The MIB to manage CoS(Class of Service) queue/buffer related parameters. One or more virtual interfaces may exist on a physical
interface or a channelized interface. Every virtual
interface has certain number (e.g. 16) of CoS queues. These queues are also known as Class Of Service Buffers. Every COS queue maps to an ATM trafiic type such as CBR, VBR-rt, ABR etc. These COS queues are used to provide QOS (quality of service), depending on the corresponding
ATM trafiic type. This MIB provides management
functionality such as Threshold Crossing Alarms(TCA) for cell discards and interval statistics for these COS queues.
This table contains alarm configuration parameters related to CoS queue. Entries in this table are automatically created when a new virtual interface is added.
InterfaceIndexA unique value, greater than zero, for each interface or interface sub-layer in the managed system. It is recommended that values are assigned contiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization.

cwacCosbIndex
1.3.6.1.4.1.351.150.16.1.2.1.1.1
Integer32 (1..32)
This is the CoS queue number to which this entry belongs.
cwacCosbCurrentCellsDiscThres
1.3.6.1.4.1.351.150.16.1.2.1.1.2
Integer32 (0..2147483647)
This object indicates the threshold for cell discards for the current 15-min interval, above which alarm is generated.
cwacStatsAlarmStatus
1.3.6.1.4.1.351.150.16.1.2.1.1.3
Integer32 (0..2147483647)
This is a bitmap that shows the status of TCA(Threshold Crossing Alarm) of current queue. This bitmap is sent as part of the trap that is generated as part of TCA being raised.
Bit assignmed is as follows: ----------------------------
1 Cell discard 15 minute threshold was exceeded.
cwacValidIntervals
1.3.6.1.4.1.351.150.16.1.2.1.1.4
Integer32 (0..96)
The number of previous intervals for which valid data has been stored.
This table reflects interval statistics associated with each of the CoS queues. Entries in this table are automatically created when a new virtual interface is added.

cwacIntervalNumber
1.3.6.1.4.1.351.150.16.1.2.2.1.1
Integer32 (0..96)
A number used to uniquely identify per virtual interface CoS queue interval statistics. 0 is used to identify the current 15-minute interval. 1-96 identify the previous 24 hours of 15-minute interval buckets.
