| IfIndex | The ifIndex of the local frame relay interface. (IfIndex 155 corresponds to the frame relay portion of the local DTE interface at Port 2 of the Ethernet Base Module.) |
| FlowControl | Indicates whether or not rate enforcement will allow frames exceeding the CIR rate to be discarded during periods of heavy congestion. The default is disabled. |
| InfoRateAdjInterval | The number of seconds during which received frames are checked to see whether the FECN bit is set or cleared. The transmit rate is adjusted based on the number FECN bits set or cleared during this interval. The range is from 1 to 255 seconds. |
| ConsecutiveFrames | The number of consecutive frames that will be received with the BECN bit set before the transmit rate is reduced. The range is from 1 to 100 frames. |
| ConnectTime | The value of sysUpTime when this port was created. |
| TxLMI | The number of PVC LMI frames sent on this physical port (DLCI 0). |
| RxLMI | The number of PVC LMI frames received on this physical port (DLCI 0). |
| HeaderErrorRx | The number of frames received with an incomplete or missing address field. |
| InvalidDLCIRx | The number of frames received on an unassigned or invalid DLCI number. |
| ShortFramesRx | The number of short frames received. |
| LongFramesRx | The number of frames that were received that were longer than the WAN MTU size. |
| IgnoredFramesRx | The number of frames received that were ignored (meaning they contained an unknown error). |
| XIDExpirations | The number of XID TM21 timer expirations. (Valid only if MTU negotiation is enabled.) |
| TxExpirations | The status of PVC LMI (up or down). |
| PVCLMIStatus | The number of PVC LMI frames sent on this physical port (DLCI 0). |
| ActivePanlDlciSvc | Number of active PANL DLCI SVCs on this interface. |
| RxActivations | Number of activations received on this interface. |
| RxDeactivations | Number of deactivations received on this interface. |
| RxOkAcks | Number of OK ACK messages received on this interface. |
| RxErrAcks | Number of Error ACK messages received on this interface. |
| RxUnknowns | Number of Unknown messages received on this interface. |
| RxErrors | Number of Error messages received on this interface. |
| RxOctets | Number of data bytes received. |
| TxOctets | Number of data bytes sent. |
| TxThroughput | The transmission CIR expressed in bits/sec. |
| RxThroughput | The receive CIR expressed in bits/sec. |
| TxMaxFrameSize | The maximum transmission FR packet size expressed in bytes. |
| RxMaxFrameSize | The maximum receive FR packet size expressed in bytes. |
| RateEnforcement | The rate enforcement parameter for FR congestion management processing. |
| TxBc | The transmission committed burst size expressed in bits. |
| RxBc | The receive committed burst size expressed in bits. |
| TxBe | The transmission excess burst size expressed in bits. |
| RxBe | The receive excess burst size expressed in bits. |
| DataFrames | Total number of data frames on all assigned DLCIs. |
| DCDefNegMode | Defines the negotiation mode supported. |
| DCDefRetryTime | Timeout value for DC negotiation. |
| DCDefRetryCount | Retry counter for data compression negotiation. |
