Cisco Software-Defined Access - SDA Use Case Implementation, Operations, & Troubleshooting

Denna kurs utforskar funktionaliteten Cisco Software-Defined Access (SDA) på djupet. 

Som deltagare lär du dig mplementera SDA för olika behov. Kursen behandlar även detaljerna i hur du hanterar och felsöker de olika funktionerna hos underliggande komponenter.

För dig som önskar en utbildning som fokuserar mer på DNA Center rekommenerar vi vår kurs Implementing and Administering DNA Center for Assurance.

Kursen hålls i samarbete med NterOne.

Målgrupp och förkunskaper

Kursen är framtagen för tekniker i en Cisco-baserad nätveksmiljö som arbetar med DNA Center vill gå på djupet med SD-Access.

Som deltagare förutsätts du besitta grundläggande till goda kunskaper om Cisco-baserad routing och switching.

Du behöver även grundläggande kunskaper om mjukvarubaserade nätverk, vanliga säkerhetsbegrepp som AAA, Access Control och ISE, samt viss erfarenhet av Cisco IOS, XE och CLI. Programmeringskunskaper, såsom Python och RestAPI, är en fördel men inget krav.

För att alltid hålla en hög kvalitet på våra teknikkurser använder vi både engelsk- och svensktalande experter som kursledare.

Kursmaterialet är på engelska, med detta innehåll:
