NOTE: RSTP is backward compatible with STP and is enabled by default. For ease of use, this command uses the spanning tree
keyword.
Description
This command is the global configuration for the Rapid Spanning Tree Protocol (RSTP) and Per VLAN Spanning
Tree (PVST+). See

Usage Guidelines
This command configures the global RSTP settings on the controller and is backward compatible with past versions
of ArubaOS using STP.
By default, all interfaces and ports on the controller run RSTP as specified in 802.1w and 802.1D. The default RSTP
values can be used for most implementations.
Use the
no spanning-tree
Examples
The following command sets the time a port spends in the listening and learning state to 3 seconds:

spanning-tree (Configuration Interface)
Description
Specifies the time, in seconds, the port spends in
the listening and learning state. During this time, the
port waits to forward data packets.
Specifies the time, in seconds, between each
bridge protocol data unit (BPDU) transmitted by the
root bridge.
Specifies the time, in seconds, the root bridge waits
to receive a hello packet before changing the STP
topology.
Set the priority of a bridge to make it more or less
likely to become the root bridge. The bridge with the
lowest value has the highest priority.
When configuring the priority, remember the
following:
The highest priority bridge is the root bridge.
The highest priority value is 0 (zero).
Enter the keywords vlan range followed by the
range of VLAN iID's. Separate the VLAN IDs with a
hyphen, comma or both to indicate the range.
For example: 2-3 or 2,4,6 or 2-6,11
command to disable RSTP.
