Root Guard Definition: Root Guard is a feature in Cisco's Spanning Tree Protocol that prevents a port from becoming a root port if a superior BPDU is received.
Root Guard is a feature in network security that prevents a network device, like a switch, from becoming the root bridge in a Spanning Tree Protocol (STP) topology. It ensures that the device with Root Guard enabled does not participate in the election process for the root bridge, thus protecting the integrity of the network topology and preventing unauthorized devices from gaining control over the network.
