This topic lists the guidelines and restrictions that apply when you configure the breakout mode.
-
If you're using a Q100-based Cisco 8200 Series Router and want to set up a 4x10G breakout configuration, you need to use even-numbered ports from 24 to 35. These include ports 24, 26, 28, 30, 32, and 34. Once you do this, the system automatically disables the odd-numbered ports in this range — ports 25, 27, 29, 31, 33, and 35.
-
Use the hw-module port-range command to set the port range for the breakout configuration in the global configuration.
-
To remove the global hw-module port-range configuration, you must first remove the breakout 4x10 configuration under the controller.

On the Cisco 8812 router, the 88-LC0-34H14FH line card can have only three ports per Interface Group (IFG) when operating in 4x10 GbE or 4x25 GbE breakout configuration mode. This helps prevent the QOS-DPA_QOSEA-2-TMPORT_PROG_ERROR issue, which creates partial interfaces during configuration mode.
