7.3.2 Configuring the STP/RSTP Mode
Before configuring basic STP/RSTP functions on a switching device, set the working mode to
STP or RSTP. RSTP is compatible with STP.
Procedure
Step 1
Run:
system-view
The system view is displayed.
Step 2
Run:
stp mode
{
stp
|
rstp
}
The working mode of the switching device is set to STP or RSTP.
By default, the working mode of a switching device is MSTP. MSTP is compatible with STP
and RSTP.
On a ring network running only STP, set the working mode of a switching device to STP; on a
ring network running RSTP, set the working mode of a switching device to RSTP. In other cases,
use the default working mode MSTP.

7.3.3 (Optional) Configuring Switching Device Priorities
Select a switching device (functioning as a root bridge) from switching devices for each spanning
tree. You can configure the priorities of the switching devices to preferentially select a root
bridge. The lower the numerical value is, the higher priority a switching device has and the more
likely the switching device will be selected as a root bridge.
Context
On an STP/RSTP-capable network, there is only one root bridge, which is the logic center of
the entire spanning tree. During root bridge selection, a high-performance switching device at
a high network layer should be selected as the root bridge; however, the priority of such a device
may not be the highest on the network. It is therefore necessary to set a high priority for the
switching device to ensure that the device functions as a root bridge.
Low-performance devices at lower network layers are not fit to serve as a root bridge. Therefore,
set low priorities for these devices.
