| trkPaIndex |
.1.3.6.1.4.1.562.2.4.1.60.4.1.1.10 |
|
This variable represents the index for the trkPa tables.
|
| trkPaRowStatus |
.1.3.6.1.4.1.562.2.4.1.60.4.1.1.1 |
|
This variable is used as the basis for SNMP naming of
trkPa components.
These components can be added and deleted.
|
| trkPaComponentName |
.1.3.6.1.4.1.562.2.4.1.60.4.1.1.2 |
|
This variable provides the component's string name for
use with the ASCII Console Interface
|
| trkPaStorageType |
.1.3.6.1.4.1.562.2.4.1.60.4.1.1.4 |
|
This variable represents the storage type value for the
trkPa tables.
|
| trkPaMaxLc |
.1.3.6.1.4.1.562.2.4.1.60.4.10.1.1 |
|
This attribute indicates the number of Logical Channels (LCh/n)
supported on this trunk. This attribute is used to allocate memory on
the trunk FP for the PORS forwarding tables.Unless running in
mapped mode on ATM hardware, the PathAdmin will add 100
channels to maxLc to reduce the chances of allocation clashes.
However, you should never see more than maxLc channels in use
for any extended period of time. On ATM hardware in mapped
mode the PathAdmin will only add 10 channels to maxLc to permit
more efficient use of the available VCC space.
The PathAdmin may not be able to honor a request for maxLc
channels. This will happen when the neighbor PathAdmin asks for
less channels than this PathAdmin. To resolve the conflict the
PathAdmin will always pick the minimum of the two maxLc values.
This minimum value is called the negotiatedMaxLc and can be
viewed as an operational parameter of the PathAdmin.
Note that in mapped mode on ATM hardware, the value of this
attribute provides an upper bound to the number of VCCs that this
Trunk/n PathAdmin can occupy. It is not a guarantee that maxLc
VCCs will be available to this PathAdmin because the VCC space is
a shared resource on the card or port.
|
| trkPaMaxReservedBwOut |
.1.3.6.1.4.1.562.2.4.1.60.4.10.1.2 |
|
This attribute controls the percentage of trunk bandwidth which
may be reserved by outgoing path oriented traffic on the trunk. The
sum of requiredBandwidth attributes for all paths on this trunk must
not exceed this attribute. Setting this attribute to zero (0) prevents
paths from being established on this trunk. The limit of reserved
bandwidth for incoming path oriented traffic is set using the same
attribute on the trunk component on the other end of the trunk.This
attribute may be changed without the trunk being restaged. If the
value is decreased, calls may be bumped as necessary to free up
bandwidth. Increasing the value has no impact on existing calls and
new calls are able to use the new bandwidth.
If this attribute is set to greater than 100%, connectionless traffic is
given a minimum of 1Kbit per second for administrative traffic. A
value greater than 100% overbooks the trunk bandwidth. By
overbooking bandwidth, more calls are able to be established using
the unused bandwidth reserved by idle PLCs.
|
| trkPaTrunkSecurity |
.1.3.6.1.4.1.562.2.4.1.60.4.10.1.3 |
|
This attribute indicates the security level of the trunk. Zero(0)
represents the most secure trunk and seven(7) represents the least
secure. The path's minimum security requirement is indicated by
the Plc requiredSecurity attribute, with values identical in range and
meaning to this attribute. PORS ensures that the route selected does
not contain a trunk whose PathAdmin trunkSecurity attribute is
numerically greater than the path's requiredSecurity.
|
| trkPaSupportedTrafficTypes |
.1.3.6.1.4.1.562.2.4.1.60.4.10.1.4 |
|
This attribute indicates the type of traffic that can be transmitted on
the trunk. There are eight(8) possible traffic types, and the trunk can
transmit all of them if desired. The voice, data and video traffic
types are defined, and five(5) other traffic types can be defined by
the network administration. This attribute is used in the route
selection process to limit the route to trunks that support the traffic
type carried by the path. The requiredTrafficType attribute of the
PLC indicates the type of traffic carried on the path.
