e upgraded. Task would take at least a week to get this done manually on every router, switch, Wireless Access Point Plug & Play (PnP) Application of Cisco APIC-EM will reduce the time to configure the above task from a week to hours by uploading the Image & the base configuration to APIC-EM & pushing this configuration to the network devices with PnP Server and agent communication. Network Plug and Play is fast, consistent and secure method of device management. This gives us the leverage for Zero touch deployment and provisioning of the enterprise Infrastructure. It uses secure HTTPS method to manage the network and push configurations and manages the network throughout for Routers, Switches, Access Points Etc. Administrator gets the visibility to continuously monitor the progress of the Installation, configurations, status Etc. Network Plug n Play can be used for both Greenfield and Brownfield deployments. It uses a very simple Agent-Server communication concept for deployment.

Agent is embedded in IOS and it requests for IP and APIC EM address which it gets via DHCP. Communication is completely secure as it operates over https/tcp. PnP Server runs on the controller - APIC-EM which is the centralized server for the entire enterprise Infrastructure. It manages the configuration files, Images files, devices licenses Etc. PnP is the protocol that runs between the PnP agent and PnP Server. APIC EM is the controller which is communicating to the end Cisco devices like Catalyst switches, ASR, ISR, Access Points etc with southbound APIs like CLI, PnP Protocol, SNMP etc. APIC EM northbound APIs can be used by the third party apps to manage APIC EM controller. Codes in programming languages like python, JSON can be used to manage the end network and communicate to the co
