dot1dSrPortSTESpanMode OBJECT-TYPE
SYNTAX INTEGER {
auto-span(1),
disabled(2),
forced(3)
}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"Determines how this port behaves when presented
with a Spanning Tree Explorer frame. The value
'disabled(2)' indicates that the port will not
accept or send Spanning Tree Explorer packets; any
STE packets received will be silently discarded.
The value 'forced(3)' indicates the port will
always accept and propagate Spanning Tree Explorer
frames. This allows a manually configured
Spanning Tree for this class of packet to be
configured. Note that unlike transparent
bridging, this is not catastrophic to the network
if there are loops. The value 'auto-span(1)' can
only be returned by a bridge that both implements
the Spanning Tree Protocol and has use of the
protocol enabled on this port. The behavior of the
port for Spanning Tree Explorer frames is
determined by the state of dot1dStpPortState. If
the port is in the 'forwarding' state, the frame
will be accepted or propagated. Otherwise, it
will be silently discarded."