Description of bits:
voice(0)
data(1)

trafficType1(3)
trafficType2(4)
trafficType3(5)
trafficType4(6)
trafficType5(7)
|
| trkPaTrunkType |
.1.3.6.1.4.1.562.2.4.1.60.4.10.1.5 |
|
This attribute lists the type of the trunk. There can be up to eight(8)
types of trunks. The terrestrial and satellite trunk types have been
defined, leaving six(6) remaining types that can be defined by the
network administration. The set of allowed trunk types for a path is
indicated in the permittedTrunkType attribute of the PLC. When
selecting a route, PORS only chooses trunks whose PathAdmin
trunkType are in the permittedTrunkTypes set of the path.
|
| trkPaCustomerParameter |
.1.3.6.1.4.1.562.2.4.1.60.4.10.1.6 |
|
This attribute indicates the customer defined parameter for the
trunk. Its value, a number from zero(0) to seven(7), is chosen by a
network administration to have a meaning specific to their network,
thus allowing them to customize the use of their trunks. A
complementary PLC attribute, requiredCustomerParameter, also
has a value from zero(0) to seven(7). The Route Selector does not
consider trunks whose PathAdmin customerParameter is greater
than the requiredCustomerParameter of the path.
|
| trkPaTrunkCost |
.1.3.6.1.4.1.562.2.4.1.60.4.10.1.7 |
|
This attribute is the cost metric for the trunk. This value is assigned
by the network administration to represent the network cost of using
this trunk. It can be related to distance, speed, dollars, or any other
factor that could be taken into consideration. If the
trunkAttributeToMinimize is set to trunkCost, PORS finds a route
with the smallest sum of the PathAdmin trunkCost attribute over all
trunks. The trunk cost can be increased or decreased without
disrupting the service to the link. If it is increased and the PORS
optimization feature is enabled calls will move off this link to lower
cost links when possible. If the cost is decreased new calls will be
attracted to this link.
|
| trkPaOverrideTrunkDelay |
.1.3.6.1.4.1.562.2.4.1.60.4.10.1.8 |
|
This attribute specifies the override value of parent trunk's half
round trip delay (propagation delay), which is used by the
PathAdmin to negotiate the value of negotiatedTrunkDelay. A value
of zero indicates that an override value has not been provided, and
that the measured propagation delay value is used for negotiation.
|
| trkPaState |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.1 |
|
This attribute gives the operational state of the PathAdmin
component. The PathAdmin may be up, down, goingDown, staging
or downWaitingRestage.
|
| trkPaUsedLc |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.2 |
|
This attribute gives the total number of Logical Channels currently
busy on the trunk. When this number reaches maxLc, no more paths
are allowed to instantiate through this trunk. Note that it is possible
for usedLc to be less than maxLc but for there to be no currently
free LogicalChannels. This is because a LogicalChannel can be in
one of several intermediate states between free and busy.
|
| trkPaNegotiatedMaxLc |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.3 |
|
This attribute gives the actual value of maxLc that the PathAdmin
has decided on after negotiation with the far end PathAdmin. If
there is disagreement between the two PathAdmin's maxLc
provisionable attributes the smaller of the two is chosen on both
sides. This attribute reflects the minimum of these two maxLc's.
|
| trkPaMaxReservableBwOut |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.4 |
|
This attribute gives the total bandwidth that this PathAdmin is
allowed to reserve. This number is computed by multiplying the
parent trunk's measuredSpeedToIf attribute by the
maxReservedBwOut provisionable attribute of this PathAdmin.
|
| trkPaOverReservedBwOut |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.5 |
|
When bumping is required to free up enough bandwidth for a new
path there exists a short period of time when both the new path and
the soon to be bumped path are occupying the same bandwidth.
This means that the total amount of reserved bandwidth will exceed
maxReservableBwOut. When this happens the unreservedBwOut
attribute will be 0 and the overReservedBwOut attribute will be non-
zero to indicate by how much we are currently overcommitted. This
value should quickly drop back to zero as the bumping starts to
clear the lower holdingPriority calls.
|
| trkPaUnreservedBwOut |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.6 |
|
This attribute gives the total of amount of bandwidth that is still
available for reservation by new connections. When this number
reaches 0 the PathAdmin will no longer admit new connections to
the trunk. This number represents available bandwidth in the
outward going direction. To determine the inward available
bandwidth you must query the PathAdmin at the other end of this
Trunk.
