Setting The Maximum Transmission Rate Of An Interface - Huawei AR530 series Configuration Manual

Huawei AR530&AR550 Series Industrial Switch Routers
Configuration Guide - Ethernet Switching
l If the Ethernet interface works in full-duplex mode, the interface is connected to a P2P link.
l If the Ethernet interface works in half-duplex mode, you can run the stp point-to-point

6.6.3.6 Setting the Maximum Transmission Rate of an Interface

Context
The more BPDUs sent from an interface within a Hello Time interval, the more system resources
consumed. Setting a proper transmission rate (packet-number) on an interface prevents excess
bandwidth usage when network flapping occurs.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The view of an Ethernet interface participating in STP calculation is displayed.
Step 3 Run:
stp transmit-limit packet-number
The maximum transmission rate of BPDUs (BPDUs per second) is set for the interface.
By default, an interface sends a maximum of six BPDUs per second.

6.6.3.7 Switching to the RSTP Mode
Context
If an interface on an RSTP-enabled device is connected to an STP-enabled device, the interface
switches to the STP compatible mode.
If the STP-enabled device is powered off or disconnected from the RSTP-enabled device, the
interface cannot switch back to the RSTP mode. In this case, run the stp mcheck command to
switch the interface to the RSTP mode.
You need to manually switch the interface to the RSTP mode in the following situations:
Issue 01 (2014-11-30)
In this case, force-true can be specified in the command to implement rapid network
convergence.
force-true command to forcibly set the link type to P2P.
NOTE
If the same maximum transmission rate of BPDUs needs to be sent for each interface on a device, run the
stp transmit-limit (system view) command.
