Example

Parameter
interface-list: Ethernet port list, containing multiple Ethernet ports and
expressed as
interface _list = { { interface_type interface_num |
interface_name } [ to { interface_type interface_num | interface_name } ]
}&<1-10>. For detail descriptions of
interface_type, interface_num and
interface_name parameters, refer to the corresponding descriptions in Port
Command Manual. &<1-10> means that the preceding parameters can be
entered up to 10 times.
packetnum: Specifies the amount limit to the transmitted packets, ranging from 1
to 255 (expressed as a counter value without any units). By default, the
transmission limit on every port is 3.
Description
■ Use the stp interface transit-limit command to configure an amount
limit to the configuration BPDU transmitted via a port during the Hello Time in
system view.
■ Use the undo stp interface transit-limit command to restore the default
limit in system view.
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 transit-limit.
Example
Set a limit of 5 to the packets transmitted via Ethernet5/0/3 in system view.