|
| trkPaClashCount |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.7 |
|
This attribute gives the total number of path setup requests that
resulted in an LCh/n or Vcc/x.y clash. A large value for this number
is an indicator of poor performance by the PathAdmin in its
allocation of LCh/n or Vcc/x.y components. In general the channels
will be allocated in opposite orders at each end of the Trunk but this
may not always be the case. Note that as the PathAdmin runs out of
LCh/n or Vcc/x.y components the number of clashes will increase.
|
| trkPaNegotiatedSupportedTrafficTypes |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.9 |
|
This attribute gives the actual value of supportedTrafficTypes that
the PathAdmin has decided on after negotiation with the far end
PathAdmin. If there is disagreement between the two PathAdmin's
supportedTrafficTypes provisionable attributes the union of the two
is chosen on both sides. This attribute reflects the union of these two
supportedTrafficTypes 's. It is this union that is advertised to all
other nodes in the network and which is used for routing decisions.
Description of bits:
voice(0)
data(1)

|
| trkPaNegotiatedTrunkSecurity |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.10 |
|
This attribute gives the actual value of the trunkSecurity that the
PathAdmin has decided on after negotiation with the far end
PathAdmin. If there is disagreement between the two PathAdmin's
trunkSecurity provisionable attributes the larger of the two is chosen
on both sides. This attribute reflects the maximum of these two
trunkSecurity's.
|
| trkPaNegotiatedCustomerParameter |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.11 |
|
This attribute gives the actual value of customerParameter that the
PathAdmin has decided on after negotiation with the far end
PathAdmin. If there is disagreement between the two PathAdmin's
customerParameter provisionable attributes the larger of the two is
chosen on both sides. This attribute reflects the maximum of these
two customerParameter's.
|
| trkPaNegotiatedTrunkCost |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.12 |
|
This attribute gives the actual value of trunkCost that the
PathAdmin has decided on after negotiation with the far end
PathAdmin. If there is disagreement between the two PathAdmin's
trunkCost provisionable attributes the larger of the two is chosen on
both sides. This attribute reflects the maximum of these two
trunkCost's.
|
| trkPaNegotiatedAtmMode |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.13 |
|
This attribute gives the actual value of PathAdmin Atm mode that
the PathAdmin has decided on after negotiation with the far end
PathAdmin. This is only applicable to ATM cards since the mode on
non ATM hardware is not specified. The multiplexing mode implies
that all voice traffic will be multiplexed onto the Atm
atmConnection Vcc and all data will be multiplexed onto the Trunk
Atm atmConnection Vcc. The mapping mode implies that each
unique logical channel will be allocated its own Vcc. The mode
notApplicable implies either this is not ATM hardware or that no
Atm subcomponent exists under this or the peer PathAdmin.
|
| trkPaNegotiatedTrunkDelay |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.14 |
|
This attribute gives the actual value of parent trunk's half round trip
delay (propagation delay) that the PathAdmin has decided on after
negotiation with the far end PathAdmin. If there is disagreement
between the two PathAdmins the larger of the two propagation
delays is chosen on both sides. This attribute reflects the maximum
of these two propagation delays.
|
| trkPaNegotiatedTrunkType |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.15 |
|
This attribute gives the actual value of trunkType that the
PathAdmin has decided on after negotiation with the far end
PathAdmin. If there is disagreement between the two PathAdmin's
trunkType provisionable attributes the provisioned values are used
on both sides. That is, both sides maintain their provisioned value..
|
| trkPaAdaptationLevel |
.1.3.6.1.4.1.562.2.4.1.60.4.11.1.16 |
|
This attribute indicates the current PORS adaptation level of the
parent trunk. The adaptation mechanism is controlled by Adaptation
group, which is used to alleviate the high utilization condition on
the parent trunk.
0 - adaptation is not active.
1 - new calls are prevented from being established over the parent
trunk.
2 - some connections starting from the lowest holdingPriority
attempt to reroute their paths using alternate trunks.
3 - some connections starting from the lowest holdingPriority are
bumped away from the parent trunk.
|
| trkPaMaxAdaptationLevel |
.1.3.6.1.4.1.562.2.4.1.60.4.12.1.1 |
|
This attribute specifies the maximum adaptation level that the parent
trunk can reach. It determines the highest degree of adaptation that
can be triggered by high trunk utilization.
When the first degree of adaptation is triggered, new calls are
prevented from being established over the parent trunk, and the
adaptationLevel changes to level one (1).
