Port Breakout (100G) on Qumran2

OcNOS-SP : System Management Guide : System Management Configuration Guide : Port Breakout (100G) on Qumran2

Overview

Port breakout enables 100GbE ports to be broken out into 4x10GbE, 4x25GbE, and 2x50GbE ports through a secure, highly reliable breakout cabling solution. Networks require a mix of 10Gb, 25Gb, 40Gb, and 100Gb Ethernet interface speeds able to utilize the widest range of flexible connectivity options and it require a variety of cost-effective cabling options for both addressing connectivity and allowing for simple migrations as network speeds and density requirements evolve.

Port breakout feature provides flexibility in splitting 100G to 4X10G, 4X25G, 2X50G, and vice-versa. 100G splittable ports are called control ports. Ports which are members of a control port are called subsidiary ports. When you do port breakout on 100g (ce3) port into 4X10g, the original port (ce3) will be removed and four 10g ports will be added as ce3/1, ce3/2, ce3/3, and ce3/4. On this breakout port you can do the all L2 and L3 features like on a normal port.

When port breakout is un-configured, the breakout ports (ce3/1, ce3/2, ce3/3, ce3/4) will be removed and the original port (ce3) will be added back.

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.

Topology

Sample Port Breakout Topology

Port Breakout 4X10g
