Recognition Display RSTP Convergence Test for Fast Link Recovery
A school recognition display RSTP convergence test verifies that Rapid Spanning Tree Protocol (IEEE 802.1w) reconfigures your managed-switch topology quickly enough after an uplink failure that a lobby kiosk or hall-of-fame touchscreen reconnects to the network within seconds rather than sitting offline for half a minute or more. RSTP convergence is the process by which switches in a network with redundant paths detect a failed link, elect a new active path, and transition the relevant ports from Discarding through Learning to Forwarding—restoring normal traffic flow. When RSTP is correctly configured, convergence completes in one to six seconds. When it is misconfigured or a switch is running classic STP (802.1D) rather than RSTP, the same failover can take thirty to fifty seconds—long enough for an uplink failure during an awards ceremony or induction night to produce a visible content outage on the recognition display.
