Automatizarea sarcinilor de gestionare a re\u021belei este acum o sarcin\u0103 extrem de relevant\u0103, astfel c\u0103 programabilitatea trece ca un fir ro\u0219u prin toate produsele Cisco pentru re\u021belele de \u00eentreprindere. Un exemplu de utilizare a API-urilor poate fi interac\u021biunea controller-ului cu sistemul de management al serviciilor IT (ITSM), la care controller-ul trimite analize despre dispozitivele client \u0219i punctele de acces, iar de la acesta prime\u0219te \u00eenapoi o confirmare a intervalelor de timp pentru realizarea actualiz\u0103rii software-ului.
