Port Breakout Configuration
This chapter contains an overview of splitting single 100G port to 4x10G ports.
Overview
Port Breakout system enables numerous 100GbE ports to be broken out into 4x10GbE, 4x25GbE, 2x50GbE ports through a secure, highly reliable breakout cabling solution. Today’s large-scale virtualized datacenter networks require a mix of 10Gb, 25Gb, 40Gb and 100Gb Ethernet interface speeds able to utilize the widest range of flexible connectivity options. These same networks require a variety of cost-effective cabling options for both addressing connectivity and allowing for simple migrations as network speeds and density requirements evolve. As data centers scale and bandwidth demands increase, the networking infrastructure must be capable of scaling with it. Port Breakout feature provides flexibility in splitting 100G to 4x10G, 4x25G, 2x50G cabling and vice-versa whenever requires, and hence provide Administrator a great flexibility in choosing the port speed as per their requirement. A Port Breakout group consists of 4 ports, first port will be control port and the rest 3 are subsidiary ports. Naming of Control port and its subsidiary port is as below
xe50/1, xe50/2, xe50/3, xe50/4
In xe50, numeral 50 indicates the slot of the port on a board and numerals after “/” indicates port numbers on that slot. First port (interface 50/1 in above example) is always control port whereas the rest 3 ports (ports 50/2, 50/3 and 50/4) are subsidiary ports. Only Control port can become 100G port.
Currently below breakout options are available
100G ports
100G to 4x10G breakout ports
100G to 4x25G breakout ports (due to HW limitation Autoneg isn't supported)
100G to 2x50G breakout ports (due to HW limitation Autoneg isn't supported).
Note: There are some configuration restrictions for Subsidiary ports such as:
1. Port breakout enable/disable is not allowed on Subsidiary ports.
2. Speed, Duplex configurations are not allowed on InActive Subsidiary ports.
3. One control port and subsidiary ports will be supported in 100g to 2x50G breakout
For Example: Port XE1/1(control port) and XE1/3(subsidiary port) will be active out of 4 ports.
Terminology
Following is a brief description of terms and concepts used to describe port breakout.
Ctl: Control port
A 100G splitable port is called Control port.
Brk: Port Breakout
A control port which is split into 4x10G 4x25G or 2x50 ports.
Subsidiary ports
Ports which are members of Control Port, A subsidiary port can be Active or InActive
IA: InActive Ports
Subsidiary ports whose control port is not configured for “Port Breakout”
Pre-Requisite
From OcNOS version 5.1 onwards, before doing the Port breakout we need to reserve the VLANs using the CLI vlan-reservation vlan-id/vlan-range.
The main purpose of this vlan-reservation is when port breakout is not required, then Maximum vlans upto 4062 can be used for bridge configuration.
Note: Once VLANs are reserved, those vlans cannot be used for bridge configuration.
Note: We can release the reserved vlans by unconfiguring the no port breakout enable and no vlan-reservation vlan-id/vlan-range.
Note: Released VLANs can be used for bridge configuration.
Configuring vlan-reservation
Configuring Port Breakout (40G to 4x10G) is provided in below section.
 
#configure terminal
Enter configure mode.
(config)# vlan database
Enter vlan database
(config-if)# vlan-reservation 4050-4058
Specify the vlan-range that should be reserved for interface port Breakout.
(config-if)#exit
Exit vlan database.
 
Unconfiguring vlan-reservation
Configuring Port Breakout (40G to 4x10G) is provided in below section.
 
#configure terminal
Enter configure mode.
(config)# vlan database
Enter vlan database
(config-if)# no vlan-reservation 4050-4058
Specify the vlan-range/id that should be released
(config-if)#exit
Exit vlan database.

Here xe50/1 is a control Port whereas xe50/2, xe50/3 and xe50/4 are their subsidiary ports. The out-put shows only xe50/1 is active (interface up and running) whereas other ports are inactive (interface up but not running).
Below Outputs after applying port-breakout configured on xe50/1:
