For dynamic breakout (per-port level breakout), the interface breakout command splits high bandwidth 40G ports into four 10G breakout ports and 100G ports into four 25G breakout ports. The breakout ports are identified as Ethernet <slot>/<front-panel-port>/<breakout-port> . For example, per-port level breakout ports can be identified as Ethernet 1/2/1, Ethernet 1/2/2, Ethernet 1/2/3, and Ethernet 1/2/4.
When one or more 40G interfaces of the module are broken-out at the per-port level, the configuration for the interfaces are removed when the command is executed.
Note
A per-port level breakout does not require the module to be reloaded.
