After one of the configurations described before is changed, there are buttons that
allows the user to save or discard the configurations.
Save: save configuration at the Running Config;

Reset: undo changes made locally at the Running Config.

MSTI Ports:
MSTI Ports Settings menu allows configuring CIST parameters to each MSTI instance.
A given port can operate as a CIST port for many MSTI instances, if this port belongs
to more than one region. Thus, it can operate in forwarding state in a given MSTI
instance and in blocking state for another MSTI. MSTI menu allows the user to
configure each MSTI instance of the switch.
By default it will appear the Select MSTI field at this menu. MSTI field has a list of all
MSTI regions allowed to be created in Reason Switches. Select the desired MSTI
instance and then press Get button. When Get button is pressed, it will appear the
MSTI Aggregated Ports Configuration and the MSTI Normal Ports Configuration
tables.
If one configuration is desired to be applied at all instances, then the row "*" should
be used, that is, configuration done in the "*" row will be replied to all instances.
Possible configurations are as follows.
MSTI Aggregated Ports Configuration
o

BPDU Guard: enable the port to operate in BPDU Guard
mode. This function causes the port to disable itself if a
BPDU message is received in that port, as could happens
if a non-STP bridge is looped in the Spanning Tree
network. Ports operating as Edge ports are not affected
by this setting. Checkbox selected means that the port will
disable itself if a BPDU packet is received, and checkbox
empty means port will not disable itself in that case;
Point-to-point: indicates if port is connected to a
switched full-duplex LAN (point-to-point LAN) or a shared
medium LAN. Allowed values are Auto, Forced True and
Forced False. Auto selection means that switch will detect
automatically if full-duplex operation is allowed or not,
forced true means port will always operate as Point-to-
point connection and forced false means port will always
be considered as a shared medium. Point-to-point
connections have a transition to forward state faster than
shared medium LAN connection.
Port: shows the aggregated ports to be configured at this
row;
