OcNOS-SP : System Management Guide : System Management Configuration Guide : Port Breakout (100G) on Qumran2 : Limitations
Limitations
Port Breakout is supported on all 100g interfaces except the ports having an external phy. These external phy ports can be seen using command show hsl extphy status.
You cannot change one port breakout mode (4X10G, 4X25G) to the other mode (4X10G, 4X25G) directly. You must remove the breakout configuration to change the mode.
Port breakout is not supported on ports which contains sub-interfaces or any other services running over it. To breakout, all services on the interfaces need to be un-configured. After breakout, all the services can be configured on breakout ports.
While configuring port-breakout, you need to reduce the speed of some interface if this error message is displayed: "%% Max egress credit limit reached". This is due to hardware limitation.
