NOTE
If the current device supports MSTP, configuring MSTP is recommended.
Pre-configuration Tasks
Before configuring basic MSTP functions, complete the following task:
l Connecting interfaces and setting physical parameters for the interfaces to ensure that the
physical status of the interfaces is Up
l Configuring VLAN features of the ports
NOTE
After a hybrid interface is added to the default VLAN in tagged mode, SEP packets sent by the
interface contain VLAN tags. In this case, configure the peer interface to allow packets of the default
VLAN to pass.
Data Preparation
To configure basic MSTP functions, you need the following data.
No. Data
1 MSTP working mode
2 MST region name, VLAN-to-instance mapping, and MSTP revision number
3 (Optional) ID of an MSTI
4 (Optional) Priority of a switching device in an MSTI
5 (Optional) Priority of a port in an MSTI
6 (Optional) Path cost of a port in an MSTI
9.2.2 Configuring the MSTP Mode
Before configuring basic MSTP functions, you need to configure the working mode of a
switching device to MSTP. MSTP is compatible with STP and RSTP.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
stp mode mstp
The working mode of the switching device is configured as MSTP. By default, the working
mode is MSTP.
STP and MSTP cannot recognize packets of each other but MSTP and RSTP can. If a switching
device is configured to work in MSTP mode and is connected to some switching devices running
STP, the switching device automatically transits the working mode of the interfaces connected
