ntroller. DHCP Option 63 and 43 is used for discovery. Management of the devices with PnP is through the login to the APIC EM Controller and click on Network Plug and Play at the left hand side of the Dashboard. Easy QoS APIC-EM can configure end-to-end QoS by providing the Cisco validated design features SO that the provisioning & configuring QOS can be reduced from weeks to minutes without any human error or Involvement. One of the options to configure the QOS end to end is with APIC-EM to categorize the applications as Business Relevant, Business Irrelevant and Default. QOS best practices are used to generate specific Network configuration The other option is with the help of REST Application programming Interface. How Easily Does QOS Work? Network Administrator initiated the intent to APIC EM QOS, the applications are continuously interacting with APIC EM-SDN Controller for Enterprise through northbound APIs and convey the application specific requirements and dynamic QOS requirements to the Controller (APIC EM). Southbound application programming Interfaces converts the application/ platform dynamic QOS requirements to specific platform configuration to the existing Infrastructure.

APIC-EM is built in with Cisco best practices for hybrid WAN leads to software defined WAN. Using Cisco IWAN provides greater bandwidth to the branch office without using the expensive hardware and maintaining the security and efficiency at the same time. The two proposed primary IWAN Models are Dual Internet & Hybrid Deployment. IWAN is Software Defined WAN of Cisco which uses combination of two technologies DMVPN and PFR. DMVPN Dynamic Multipoint VPN is a solution for
