Parameter
interface-list: Ethernet port list, containing multiple Ethernet ports and expressed
as interface-list = { interface-type interface-number [ to interface-type
interface-number ] }&<1-10>. For detail descriptions of interface-type and
interface-number 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: Maximum number of configuration BPDUs that can be transmitted via
the port per Hello Time, 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 transmit-limit command to configure an amount limit to
the configuration BPDU transmitted via a specified port during the Hello Time in
system view.
Use the undo stp interface transmit-limit command to restore the default limit
on the specified port 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.
