Example usage:
To configure STP with path cost set at auto, priority 16, and state enabled for ports 1-5 of module 1.

cost This defines a metric that indicates the relative cost of
forwarding packets to the specified port list. Port cost can be set in
the following two ways:
§ auto – Setting this parameter for the cost will automatically
set the speed for forwarding packets to the specified port(s) in
the list for optimal efficiency. Default port cost: 100Mbps port
= 200000. Gigabit port = 20000.
§ <value 1-200000000> - Define a value between 1 and
200000000 to determine the external cost. The lower the
number, the greater the probability the port will be chosen to
forward packets.
Default port cost: 100Mbps port = 200000
Gigabit port = 20000
priority <value 0-240>
lower the number, the greater the probability the port will be
chosen as the Root Port. Default = 128.
<portlist> Specifies a port or range of ports to be configured.
migrate [yes | no] – yes will enable the port to migrate from 802.1d
STP status to 802.1w RSTP status. RSTP can coexist with
standard STP, however the benefits of RSTP are not realized on a
port where an 802.1d network connects to an 802.1w enabled
network. Migration should be enabled (yes) on ports connected to
network stations or segments that will be upgraded to 802.1w
RSTP on all or some portion of the segment.
edge [true | false] – true designates the port as an edge port. Edge
ports cannot create loops, however an edge port can lose edge
port status if a topology change creates a potential for a loop. An
edge port normally should not receive BPDU packets. If a BPDU
packet is received it automatically loses edge port status. false
indicates that the port does not have edge port status.
p2p [true | false | auto] – true indicates a point-to-point (P2P)
shared link. P2P ports are similar to edge ports however they are
restricted in that a P2P port must operate in full-duplex. Like edge
ports, P2P ports transition to a forwarding state rapidly thus
benefiting from RSTP. A p2p value of false indicates that the port
cannot have p2p status. auto allows the port to have p2p status
whenever possible and operate as if the p2p status were true. If
the port cannot maintain this status (for example if the port is
forced to half-duplex operation) the p2p status changes to operate
as if the p2p value were false.
state [enable | disable]
the ports specified in the port list. The default is disabled.
