Implementation of MSTP on devices
MSTP is compatible with STP and RSTP. STP and RSTP protocol packets can be recognized by devices
running MSTP and used for spanning tree calculation.
In addition to basic MSTP functions, the device provides the following functions for ease of management:
•
Root bridge hold
Root bridge backup
•
•
Root guard
BPDU guard
•
Loop guard
•
•
TC-BPDU (a message that notifies the device of topology changes) guard
Protocols and standards
IEEE 802.1d, Spanning Tree Protocol
•
•
IEEE 802.1w, Rapid Spanning Tree Protocol
IEEE 802.1s, Multiple Spanning Tree Protocol
•
Recommended MSTP configuration procedure
Step
1. Configuring an MST region
2. Configuring MSTP globally
3. Configuring MSTP on a port
4. Displaying
information of a port
Configuring an MST region
Select Network > MSTP from the navigation tree.
1.
By default, the Region tab is displayed.
Remarks
(Optional.)
Configure the MST region-related parameters and VLAN-to-MSTI mappings.
By default, the MST region-related parameters adopt the default values, and
all VLANs in an MST region are mapped to MSTI 0.
(Required.)
Enable STP globally and configure MSTP parameters.
Whether STP is enabled globally depends on the device model; all MSTP
parameters have default values.
(Optional.)
Enable MSTP on a port and configure MSTP parameters.
By default, MSTP is enabled on a port, and all MSTP parameters adopt the
default values.
(Optional.)
MSTP
Display MSTP information of a port in MSTI 0, the MSTI to which the port
belongs, and the path cost and priority of the port.
