Management
Cisco Business DashboardSupport for embedded probe for Cisco Business Dashboard running on the switch. Eliminates the need to set up a separate hardware or virtual machine for the Cisco Business Dashboard probe onsite
Cisco Business mobile appMobile app for Cisco Business switch and wireless products. Helps to set up a local network in minutes and provide easy management at your fingertips.
Cisco Network Plug and Play (PnP) agent

The Cisco Network PnP solution provides a simple, secure, unified, and integrated offering to ease new branch or campus device rollouts or for provisioning updates to an existing network. The solution provides a unified approach to provision Cisco routers, switches, and wireless devices with a near-zero-touch deployment experience.

Supports Cisco PnP Connect
