.1.3.6.1.2.1.17.3.1.1.1 |
|
The port number of the port for which this entry
contains Source Route management information.
|
| dot1dSrPortHopCount |
.1.3.6.1.2.1.17.3.1.1.2 |

The maximum number of routing descriptors allowed
in an All Paths or Spanning Tree Explorer frames.
|
| dot1dSrPortLocalSegment |
.1.3.6.1.2.1.17.3.1.1.3 |
|
The segment number that uniquely identifies the
segment to which this port is connected. Current
source routing protocols limit this value to the
range: 0 through 4095. (The value 0 is used by
some management applications for special test
cases.) A value of 65535 signifies that no segment
number is assigned to this port.
|
| dot1dSrPortBridgeNum |
.1.3.6.1.2.1.17.3.1.1.4 |
|
A bridge number uniquely identifies a bridge when
more than one bridge is used to span the same two
segments. Current source routing protocols limit
this value to the range: 0 through 15. A value of
65535 signifies that no bridge number is assigned
to this bridge.
|
| dot1dSrPortTargetSegment |
.1.3.6.1.2.1.17.3.1.1.5 |
|
The segment number that corresponds to the target
segment this port is considered to be connected to
by the bridge. Current source routing protocols
limit this value to the range: 0 through 4095.
(The value 0 is used by some management
applications for special test cases.) A value of
65535 signifies that no target segment is assigned
to this port.
|
| dot1dSrPortLargestFrame |
.1.3.6.1.2.1.17.3.1.1.6 |
|
The maximum size of the INFO field (LLC and
above) that this port can send/receive. It does
not include any MAC level (framing) octets. The
value of this object is used by this bridge to
determine whether a modification of the
LargestFrame (LF, see [14]) field of the Routing
Control field of the Routing Information Field is
necessary.

An illegal value will not be accepted by the
bridge.
|
| dot1dSrPortSTESpanMode |
.1.3.6.1.2.1.17.3.1.1.7 |
|
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.

|
The number of ARE and STE frames that were
discarded because the last LAN ID in the routing
information field did not equal the LAN-in ID.
This error can occur in implementations which do
only a LAN-in ID and Bridge Number check instead
of a LAN-in ID, Bridge Number, and LAN-out ID
check before they forward broadcast frames.
