1G Breakout Ports

The 1G Breakout Ports feature enables the configuration of 1-Gbps speed on 10-Gbps subports dynamically without performing reload.

The 1G Breakout Ports feature does not mandate all the breakout subports to be configured at the same speed, so that each subport can work according to the configured speed setting (10-Gbps or 1-Gbps speed).

Note: To enable the 1G Breakout Ports feature, you must perform a reload. After 1G Breakout Ports is enabled, port density can be increased or decreased without performing a reload.

Consider the following details when using the 1G Breakout Ports feature:

  • All breakout ports work at the same speed; however, all breakout subports can be configured with an individual speed.
  • A new user configuration using the speed-duplex 1000-full command on a breakout subport forces the speed configuration on the breakout subport irrespective of the type of optics.
  • Speed settings are changed dynamically and do not require a reboot.
  • Each breakout subport works according to its speed settings.
  • The 1G Breakout Ports feature is supported on ICX 7850 and ICX 7550 switches only.
  • The 1G Breakout Ports feature is supported with two types of optics only. For details of these supported media types, refer to the RUCKUS Ethernet Optics data sheet.
  • Auto-negotiation must be disabled when using the 1G Breakout Ports feature.
  • The port must be configured in uplink mode before enabling breakout on ICX 7550-24F, ICX 7550-48F, ICX 7550-24ZP, and ICX 7550-48ZP models.
  • The 1G Breakout Ports feature is limited to breakout subports and not applicable for ports configured as stacking ports.
  • You can configure breakout ports in global configuration mode, and after the successful configuration and activation of breakout, the subports are available for configuration.
