Port roles in rstp
WebMar 14, 2016 · When a port comes up is when STP or RSTP will take notice of it and perform the proper STP calculations on it, assigning a state to the port. Some documentation assigns such a port a state of "Disabled," but that is a port role rather than an STP state. WebThere are only three port states left in RSTP that correspond to the three possible operational states. The 802.1D disabled, blocking, and listening states are merged into a unique 802.1w discarding state. STP (802.1D) Port State RSTP (802.1w) Port State Is Port Included in Active Topology? Is Port Learning MAC Addresses? Disabled Discarding No No

WebThe same spanning tree algorithm is used for both STP and RSTP to determine port roles and topology. RSTP increases the speed of the recalculation of the spanning tree when the Layer 2 network topology changes. RSTP can achieve much faster convergence in a properly configured network, sometimes in as little as a few hundred milliseconds. WebThe RSTP port interface is designated as point-to-point, by default, in the existing port configuration screen. The following procedure configures RSTP: In the Mobility Conductor node hierarchy, navigate to the Configuration > Interfaces > Ports tab. In the Ports table, click the port number for which you want to enable RSTP or STP features.
