Loop guard
TC-BPDU (a message that notifies the device of topology changes) guard
Support for the hot swapping of interface boards and switchover of the active and standby main
boards.
IEEE 802.1d, Spanning Tree Protocol
IEEE 802.1w, Rapid Spanning Tree Protocol
IEEE 802.1s, Multiple Spanning Tree Protocol
Two or more spanning tree devices belong to the same MST region only if they are configured to
have the same MST region name, MST region level, and the same VLAN-to-instance mapping
entries in the MST region, and they are connected through a physical link.
If two or more devices are selected as the root bridge in a spanning tree at the same time, the device
with the lowest MAC address is chosen.
If BPDU guard is disabled, a port set as an edge port becomes a non-edge port again if it receives
a BPDU from another port. To restore its port role as an edge port, you must restart the port.
If a port directly connects to a user terminal, configure it as an edge port and enable BPDU guard
for it. This enables the port to quickly transit to the forwarding state when ensuring network security.
Step
1. Configuring an MST
region.
2. Configuring MSTP globally.
3. Configuring MSTP on a
port.

Remarks
Optional.
Configure the MST region-related parameters and VLAN-to-instance
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.
By default, STP is enabled globally. 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.
