Configure ACLs on AOS-CX switches to select given traffic
Apply static ACLs to interfaces to meet the needs of a particular scenario
Examine an ACL configuration and determine the action taken on specific packets
Deploy AOS-Switches in single-area and multi-area OSPF systems
Use area definitions and summaries to create efficient and scalable multiple area designs
Advertise routes to external networks in a variety of OSPF environments
Promote fast, effective convergence during a variety of failover situations

Understand the use of user roles to control user access on AOS-CX switches
Implement local user roles on AOS-CX switches and downloadable user roles using a ClearPass solution
Implement 802.1X on AOS-CX switch ports
Integrate AOS-CX switches with an Aruba ClearPass solution, which might apply dynamic role settings
Implement RADIUS-based MAC Authentication (MAC-Auth) on AOS-CX switch ports
Configure captive portal authentication on AOS-CX switches to integrate them with an Aruba ClearPass solution
Combine multiple forms of authentication on a switch port that supports one or more simultaneous users

This course teaches you the advanced skills necessary to implement and operate enterprise level Aruba campus switching solutions. You will build on the skills you learned at the Associate level to configure and manage modern, open standards-based networking solutions using Aruba's OS-CX routing and switching technologies. In this course, participants learn about ArubaOS-CX switch technologies including: securing port access with Aruba's dynamic segmentation, redundancy technologies such as Multiple Spanning Tree Protocol (MSTP), link aggregation techniques including Link Aggregation Protocol (LACP) and switch virtualization with Aruba?s Virtual Switching Extension (VSX) and Aruba's Virtual Switching Framework (VSF). This course is approximately 50% lecture and 50% hands-on lab exercises.
