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."
