The larger the value is, the more packets can be transmitted in a time unit, yet the more
switch resources will be occupied. With a moderate value, the amount of the BPDUs
transmitted during Hello Time via every port can be limited and MSTP will not occupy
too many bandwidth resources when the network topology flaps.
Related command: stp transmit-limit.
Example
# Set a limit of 5 to the packets transmitted via Ethernet2/1/3 in system view.
<Quidway>system-view
System View: return to User View with Ctrl+Z.

Syntax

Parameter

Description
Use the stp loop-protection command to enable loop protection function.
Use the undo stp loop-protection command to restore the default setting.
By default, the loop protection function is not enabled.
 Note:
The port configured with loop protection can only turn into discarding state on every
instance. When such port receives no configuration message for a long time, only the
port role changes, its discarding state remains unchanged, so no packets are
forwarded. In this way, if the peer end cannot send BPDU packets due to error
operation, and the port enters forwarding state directly for not receiving configuration
message for a long time, no loop will be generated by enabling the loop protection.
