
Path Cost : indicates the path cost value that will be
announced by the port to other bridges. Lower path costs
mean higher port speed, and they are chosen to forward
traffic at the expenses of higher path costs. Allowed
values are Auto and Specific. If Auto is selected, path
costs will be calculated based on port speed capabilities
as recommended at the 802.1D standard. If Specific is
selected, path cost used will be the path cost defined by
user at the field allowed in the Path Cost column. Allowed
path costs values are integer values from 1 to 200000000;

Priority : indicates the priority of the port. If there are two
paths between Bridges with the same path cost, the
priority field will be used to choose which port should
forward traffic. Lower values mean higher priority for the
port. Allowed values are integer numbers from 0 to 240;
 Admin Edge : indicates status flag of the Edge operation
when port is initialized. Allowed values are Non-Edge and
Edge. Non-Edge means that Edge operation flag will be
initialized with value equal 0, and Edge means that Edge
operation flag will be initialized with value equal 1;
 Auto Edge : enable Auto-Edge port detection at the port.
This checkbox allow the switch to detect if a port is an
Edge or Trunk spanning tree port automatically. Checkbox
selected means Auto-edge detection enabled, and
checkbox empty means disabled;
 Restricted : enables Root guard functions. If it is desired to
control ports to not propagate topology changes or not to
be root ports, to guarantee that that ports are not in the
main catenet of the logical topology, Root guard functions
should be enabled. Possible values are as follows:

Restricted Role : enable Root guard function. This
checkbox allow the port to guarantee that the
port will not be a Root port, even if it is the best
path to the root. Checkbox selected means that
the port will not operate root port, and checkbox
empty means port could be selected as root port;

Restricted TCN : enable the port to not
propagate notifications and topology changes
received in that port to other ports. This can be
used to ports connected to networks that
changes frequently. Checkbox selected means
that the port will not propagate topology change
and notification messages, and checkbox empty
means port will propagate these messages;
