What Is CADANT-DQOS-GATE-MIB?
CADANT-DQOS-GATE-MIB is an ARRIS/Cadant proprietary MIB for the Cadant C4 CMTS (cable modem termination system), covering the PacketCable Dynamic Quality-of-Service (DQoS) "Gate" client used for per-flow service authorization in COPS-based cable telephony/multimedia deployments. It exposes configuration and state data for DQoS gates, including subscriber ID and classifier fields (protocol, source/destination IP and port) used to match traffic flows, along with gate commit and resource-reservation controls. Monitoring-wise it is oriented toward service and session software status rather than raw hardware health: operators track gate resource IDs and commit state to confirm that QoS reservations for VoIP/multimedia calls are being correctly authorized and enforced. It explicitly depends on the standard COPS protocol objects defined in RFC 2940, since the DQoS gate client rides on top of COPS signaling. It is deployed in cable-operator head-ends running Cadant CMTS equipment that supports PacketCable-based voice and multimedia services to residential subscribers. Engineers can download the CADANT-DQOS-GATE-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CADANT-DQOS-GATE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- ARRIS/Cadant C4 CMTS (cable modem termination system)
Monitoring Examples
An operator would poll cadDQoSGateTable/cadDQoSGateEntry keyed by cadDQoSGateId to inspect cadDQoSGateSubscriberID together with the classifier fields cadDQoSGateClassifierSrcIP/DestIP and cadDQoSGateClassifierSrcPort/DestPort, confirming a subscriber's voice flow has an active, correctly matched QoS gate. If cadDQoSMgmtGateCommitNotAllowed is set or cadDQoSGateResourceID fails to populate, that flags a failed resource reservation preventing the call's QoS from being honored. The cadDQoSGateAutoCommit setting also reveals whether gates are auto-committed or awaiting external COPS policy decisions.
What Can Be Monitored
- DQoS gate subscriber ID
- flow classifier (source/destination IP and port)
- gate resource ID / commit status
- gate auto-commit setting
- gate resource reservation state

|---|---|---|---|---|
| U32 cadDQoSAuthFlowSpecBucketDepthb | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3.1.2 | Unsigned32 | read-write | Parameter 'b' in TSpec leaky bucket description. The token bucket size controls the maximum amount of data that the flow can send at the peak rate. More formally, if the token bucket size is 'b' and the token bucket rate is 'r', over any arbitrarily chosen interval T in the life of the flow, the amount of data that the flow sends cannot have exceeded b + (r * T) bytes. The bucket size limits how many credits the flow may store. When the bucket is full, new credits are discarded. |
| U32 cadDQoSAuthFlowSpecBucketRater | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3.1.3 | Unsigned32 | read-write | Parameter 'r' in TSpec leaky bucket description. The token bucket rate is the rate at which credits are placed into an imaginary token bucket. For each flow, a separate bucket is maintained. To send a packet over the flow, a host must remove a number of credits equal to the size of the packet from the token bucket. If there are not enough credits, the host must wait until enough credits accumulate in the bucket. |
| cadDQoSAuthFlowSpecEntry | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3.1 | not-accessible | This entry contains one row in the table. | |
| U32 cadDQoSAuthFlowSpecIdx | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3.1.1 | Unsigned32 | not-accessible | Index of flow specification within Gate |
| U32 cadDQoSAuthFlowSpecMaxPktSizeM | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3.1.6 | Unsigned32 | read-write | Parameter 'M' in TSpec leaky bucket description. This is the maximum packet size (including IP and header layers) that can be generated by the source. |
| U32 cadDQoSAuthFlowSpecMinPolicedUnitm | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3.1.5 | Unsigned32 | read-write | Parameter 'm' in TSpec leaky bucket description. All IP datagrams less than size 'm' will be counted, when policed and tested for conformance to the TSpec, as being of size 'm'. This is the smallest size packet that the source will generate. |
| U32 cadDQoSAuthFlowSpecPeakRatep | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3.1.4 | Unsigned32 | read-write | Parameter 'p' in TSpec leaky bucket description. The maximum transmission rate limits how fast packets may be sent back to back from the host. Consider that if the token bucket is full, it is possible for the flow to send a series of back-to-back packets equal to the size of the token bucket. At all times, 'p' MUST be greater than or equal to the token bucket rate, 'r'. |
| U32 cadDQoSAuthFlowSpecReservedRateR | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3.1.7 | Unsigned32 | read-write | Parameter 'R' in RSpec. A service accepting an invocation request may be thought of as entering into a contract to provide the service described by the RSpec as long as the flow's traffic continues to be described by the TSpec. This is the policed, reserved transmission flow rate toward the destination. |
| U32 cadDQoSAuthFlowSpecSlackTermS | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3.1.8 | Unsigned32 | read-write | Parameter 'S' in RSpec. This is the maximum amount of slack (in microseconds) that can be added to the inherent delay to produce an acceptable delay bound. |
| ADR cadDQoSAuthFlowSpecSubscriberID | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3.1.9 | InetAddressIPv4or6 | read-write | The Subscriber-ID identifies the subscriber (cable modem) for this service request. Its main use is to prevent various denial-of-service attacks. |
| cadDQoSAuthFlowSpecTable | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.3 | not-accessible | The Authorized flow specification describes the envelope that the data flow is allowed to use. Issues such as subscribed level of service, account state, etc. are components that may affect the authorized envelope. There is a one-to-many mapping between Gates and authorized flow specifications. However, only one authorized flow spec may be in effect at a time for each Gate. | |

