Protocols and Standards

MSTP is documented in:
IEEE 802.1D: spanning tree protocol
IEEE 802.1w: rapid spanning tree protocol
IEEE 802.1s: multiple spanning tree protocol

MSTP Configuration Task List

Before configuring MSTP, you need to know the position of each device in each MSTI: root bridge or
leave node. In each MSTI, one, and only one device acts as the root bridge, while all others as leaf
nodes.
Complete these tasks to configure MSTP:
Configuring
Enabling MSTP
Root Bridge
Configuring an MST Region
Specifying the Current Switch as a Root
Bridge/Secondary Root Bridge
Configuring the Bridge Priority of the
Current Switch
Configuring How a Port Recognizes and
Sends MSTP Packets
Configuring the MSTP Operation Mode
Configuring the Maximum Hop Count of an
MST Region
Configuring the Network Diameter of the
Switched Network
Configuring the MSTP Time-related
Parameters
Configuring the Timeout Time Factor
Task
1-15
Remarks
Required
To prevent network topology jitter
caused by other related configurations,
you are recommended to enable MSTP
after other related configurations are
performed.
