Breakout
Ett breakout-interface är ett fysiskt höghastighetsinterface som görs om till flera logiska interface av lägre hastighet.
Inkoppling
I praktiken kopplas enbart 1 speciell SFP (fiber alt. DAC) in i switchen som går till en breakoutkabel. En breakoutkabel delar sig i flera delar. Kabeln kan vara fristående från SFPn eller integrerad i SFPn. Breakout via en fiber-SFP stöder finns för både multimode och singlemode.
Hastigheter
Vilka hastigheter som stöds beror på vilka hastigheter som porten stöder och därmed vilka kanaler (engelska: lanes) som ligger bakom hastigheten. Exempelvis är en 40 Gbit/s-interface egentligen 4x10 Gbit/s, vilket gör att 1 40 Gbit/s-interface kan bli 4x10Gbit/s-interface via breakout.

Konfiguration
Breakout konfigureras ej direkt på interfacet utan i global config-läge.
Modulläge
Det går att konfigurera en hel modul i breakoutläge. Då startar modulen om vid konfiguration.
switch# configure terminal
switch(config)# interface breakout module 1
Module will be reloaded. Are you sure you want to continue(yes/no)? yes
! Återställ
no interface breakout module module_numberPer-interfaceläge
Ingen omstart av modul sker när det konfigureras i interfaceläge.
