Description
Port
The switch port number to which the following settings will be
applied.
STP Enabled
Check to enable STP for the port
Path Cost
Configures the path cost incurred by the port.
Auto
will set the
path cost according to the physical link speed by using the
802.1D-recommended values.
Specific
allows you to enter a
user-defined value. The path cost is used when establishing an
active topology for the network. Lower path cost ports are chosen
as forwarding ports in favor of higher path cost ports. The range of
valid values is 1 to 200000000.
Priority
Configures the priority for ports having identical port costs. (See
above).
OpenEdge
(setate
flag)
A flag indicating whether the port is connected directly to edge
devices or not (no bridges attached). Transiting to the forwarding
state is faster for edge ports (
operEdge
set to true) than other
ports.
AdminEdge
Configures the operEdge flag to start as set or cleared.(the initial
operEdge state when a port is initialized).
AutoEdge
Check to enable the bridge to detect edges at the bridge port
automatically. This allows
operEdge
to be derived from whether
BPDUs are received on the port or not.
Restricted Role
When enabled, the port will not be selected as root port for CIST
or any MSTI, even if 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. If set, spanning trees will lose connectivity. It
