Operation Manual – MSTP
H3C S7500E Series Ethernet Switches Chapter 1 MSTP Configuration
1-18
In addition to basic MSTP functions, many management-facilitating special functions
are provided, as follows:
z Root bridge hold
z Root bridge backup
z Root guard
z BPDU guard
z Loop guard
z TC-BPDU guard
1.1.3 Protocols and Standards
MSTP is documented in:
z IEEE 802.1d: Spanning Tree Protocol
z IEEE 802.1w: Rapid Spanning Tree Protocol
z IEEE 802.1s: Multiple Spanning Tree Protocol
1.2 Configuration Task List
Before configuring MSTP, you need to know the position of each device in each MST
instance: root bridge or leave node. In each instance, one, and only one device acts as
the root bridge, while all others as leaf nodes.
Complete these tasks to configure MSTP:
