Connectivity Guide

spanning-tree mode
Enables an STP type: RSTP, Rapid-PVST+, or MST.
Syntax
spanning-tree mode {rstp | mst | rapid-pvst}
Parameters
● rstp — Sets STP mode to RSTP.
● mst — Sets STP mode to MST.
● rapid-pvst — Sets STP mode to RPVST+.
Default RPVST+
Command Mode CONFIGURATION
Usage
Information
All STP instances stop in the previous STP mode, and restart in the new mode. You can also change to
RSTP/MST mode.
Example (RSTP)
OS10(config)# spanning-tree mode rstp
Example (MST)
OS10(config)# spanning-tree mode mst
Supported
Releases
10.2.0E or later
spanning-tree port
Sets the port type as the EdgePort.
Syntax
spanning-tree port type edge
Parameters None
Default Not configured
Command Mode INTERFACE
Usage
Information
When you configure an EdgePort on a device running STP, the port immediately transitions to the
Forwarding state. Only configured ports connected to end hosts act as EdgePorts.
Example
OS10(config)# spanning-tree port type edge
Supported
Releases
10.2.0E or later
spanning-tree rstp force-version
Configures a forced version of spanning tree to transmit BPDUs.
Syntax
spanning-tree rstp force-version stp
Parameters stp — Force the version for the BPDUs transmitted by RSTP.
Default Not configured
Command Mode CONFIGURATION
Usage
Information
Forces a bridge that supports RSTP or MST to operate in a STP-compatible manner to avoid frame
misordering and duplication in known LAN protocols that are sensitive.
Example
OS10(config)# spanning-tree rstp force-version stp
Supported
Releases
10.2.0E or later