When the second degree of adaptation is triggered, some
connections starting from the lowest holdingPriority attempt to
reroute their paths using alternate trunks, and the adaptationLevel
changes to level two (2).
When the third degree of adaptation is triggered, some connections
starting from the lowest holdingPriority are bumped away from the
parent trunk, and the adaptationLevel changes to level three (3).
The configurable values are:
0 - The adapation mechanism is disabled.
1 - Only the first degree of adaptation can be triggered.
2 - Up to two degrees of adaptation can be triggered.
3 - Up to three degrees of adaptation can be triggered.
Regardless of its value, the operator command CLEAR -hotSwap or
CLEAR (without an option) can always be issued on a particular
LCh/n to cause the entire path to be rerouted if possible or bumped.
|
| trkPaAdaptationBandwidth |
.1.3.6.1.4.1.562.2.4.1.60.4.12.1.2 |
|
This attribute specifies the amount of bandwidth to be potentially
freed up by rerouting connections if possible or freed up by
bumping connections on the trunk when the second or third degree
of adaptation is triggered.
The adaptationBandwidth value is used to determine the number of
connections to be rerouted or bumped starting from the lowest
holdingPriority, such that the total of the chosen connections
reserved outgoing bandwidth requiredTxBandwidth reaches this
adaptationBandwidth value.
If its value is greater than the maxReservableBwOut of Trunk/n Pa,
the maxReservableBwOut amount of bandwidth is used for
rerouting or bumping.

.1.3.6.1.4.1.562.2.4.1.60.5.1.1.1 |
|
This variable is used as the basis for SNMP naming of
trkLCh components.
These components cannot be added nor deleted.
|
| trkLChComponentName |
.1.3.6.1.4.1.562.2.4.1.60.5.1.1.2 |
|
This variable provides the component's string name for
use with the ASCII Console Interface
|
| trkLChStorageType |
.1.3.6.1.4.1.562.2.4.1.60.5.1.1.4 |
|
This variable represents the storage type value for the
trkLCh tables.
|
| trkLChNextHop |
.1.3.6.1.4.1.562.2.4.1.60.5.10.1.2 |
|
The nextHop is the name of the component across the bus which is
forwarding packets to us. Inversely the nextHop of our nextHop
component is us. More precisely, LCh/n components point to each
other across the bus via their nextHop attributes. In the case where
the next hop is an application the nextHop attribute will indicate the
component name of this application.
|
| trkLChSetupPriority |
.1.3.6.1.4.1.562.2.4.1.60.5.10.1.3 |
|
This attribute gives the priority at which a path is established. Zero
(0) is the highest priority and four (4) is the lowest. When PORS
establishes a path through the network, it uses the setupPriority
attribute to determine its potential for bumping established paths to
acquire their bandwidth. The holdingPriority, a complementary
attribute of this component, indicates the priority a path maintains
once it is established. A new path can bump an existing path if the
new path's setupPriority is higher (or numerically less) than the
existing path's holdingPriority.
|
| trkLChHoldingPriority |
.1.3.6.1.4.1.562.2.4.1.60.5.10.1.4 |
|
This attribute gives the priority that a path holds once it is
established. Zero (0) is the highest priority and four (4) is the
lowest. A path's holdingPriority determines its likelihood of being
bumped by a new path to acquire its bandwidth. The setupPriority, a
complementary attribute, indicates the priority of a path at
establishment time. A new path can bump an existing path if the
new path's setupPriority is higher (or numerically less) than the
existing path's holdingPriority.
|
| trkLChEmissionPriority |
.1.3.6.1.4.1.562.2.4.1.60.5.10.1.5 |
|
This attribute indicates the urgency with which packets on the
LCh's path are emitted by this trunk. The emissionPriority
translates into the trunk's emission queue. Zero (0) indicates the
highest emissionPriority, while three (3) indicates the lowest.
Packets with a higher emissionPriority (or numerically less) are put
on an emission queue which is serviced before a queue which
accepts packets of a lower emissionPriority and hence experience
smaller delays traversing congested trunks.
|
| trkLChDiscardPriority |
.1.3.6.1.4.1.562.2.4.1.60.5.10.1.6 |
|
This attribute indicates the importance of the packets on the path.
