Example
This example shows how to enable the Spanning Tree Algorithm for the
switch:
spanning-tree mode
This command selects the spanning tree mode for this switch. Use the no
form to restore the default.
Syntax
spanning-tree mode {stp | rstp}
no spanning-tree mode
• stp - Spanning Tree Protocol (IEEE 802.1D)
• rstp - Rapid Spanning Tree Protocol (IEEE 802.1w)
Default Setting
rstp
Command Mode
Global Configuration
Command Usage
• Spanning Tree Protocol
Uses RSTP for the internal state machine, but sends only 802.1D
BPDUs.
• Rapid Spanning Tree Protocol
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 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.
