Cisco NX-OS for IOS Administrators - DCNXA Course Outline

(5 Days) - Learning Credits Accepted


The Cisco NX-OS for IOS Administrators (DCNXA) v2.0 is a five-day instructor-led course designed for network administrators who are migrating from a traditional Cisco IOS environment to routing and switching platforms that use the Nexus Operating System (NX-OS). This course covers the key components and procedures you need to know to install and manage Cisco Nexus 9000, 7000, 5000, 2000 and 1000v series switches. This course will also cover important troubleshooting procedures for these platforms as well.