Zero (0) is used for paths carrying the most important traffic, and
two (3) is used for paths carrying the least important traffic. In times
of congestion, the discardPriority is used by packet forwarding on
the trunk to determine which packets are discarded first to reduce
the load. Packets with a higher discardPriority (or numerically less)
are discarded after packets with a lower discardPriority (or
numerically higher).
|
| trkLChRequiredTxBandwidth |
.1.3.6.1.4.1.562.2.4.1.60.5.10.1.7 |
|
This attribute gives the bandwidth (in bits per second units)
reserved by this LCh/n for emitting packets on the trunk.
|
| trkLChRequiredRxBandwidth |
.1.3.6.1.4.1.562.2.4.1.60.5.10.1.8 |
|
This attribute gives the bandwidth (in bits per second units)
reserved by this LCh/n for receiving packets on the trunk.
|
| trkLChMode |
.1.3.6.1.4.1.562.2.4.1.60.5.10.1.9 |
|
This attribute gives the operational mode of the LogicalChannel
component. It indicates what kind of transport is being performed
on the packets in the channel. There are 7 possible values of this
attribute as follows:
unknown - not currently in busy state, type of forwarding not
determined yet.
hdlcFrmMux - frames are being multiplexed (multiple LCh/n on
same port or channel) using HDLC encapsulation.
aal5FrmMux - frames are being multiplexed (multiple LCh/n on
same ATM VCC) using the AAL5 segmentation and recombination
protocol.
spoFrmMux - frames are being multiplexed (multiple LCh/n on
same ATM VCC) using the Short Path Oriented segmentation and
recombination protocol. This is a proprietary protocol which
encapsulates voice frames into a single ATM cell unlike AAL5
which would require two cells to transport the 45 byte voice frames.
aal5FrmMap - frames are being mapped (a single LCh/n per ATM
VCC) using the AAL5 segmentation and recombination protocol.
AAL5 mapped frames are forwarded by hardware in both directions
and require no CPU intervention.
spoFrmMap - frames are being mapped (a single LCh/n per ATM
VCC) using the Short Path Oriented segmentation and
recombination protocol. SPO mapped frames are forwarded by
hardware in both directions and require no CPU intervention in all
but one special case. In particular CPU is required only if frames
are being forwarded to an LCh/n whose mode is spoFrmMux.
cellMap - ATM cells are being relayed directly over the bus with no
segmentation and recombination protocol. The segmentation and
recombination is only done at transition points between frame based
cards and ATM cell based cards so this hop represents a pure
tandem cell hop, ATM card to ATM card. No CPU is required to
process these cells.
|
| trkLChMaximumTransmissionUnit |
.1.3.6.1.4.1.562.2.4.1.60.5.10.1.10 |
|
This attribute gives the size of the largest frame this service will
send. A value of 0 means that the Mtu is unknown. A value of 45 or
less (but non zero) means that ATM single cell transport will be
used wherever possible. Otherwise ATM AAL5 adaption layer
transport will be required to handle all frames.
|
| trkLChLocalConnection |
.1.3.6.1.4.1.562.2.4.1.60.5.10.1.11 |
|
The localConnection attribute specifies the name of the connection
on the local interface. On ATM hardware this is in the form AtmIf/n
Vcc/x.y. On non ATM hardware this attribute is empty.
|

percentage of the outgoing trunk bandwidth.
|
| trkPaOperTable |
.1.3.6.1.4.1.562.2.4.1.60.4.11 |
|
This group contains all operational attributes relevant to path
oriented and connectionless bandwidth utilization and path activity
on a trunk.
|
| trkPaAdaptationTable |
.1.3.6.1.4.1.562.2.4.1.60.4.12 |
|
This group of provisionable attributes controls the PORS adaptive
routing mechanism. Adaptation is triggered by high trunk
utilization, and is used to alleviate the high utilization condition on
the parent Trunk/n component.
For a Trunk/n with an Unack subcomponent, the link receive
utilization (indicated by utilization of Trunk/n) is used for triggering
adaptation.
For a Trunk/n with an AtmAccess subcomponent, the aggregation of
the transmit VCCs utilization (indicated by utilization of Trunk/n),
VP utilization, and PORT utilization (normal port or IMA port if
Ima is used) is used for triggering adaptation.
|
| trkPaRbwTable |
.1.3.6.1.4.1.562.2.4.1.60.4.214 |

.1.3.6.1.4.1.562.2.4.1.60.4.653 |
|
This attribute specifies three utilization thresholds used to trigger
the three degrees of adaptation. It is a vector indexed by (level1,
level2, and level3).
