLX 9250 only) Configures four 1g breakout interfaces on a port.

Modes

Hardware connector configuration mode

Usage Guidelines

You do not need to reboot a device for the breakout configuration change to take effect.

When you configure a breakout mode on an Ethernet port, the original interface is deconfigured and deleted. The new breakout interfaces in the default configuration are created automatically. These new interfaces are identified with the name of the original interface followed by a suffix. For example, the breakout interfaces of connector 0/25 have the following naming convention:

interface ethernet 0/25:1
interface ethernet 0/25:2
interface ethernet 0/25:3
interface ethernet 0/25:4

Use the no form of the command to reset the port to non-breakout mode. When you run the no form of the command, the breakout interfaces are deconfigured and deleted. The original Ethernet interface in the default configuration is created automatically.

To switch from one breakout mode to another, set the port to non-breakout mode and then run the command to configure the new breakout mode.

( SLX 9250) This platform supports only the 4x1g breakout mode, which supports the redundant management interface feature. This feature is used with Mellanox network adapters and 1GB copper SFPs.

( SLX 9150, SLX 9540, SLX 9640) These platforms support the 4x10g and 4x25g breakout modes. The number of connectors and connector IDs that support the breakout function varies by platform. For more information, see the Technical Specifications guide for your platform.

Examples

This example configures 4x25g breakout mode on connector 0/25 on SLX 9640.

device(config)# hardware
device(config-hardware)# connector 0/25
device(config-connector-0/25)# breakout mode 4x25g

This example reverts a port to non-breakout mode on SLX 9640.

device(config)# hardware
device(config-hardware)# connector 0/25
device(config-connector-0/25)# no breakout

This example configures 4x10g breakout mode on connector 0/25 on SLX 9640.

device(config)# hardware
device(config-hardware)# connector 0/25
device(config-connector-0/25)# breakout mode 4x10g

This example configures 4x1g breakout mode on connector 0/15 on SLX 9250.

device(config)# hardware
device(config-hardware)# connector 0/21
device(config-connector-0/15)# breakout mode 4x1g
