Setting this parameter as Yes will set the ports to send out BPDU packets to other
bridges, requesting information on their STP setting If the Switch is configured for RSTP,
the port will be capable to migrate from 802.1D STP to 802.1w RSTP. Migration should be
set as yes on ports connected to network stations or segments that are capable of being
upgraded to 802.1w RSTP on all or some portion of the segment.
Choosing the True parameter 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. Choosing the Auto parameter
will indicate that the port will be able to automatically enable edge port status if needed.
The default setting is False.
Choosing the True parameter 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. The
default setting for this parameter is True. The default value True is equivalent to the Auto
value.
Allows STP to be Enabled or Disabled for the ports.
Toggle between True and False to set whether this port is restricted to be selected as a
root port. The default value is False.
Toggle between True and False to set whether this port is restricted to be selected as a
propagate topology change. The default value is False.
This field can be Enabled or Disabled. When Enabled, it allows the forwarding of STP
BPDU packets from other network devices. The default is Disabled.
