jnxCosAtmVcScTable
The jnxCosAtmVcScTable, whose object identifier is jnxAtmCos 2, contains ATM-scheduler configuration parameters for each forwarding class within a specified VC.
 | Note: The schedulers referred in this MIB are specific to an ATM interface, and are different from the typical schedulers specified using the Class of Service configuration command-line interface (CLI). |
Each jnxCosAtmVcScEntry (object identifier is jnxCosAtmVcScTable 1) represents ATM-scheduler configuration parameters per forwarding class and per VC, and is indexed using ifIndex, atmVclVpi, and atmVclVci. Table 29 lists the ATM scheduler parameters as represented by a jnxCosAtmVcScEntry.
Table 29: jnxCosAtmVcScTable
Object | Object ID | Description |
|---|---|---|
jnxCosAtmVcScPriority | jnxCosAtmVcScEntry 1 | Represents the ATM scheduler priority for the queue associated with the specified forwarding class within the VC. |
jnxCosAtmVcScTxWeightType | jnxCosAtmVcScEntry 2 | Represents the ATM scheduler transmit-weight-type for the queue associated with the specified forwarding class inside the VC. The transmit-weight-type is represented either as the number of cells or as a percentage of the queue size. |
jnxCosAtmVcScTxWeight | jnxCosAtmVcScEntry 3 | Represents the transmit weight of the ATM scheduler for the queue associated with the specified forwarding class and the VC. jnxCosAtmVcScTxWeight is expressed either as the number of cells or as a percentage of the total VC bandwidth. The value of jnxCosAtmVcScTxWeightType.determines the unit used. |
jnxCosAtmVcScDpType | jnxCosAtmVcScEntry 4 | Shows the type of RED drop profile configured for the specified forwarding class within the VC. A scheduler can specify either linear or constant drop profile. A constant type drop profile (also known as EPD) specifies that all the cells should be dropped when the number of queued cells exceeds a threshold. A linear type drop profile specifies that only a percentage of cells be dropped based on the number of queued cells at any time. |
jnxCosAtmVcScLrdpQueueDepth | jnxCosAtmVcScEntry 5 | Represents the maximum queue size in cells, as specified by the linear RED drop profile associated with the specified forwarding class within the VC. This object is valid only when the value of the object jnxCosAtmVcScDpType is linearRed(0). |
jnxCosAtmVcScLrdpLowPlpThresh | jnxCosAtmVcScEntry 6 | Represents the threshold percentage of fill-level beyond which the low packet loss priority (PLP) packets belonging to the specified forwarding class within the VC are randomly dropped. This value is specified by the linear RED drop profile configuration. This object is valid only when the object jnxCosAtmVcScDpType is set to linearRed(0). |
jnxCosAtmVcScLrdpHighPlpThresh | jnxCosAtmVcScEntry 7 | Represents the threshold percentage of the fill level beyond which high PLP packets belonging to the specified forwarding class within the VC are randomly dropped. This value is specified by the linear RED drop profile configuration. This object is valid only when the object jnxCosAtmVcScDpType is set to linearRed(0). |
jnxCosAtmVcEpdThreshold | jnxCosAtmVcScEntry 8 | Shows the EPD drop threshold configured for the specified forwarding class within the VC. When the number of cells queued exceeds the value specified for this object, all the cells in the queue are dropped. This object is valid only when the jnxCosAtmVcScDpType object is set to epd(1). |