| U32 cadDQoSGateId | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.1.1.1 | Unsigned32 | not-accessible | The GateID is 32 bit identifier that is allocated from the local space at the CMTS where the Gate resides. Up to two gates MAY share the same Gate-ID. Typically, a Gate-ID will identify a single upstream flow and a single downstream flow, and correspond to a single Multi-media session. All gates assigned the same Gate-ID by the CMTS MUST transition together through the cadDQoSGateState. |
| T/F cadDQoSGateReserveRequest | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.1.1.22 | TruthValue | read-write | Flag indicating that a reservation request has been received for this gate. |

| U32 cadDQoSGateTimerT7 | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.1.1.20 | Unsigned32 | read-write | The CMTS MUST set the Timeout for Admitted QoS Parameters for the service flow to the value specified by this timer. The timeout for Admitted QoS Parameters limits the period of time that the CMTS must hold resources for a service flow's Admitted QoS Parameter Set while they are in excess of its Active QoS Parameter Set. See Appendix C, section C.2.2.5.7 of the DOCSIS RFI for more details on the use of this timer. In order to allow the EMTA to refresh this timer, the CMTS MUST inform the EMTA of the Timeout for Admitted QoS Parameters value in the response (i.e. in the DSA-RSP) to the EMTA's reservation request. The recommended default value of this timer is 200 seconds. |
| U32 cadDQoSGateTimerT8 | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.1.1.21 | Unsigned32 | read-write | The CMTS MUST set the Timeout for Active QoS Parameters for the service flow to the value specified by this timer. The Timeout for Active QoS Parameters limits the period of time resources remain unused on an active service flow. See Appendix C, section C.2.2.5.6 of the DOCSIS RFI for more details on the use of this timer. In order to allow the EMTA to refresh this timer, the CMTS MUST inform the EMTA of the Timeout for Active QoS Parameters value in the response (i.e. in the DSA-RSP) to the EMTA's reservation request. The default value of this timer is 0, which instructs the CMTS not to poll for activity on the service flow. |

| U32 cadDQoSSFID | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.1.1.28 | Unsigned32 | read-write | Service flow ID for this gate ID and flow direction |
| PCR cadDQoSTearFlows | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.1.1.24 | PCReasonCode | read-write | Enumeration indicating whether the Flows for this Gate are to be torn down. If set to anything other than noReason by the CAM, then the flows have been torn down for the reason specified and the gate must update itself. If set to anything other than noReason by the gate state machine, then it is a command to the CAM to tear down and delete the flows. |
| U32 cadDQoSTimerT0 | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.4 | Unsigned32 | read-write | This timer is implemented in the CMTS in the Gate state machine, and limits the period of time that a gate may be allocated without the gate parameters being set. This enables the CMTS to recover the gate-ID resources when the Call Management System fails to complete the signaling sequence for a new session. The default value of this timer is 30 seconds. This timer has a range of 1 to 60 seconds. |
| U32 cadDQoSTimerT1 | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.5 | Unsigned32 | read-write | This timer is implemented in the CMTS in the Gate state machine, and limits the period of time that may elapse between the authorization and a commit is performed. This timer is started whenever a Gate is established. This timer is reset whenever a Commit operation is performed on the resources authorized by the gate. Timer-T1 MUST be set to the value given in the GATE-SET message. If the value given in the GATE-SET message is zero, then Timer-T1 MUST be set to a provisionable default value. The default value of this timer is 250 seconds. |
| U32 cadDQoSTimerT2 | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.6 | Unsigned32 | read-write | This timer is implemented in the CMTS in the Gate state machine, and limits the time in the transient states of gate coordination. This timer is long enough to accommodate loss and retransmission of Gate coordination messages, but is short enough to not allow significant theft of service. Timer-T2 MUST be set to the value given in the GATE-SET message. If the value given in the GATE-SET message is zero, then Timer-T2 MUST be set to a provisionable default value. The default value of this default is 2 seconds. |
| U32 cadDQoSTimerT3 | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.7 | Unsigned32 | read-write | This timer is implemented in the MTA or CMTS in the handling of RSVP reservations. It controls the total time that can elapse before the RSVP retransmit process gives up without receiving an acknowledgement in the presence of network loss. It is short enough to recover quickly from lost messages and not significantly impact the post-dial delay, but is long enough to allow the CMTS to acknowledge the request and all intermediate routers in the customer network. The default value of this timer is 4 seconds. |
| U32 cadDQoSTimerT4 | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.8 | Unsigned32 | read-write | This timer is implemented in the MTA in the handling of COMMIT messages. It controls the retransmission of COMMIT messages that may have been lost by the network. It is short enough to recover quickly from lost commit requests and not significantly impact the post-pickup delay, but is long enough to allow processing of the COMMIT request at the CMTS. The default value of this timer is 500ms. |
| U32 cadDQoSTimerT5 | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.9 | Unsigned32 | read-write | This timer is implemented in the CMTS (and CMTS-proxy) in the gate coordination processing. It controls the retransmission of GATE-OPEN and GATE-CLOSE messages that may have been lost by the network. It is short enough to recover quickly from lost gate coordination messages, but long enough to allow processing of the gate coordination message at the CMTS or CMTS-proxy. This timer interacts in the case of GATE-OPEN with Timer-T2, and SHOULD be significantly smaller than Timer-T2. The default value of this timer is 500ms. |
| U32 cadDQoSTimerT6 | 1.3.6.1.4.1.4998.1.1.115.1.2.1.1.10 | Unsigned32 | read-write | This timer is implemented in the MTA or CMTS in the handling of RSVP reservations. It controls the initial delay used by the RSVP retransmit procedure. The default value of this timer is 500ms. |
