DESCRIPTION
|
|
"The objects in this MIB module are used to describe
|
|
cross-connect capabilities of stacked (layered) interfaces,
|
|
complementing ifStackTable and ifInvStackTable defined in
|
|
IF-MIB and IF-INVERTED-STACK-MIB, respectively.

DESCRIPTION
|
|
"This table, modeled after ifStackTable from IF-MIB,
|
|
contains information on the possible 'on-top-of'
|
|
relationships between the multiple sub-layers of network
|
|
interfaces (as opposed to actual relationships described in
|
|
ifStackTable). In particular, it contains information on
|
|
which sub-layers MAY possibly run 'on top of' which other
|
|
sub-layers, as determined by cross-connect capability of the
|
|
device, where each sub-layer corresponds to a conceptual row
|
|
in the ifTable. For example, when the sub-layer with ifIndex
|
|
value x can be connected to run on top of the sub-layer with
|
|
ifIndex value y, then this table contains:
|
|
|
|
ifCapStackStatus.x.y=true
|
|
|
|
The ifCapStackStatus.x.y row does not exist if it is
|
|
impossible to connect between the sub-layers x and y.
|
|
|
|
Note that for most stacked interfaces (e.g., 2BASE-TL)
|
|
there's always at least one higher-level interface (e.g., PCS
|
|
port) for each lower-level interface (e.g., PME) and at
|
|
least one lower-level interface for each higher-level
|
|
interface, that is, there is at least a single row with a
|
|
'true' status for any such existing value of x or y.
|
|
|
|
This table is read-only as it describes device capabilities."

DESCRIPTION
|
|
"The status of the 'cross-connect capability' relationship
|
|
between two sub-layers. The following values can be returned:
|
|
true(1) - indicates that the sub-layer interface,
|
|
identified by the ifStackLowerLayer MAY
|
|
be connected to run 'below' the sub-layer
|
|
interface, identified by the
|
|
ifStackHigherLayer index.
|
|
false(2) - the sub-layer interfaces cannot be
|
|
connected temporarily due to
|
|
unavailability of the interface(s), e.g.,
|
|
one of the interfaces is located on an
|
|
absent pluggable module.
|
|
|
|
Note that lower-layer interface availability per higher-layer,
|
|
indicated by the value of 'true', can be constrained by
|
|
other parameters, for example, by the aggregation capacity of
|
|
a higher-layer interface or by the lower-layer interface in
|
|
question being already connected to another higher-layer
|
|
interface. In order to ensure that a particular sub-layer can
|
|
be connected to another sub-layer, all respective objects
|
|
(e.g., ifCapStackTable, ifStackTable, and efmCuPAFCapacity for
|
|
EFMCu interfaces) SHALL be inspected.
|
|
|
|
This object is read-only, unlike ifStackStatus, as it
|
|
describes a cross-connect capability."

"A table containing information on the possible relationships

table, modeled after ifInvStackTable from

IF-INVERTED-STACK-MIB, is an inverse of the ifCapStackTable

|
defined in this MIB module.
|
|
|
|
In particular, this table contains information on which
|
|
sub-layers MAY run 'underneath' which other sub-layers, where
|
|
each sub-layer corresponds to a conceptual row in the ifTable.
|
|
For example, when the sub-layer with ifIndex value x MAY be
|
|
connected to run underneath the sub-layer with ifIndex value
|
|
y, then this table contains:
|
|
|
|
ifInvCapStackStatus.x.y=true
|
|
|
|
This table contains exactly the same number of rows as the
|
|
ifCapStackTable, but the rows appear in a different order.

|

This table is read-only as it describes a cross-connect
