Huawei quidway s7700 - Configuring the STP;RSTP Mode; Optional) Configuring Switching Device Priorities

No. Data
1 (Optional) Priority of a switching device
2 (Optional) Priority of a port
3 (Optional) Path cost of a port
8.2.2 Configuring the STP/RSTP Mode
Before configuring basic STP/RSTP functions, you need to configure the working mode of a
switching device to STP/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 configured as STP/RSTP.
By default, the working mode of the S7700 is MSTP.

8.2.3 (Optional) Configuring Switching Device Priorities
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 and it is the logic center of the
entire spanning tree. In root bridge selection, the switching device with high performance and
network hierarchy is generally selected as a root bridge; however, the priority of such a device
may be not that high. Thus setting a high priority for the switching device is necessary so that
the device can function as a root bridge.
Other devices with low performance and network hierarchy are not fit to be a root bridge.
Therefore, set low priorities for these devices.
CAUTION
If an S7700 is configured as the root switch or secondary root switch, the priority of the
S7700 cannot be set. If you want to set the priority of the S7700, you must disable the root switch
or secondary root switch.
