10.2.0E or later
spanning-tree mode rstp
Enables an STP type: RSTP.
Syntax
spanning-tree mode rstp
Parameters
● rstp — Sets STP mode to RSTP.
Default Rapid-PVST
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
OS10(config)# spanning-tree mode rstp
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 to operate in an STP-compatible manner to avoid frame mis-ordering 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
