DES-3500 Series Layer 2 Stackable Fast Ethernet Managed Switch User Manual
is globally enabled (See STP Bridge Global Settings above).
hw_filtering is an option that is only required by some legacy chipsets, which cannot support
per L2 protocol packet control. When the state is set to hw_filtering, if STP BPDU is received
by this port, the port will be changed to BPDU hardware filtering mode such that all layer 2
control packets will be dropped by the hardware.
The default setting False, does not forward BPDU packets when STP is disabled.
This drop-down menu allows you to enable or disable STP for the selected group of ports. The
default is Enabled.
When a port is in BPDU hardware filtering mode, it can be recovered by this option.
