Cisco Plug and Play

Cisco Plug and Play (PnP) allows for highly secure, scalable, seamless, and unified zero-touch provisioning of network devices. This allows you to simply unbox a brand new switch plug it in and power it on. Cisco DNA Center will provision the configuration of the switch as well as update firmware for you automatically. You no longer need to pre-stage equipment by manually copying and pasting config or uploading the correct firmware before you rack and stack. This can save you a lot of time as well as make your job a whole lot easier while incurring major operating costs.

The Cisco Plug and Play (PnP) deployment includes a PnP agent, a PnP server, and other components. The Cisco Plug and Play (PnP) agent is an embedded software component that is present in all Cisco network devices that support simplified deployment architecture. After the configuring the uplink switch ports, by default, the new switch will attempt to connect to the PnP server on VLAN 1 to communicate with DNA Center. For this mater, first, the new switch will need to know how to locate the DNA Center server. It can use DNA with an A record pointing to PnP server, your domain DHCP option 43 or even the cloud to find the IP address of DNA Center.

Plug and Play

New Cisco devices are shipped to customers with no startup configuration file in the NVRAM of the devices are starting auto install plug and play zero touch provisioning.

Plug and Play licenses are also essential for Cisco SDWAN solution. Customers should add their PnP licenses on the Cisco vManage in order to provision their vEdge devices in their SDWAN environment.

Note: It is important that we do not enter anything at the initial configuration prompt because that will halt the PnP process.

Note: if you would like to run PnP on an existing switch or one that has already been configured, you have to perform some device cleanup. You would have to remove the PnP profile, any certificates on the switch, VLANs and the startup config. Also, you need your DNA Center fully configured.
