Implementation Of Mstp On Devices; Protocols And Standards; Mstp Configuration Task List - HP A5120 EI Series Configuration Manual

Implementation of MSTP on devices

MSTP is compatible with STP and RSTP. Devices that are running MSTP and that are used for spanning
tree calculation can identify STP and RSTP protocol packets.
In addition to basic MSTP functions, the following functions are provided for ease of management:
Root bridge hold

Root bridge backup

Root guard

BPDU guard

Loop guard

TC-BPDU guard

BPDU drop


Protocols and standards

MSTP is documented in the following protocols and standards:
IEEE 802.1d: Media Access Control (MAC) Bridges

IEEE 802.1w: Part 3: Media Access Control (MAC) Bridges—Amendment 2: Rapid Reconfiguration

IEEE 802.1s: Virtual Bridged Local Area Networks—Amendment 3: Multiple Spanning Trees


MSTP configuration task list

Before configuring MSTP, you must plan the role of each device in each MSTI, root bridge or leaf node,
and then configure the devices as planned. In each MSTI, only one device acts as the root bridge, and all
others act as leaf nodes.
Complete these tasks to configure MSTP:
Task
Configuring the root
bridge
Configuring an MST region
Configuring the root bridge or a secondary root bridge
Configuring the work mode of an MSTP device
Configuring the priority of a device
Configuring the maximum hops of an MST region
Configuring the network diameter of a switched network
Configuring timers of MSTP
Configuring the timeout factor
Configuring the maximum port rate
Configuring ports as edge ports
Configuring the link type of ports
Configuring the mode a port uses to recognize/send MSTP
