Define an Instance Index using the spinner control and then set the cost. The default path cost depends on the
user defined port speed.The cost helps determine the role of the port channel in the MSTP network. The
designated cost is the cost for a packet to travel from this port to the root in the MSTP configuration. The slower
the media, the higher the cost.

MSTP Configuration
Select the check box to define this port as an edge port. Using an edge
(private) port, you can isolate devices to prevent connectivity over this port
channel. This setting is disabled by default.
Select either the Point-to-Point or Shared radio button. Selecting
Point-to-Point indicates the port should be treated as connected to a
point-to-point link. Selecting Shared means this port should be treated as
having a shared connection. A port connected to a hub is on a shared link,
while one connected to a access point is a point-to-point link. Point-to-Point
is the default setting.
Select either the Enable or Disable radio buttons. This enables
interoperability with Cisco's version of MSTP, which is incompatible with
standard MSTP. This setting is disabled by default.
Sets the protocol version to either STP(0), Not Supported(1), RSTP(2) or
MSTP(3). MSTP is the default setting.
Determines whether the port channel enforces root bridge placement.
Setting the guard to Root ensures the port is a designated port. Typically,
each guard root port is a designated port, unless two or more ports (within
the root bridge) are connected together. If the bridge receives superior
(BPDUs) on a guard root-enabled port, the guard root moves the port to a
root-inconsistent STP state. This state is equivalent to a listening state. No
data is forwarded across the port. Thus, the guard root enforces the root
bridge position.
