False - This switch can only operate with RSTP and MSTP
packets.
The net effect of setting all ports on the switch to True is that it
forces the switch into the role of the root bridge regardless of other
path costs in the network.
Restricted TCN - The Restricted TCN parameter does not allow
Topology Change Notification (TCN) BPDUs to be processed on
the port.
True - The port cannot process receive/transmit TCN BPDUs.
False - The port can process receive/transmit TCN BPDU
packets.
Migrate - A switch running MSTP supports a built-in protocol
migration mechanism that enables it to inter-operate with legacy
802.1D switches. Clicking the Restart button under the Migrate
field in the All row restarts the protocol migration process for all
ports on the switch. Clicking the Restart button under the Migrate
field for a specific port restarts the protocol migration process for
that port only.
4. Once you have configured the parameters, click Apply in the Action

5. If you choose to change the MSTP port configuration for other ports,
repeat Step 3 and Step 4.
6. From the main menu on the left side of the page, select Save Settings
