ARAMETERS
These parameters are displayed on the MSTP Edit MSTI/ VLAN page:

Port – The Port identity of switch physical interface. Port number is
1 to 24.

Path Cost - The same definition as in the RSTP specification. But in
MSTP, this parameter can be respectively applied to ports of CIST
and ports of any MSTI. Range is 1 to 200,000,000.

Priority - The same definition as in the RSTP specification. But in
MSTP, this parameter can be respectively applied to ports of CIST
and ports of any MSTI. The available value: 0 / 16 / 32 / 48 / 64 /
80 / 96 / 112 / 128 / 144 / 160 / 176 / 192 / 208 / 224 / 240.

Hello Time - In contrast with RSTP, Hello Time in MSTP is a per
port setting for the CIST. The available value: 1 / 2.

Admin Edge - The same definition as in the RSTP specification for
the CIST ports. The available value: Yes / No.

Admin P2P - The same definition as in the RSTP specification for
the CIST ports. The available value: Auto / True / False.

Restricted Role - If ―Yes‖ causes the Port not to be selected as
Root Port for the CIST or any MSTI, even it has the best spanning
tree priority vector. Such a Port will be selected as an Alternate Port
after the Root Port has been selected. This parameter is ―No‖ by
default. If set, it can cause lack of spanning tree connectivity. It is
set by a network administrator to prevent bridges external to a core
region of the network influencing the spanning tree active topology,
possibly because those bridges are not under the full control of the
administrator. The available value: Yes / No.

Restricted TCN - If ―Yes‖ causes the Port not to propagate
received topology change notifications and topology changes to
other Ports. This parameter is ―No‖ by default. If set it can cause
temporary loss of connectivity after changes in a spanning trees
active topology as a result of persistent incorrectly learned station
location information. It is set by a network administrator to prevent
bridges external to a core region of the network, causing address
flushing in that region, possibly because those bridges are not under
the full control of the administrator. or the status of MAC operation
for the attached LANs transitions frequently. The available value:
Yes / No.

Mcheck - The same definition as in the RSTP specification for the
CIST ports.
