Configuring eRSTP
Description
cannot run the link in full-duplex mode. Force the parameter false
when the port operates the link in full-duplex mode, but is still not
point-to-point (e.g. a full-duplex link to an unmanaged bridge that
concentrates two other STP bridges).
Synopsis: { True or False }
Default: False
A boolean value set by management. If TRUE, causes the Port
not to be selected as the Root Port for the 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. This parameter should be FALSE by default. If set, it can
cause a lack of spanning tree connectivity. It is set by a network
administrator to prevent bridges that are external to a core
region of the network from influencing the spanning tree active
topology. This may be necessary, for example, if those bridges are
not under the full control of the administrator.
Synopsis: { True or False }
Default: False
A boolean value set by management. If TRUE, it causes the Port
not to propagate received topology change notifications and
topology changes to other Ports. If set, it can cause temporary
loss of connectivity after changes in a spanning tree's active
topology as a result of persistent, incorrectly learned, station
location information. It is set by a network administrator to
prevent bridges that are external to a core region of the network
from causing address flushing in that region. This may be
necessary, for example, if those bridges are not under the full
control of the administrator or if the MAC_Operational status
parameter for the attached LANs transitions frequently.
