Disabling Bpdu Packets From Flooding In The Default Vlans - H3C S9500 Series Operation Manual

Operation Manual – MSTP
H3C S9500 Series Routing Switches
Note that, disabling MSTP on Ethernet ports may result in redundant paths.
MSTP can be enabled/disabled on a port through the following ways.
Configuration in system view

By default, MSTP is enabled on all the ports after it is enabled on the device.

1.2.19 Disabling BPDU Packets from Flooding in the Default VLANs

If STP (spanning tree protocol) is not enabled, or if STP is disabled on a port though it is
enabled globally, the BPDU packets through the STP-disabled port will be broadcast in
the default VLAN, and these BPDU packets will affect the STP operation on other ports.
The stp non-flooding command can discard the BPDU packets entering the
STP-disabled port of the interface card, and thus prohibiting the BPDU packets from
being broadcast in the VLAN.
