TCN Filter
Select to enable or disable the TCN filter option. Enabling TCN filtering
on a port is useful for connecting to an external network, which may not
be under full control of the administrator. When a port is set to the TCN
filter mode, the topology change event received by the port will be
ignored. By default, this option is disabled.
BPDU Forward
Bridges use Bridge Protocol Data Units (BPDUs) in the operation of
spanning tree, BPDU. Forwarding is useful when a bridge
interconnects two regions, with each region requiring a separate
spanning tree. BPDU filtering functions only when STP is disabled
either globally or on a single interface. The possible field values are:

Disabled: BPDU filtering is enabled on the port.

Enabled: BPDU forwarding is enabled on the port (STP must be
disabled).
Priority
Select the priority of each port. Selectable range is from 0 to 240, and
the default setting is 128. The lower the number, the greater the
probability the port will be chosen as a root port.
Hello Time
The interval between two transmissions of BPDU packets sent by the
Root Bridge to indicate to all other switches that it is indeed the Root
Bridge. The default value is 2.

L2 Features > STP > MST Configuration Identification
Multiple Spanning Tree (MSTP) provides various load balancing scenarios by allowing multiple VLANs to be
mapped to a single spanning tree instance, providing multiple pathways across the network. For example,
while port A is blocked in one STP instance, the same port can be placed in the Forwarding state in another
STP instance.
The MST Configuration Identification page is for defining global MSTP settings, including region names,
MSTP revision level.
