Description
Select the protocol version. There are three types selectable:
 STP: The most basic spanning tree protocol.
 RSTP: Improved based on STP, and realizes rapid convergence.
 MSTP: Remedies the defects of STP and RSTP. MSTP not only
realizes rapid convergence, but also provides better load sharing
mechanism for the redundant links by forwarding the flow from
different VLANs through there own paths.
Set the bridge priority. The smaller the value is, the higher the priority
level is. And the value of bridge priority should be the multiple of 4096.
Set the period for sending packet.
Set the delay time of the port forwarding.
Set the Maximum life cycle that the packet can be saved in the device.
Set the Maximum hop count for MST domain, and it decides the scale
of the MST domain.
Only the Maximum hop count configured in the domain root takes
effect in the domain. Otherwise the parameter is invalid.
Set the Maximum number of times that the address table is updated
and forwarded in a period of time after the TC-BPDU packet is
