CONFIGURING THE SWITCH
STP Configuration
Global settings apply to the entire switch.
Command Usage
RSTP supports connections to either STP or RSTP nodes by monitoring the incoming protocol messages and dynamically adjusting the type of protocol messages the RSTP node transmits, as described below:
•STP Mode – If the switch receives an 802.1D BPDU (i.e., STP BPDU) after a port’s migration delay timer expires, the switch assumes it is connected to an 802.1D bridge and starts using only 802.1D BPDUs.
•RSTP Mode – If RSTP is using 802.1D BPDUs on a port and receives an RSTP BPDU after the migration delay expires, RSTP restarts the migration delay timer and begins using RSTP BPDUs on that port.
Command Attributes
•Spanning Tree State — Enables or disables the Spanning Tree. If you enable the Spanning Tree, you must complete the other fields. (Default: enabled)
•Spanning Tree Type — Specifies the type of Spanning Tree Protocol used on the switch: (Default: RSTP)
•STP: Spanning Tree Protocol (IEEE 802.1D; i.e., when this option is selected, the switch will use RSTP set to STP forced compatibility mode))
•RSTP: Rapid Spanning Tree (IEEE 802.1w)
•Priority — Bridge priority is used in selecting the root device, root port, and designated port. The device with the highest priority becomes the STP root device. However, if all devices have the same
