[forward-time <value> | hello-time <value> | max-age <value> | priority <value> | vlan
range <WORD>
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 spanning-tree (Configuration Interface) for details on the RSTP (config-if) command.
Syntax
Parameter Description Range Default
forward-time
Specifies the time, in seconds, the port
spends in the listening and learning state.
During this time, the port waits to forward
data packets.
4-30 15 seconds
hello-time
Specifies the time, in seconds, between each
bridge protocol data unit (BPDU) transmitted
by the root bridge.
1-10 2 seconds
max-age
Specifies the time, in seconds, the root bridge
waits to receive a hello packet before
changing the STP topology.
6-40 20 seconds

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

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 command to disable RSTP.