While the PORS adaptationLevel is zero (0),
- if the trunk utilization has exceeded the level1 value for the period
of time specified by the set value of adaptationHoldOffTime, the
first degree of adaptation is triggered. Meanwhile, the Trunk/n Pa
component generates a SET alarm indicating that the PORS
adaptation mechanism is active. The PORS adaptationLevel
increases to level one (1).
While the PORS adaptationLevel is one (1),
- if the trunk utilization has exceeded the level2 value for the period
of time specified by the set value of adaptationHoldOffTime, the
second degree of adaptation is triggered. The PORS
adaptationLevel increases to level two (2).
- Otherwise, if the trunk utilization has exceeded the level1 value
for an additional period of time specified by the set value of
adaptationHoldOffTime, the PORS adaptationLevel remains
unchanged.
- Otherwise, if the trunk utilization has subsequently fallen back to
a level at or below the level1 value for the period of time specified
by the clear value of adaptationHoldOffTime, new calls are allowed
to be established over the parent trunk. Meanwhile, the Trunk/n Pa
component generates a CLEAR alarm indicating that the PORS
adaptation mechanism is no longer active. The PORS
adaptationLevel decreases to level zero (0).
While the PORS adaptationLevel is two (2),
- if the trunk utilization has exceeded the level3 value for the period
of time specified by the set value of adaptationHoldOffTime, the
third degree of adaptation is triggered. The PORS adaptationLevel
increases to level three (3).
- Otherwise, if the trunk utilization has exceeded the level2 value
for an additional period of time specified by the set value of
adaptationHoldOffTime, the second degree of adaptation is
triggered again, and the PORS adaptationLevel remains unchanged.
- Otherwise, if the trunk utilization has subsequently fallen back to
a level at or below the level2 value for the period of time specified
by the clear value of adaptationHoldOffTime, the PORS
adaptationLevel decreases to level one (1).
While the PORS adaptationLevel is three (3),
- if the trunk utilization has exceeded the level3 value for an
additional period of time specified by the set value of
adaptationHoldOffTime, the third degree of adaptation is triggered
again, and the PORS adaptationLevel remains unchanged.
- Otherwise, if the trunk utilization has subsequently fallen back to
a level at or below the level3 value for the period of time specified
by the clear value of adaptationHoldOffTime, the PORS
adaptationLevel decreases to level two (2).
For a Trunk/n with an Unack subcomponent, the link receive
utilization (indicated by utilization of Trunk/n) is monitored against
the thresholds. Since the trunk application solely owns the physical
link, the maximum link receive utilization is 100%. The restrictions
on the setting of the three thresholds are:
- when maxAdaptationLevel is 1, the value of (level1) must be in the
range of 0% to 100%.
- when maxAdaptationLevel is 2, the values of (level1 and level2)
must be the range of 0% to 100%, and the value of level1 must be
less than or equal to the value of level2.
- when maxAdaptationLevel is 3, the values of (level1, level2, and
level3) must be in the range of 0% to 100%, and the value of level1
must be less than or equal to the value of level2, which must be less
than or equal to the value of level3.
For a Trunk/n with an AtmAccess subcomponent, the aggregation of
transmit VCCs utilization (indicated by utilization of Trunk/n), VP
utilization, and PORT utilization (normal port or IMA port if Ima is
used) is monitored against the thresholds. Since the trunk
application shares a physical link with other applications, both the
VCCs and VP utilizations can exceed 100%, and the value 200% is
chosen as the maximum calculated utilization for VCCs and VP, so
all thresholds can take on any value in the range of 0% to 200%.
The restrictions on the setting of the three thresholds are:
- when maxAdaptationLevel is 2, the value of level1 must be less
than or equal to the value of level2.
- when maxAdaptationLevel is 3, the value of level1 must be less
than or equal to the value of level2, which must be less than or
equal to the value of level3.

This attribute specifies two interval times. It is a vector indexed by
(set clear). The set value specifies the period of time for which the
trunk utilization must be above the utilization threshold specified by
adaptationThreshold before the corresponding degree of adaptation
is triggered. The clear value specifies the period of time for which
the trunk utilization must be at or below the utilization threshold
specified by adaptationThreshold before the PORS adaptationLevel
is decreased by one (1).
