edge safeguard
    Loop prevention and
        detection on an edge port configured for 
RSTP (Rapid Spanning Tree Protocol). Configuring edge
        safeguard on RSTP edge ports can prevent accidental or deliberate misconfigurations (loops)
        resulting from connecting two edge ports together or from connecting a hub or other
            non-
STP (Spanning Tree Protocol) switch to an edge port. Edge safeguard also limits
        the impact of broadcast storms that might occur on edge ports. This advanced loop prevention
        mechanism improves network resiliency but does not interfere with the rapid convergence of
        edge ports.
