Select the BPDU Filter Disable or Enable radio button.
12.
This specifies whether the BPDU Filter feature is enabled. STP BPDU filtering applies to
all operational edge ports. Edge Port in an operational state is supposed to be connected
to hosts that typically drop BPDUs. If an operational edge port receives a BPDU, it
immediately loses its operational status. In that case, if BPDU filtering is enabled on this
port then it drops the BPDUs received on this port.
Select the Fast Backbone Mode Disable or Enable radio button. (PVSTP only.)
13.
Use this option to choose a new indirect link when an indirect link fails. The system does
not ignore inferior BPDUs, as is done in 802.1d. Rather the system uses the BPDUs to
age out on the port it received the BPDUs. Later the system sends out root link queries on
other non-designated ports. Based on the replies, if there is a positive response to at
least one of them, it chooses a new indirect link. Fast Backbone mode is disabled by
default.
Select the Fast Uplink Mode Disable or Enable radio button. (PVSTP only.)
14.
This option reduces the recovery time in selecting a new root port when the primary root
port goes down. Fast Uplink mode is disabled by default.
Use the Max Update Rate field to configure the Fast Uplink Maximum Update Rate.

This field is enabled for configuration when Fast Uplink mode is enabled. Allowed values
are 0 to 32000 packets per second. The default value is 150.
