Defining Rapid Spanning Tree

While Classic STP prevents Layer 2 forwarding loops in a general network topology,
convergence can take between 30-60 seconds. This time may delay detecting
possible loops and propagating status topology changes. Rapid Spanning Tree
Protocol (RSTP) detects and uses network topologies that allow a faster STP
convergence without creating forwarding loops. The Global System LAG information
displays the same field information as the ports, but represent the LAG RSTP
information. The RSTP Page contains parameters for defining RSTP.
Command Attributes
• Interface — Displays the interfaces on which RSTP is enabled. The possible field
values are:
• All Ports — Enables RSTP on all ports.
• All LAGs — Enables RSTP on all LAGs.
• Interface — Displays the port or LAG on which Rapid STP is enabled.
• Role — Displays the port role assigned by the STP algorithm to provide to STP
paths. The possible field values are:
