What Is CISCO-GGSN-QOS-MIB?
CISCO-GGSN-QOS-MIB is a Cisco-proprietary MIB for the Gateway GPRS Support Node (GGSN), the node in a GPRS/UMTS mobile core network that connects the mobile packet-switched network to external data networks. It exposes Quality-of-Service configuration and statistics, including mappings between QoS classes and IP TOS/DSCP values, per-class bandwidth allocation and current usage, and traffic-shaping parameters such as mean throughput and deviation factors for premium versus best-effort traffic. From a monitoring standpoint it tracks the software/service performance of the GGSN's QoS engine — active PDP contexts per class, bandwidth consumption versus total allocated bandwidth, and throughput compliance — helping operators detect QoS congestion or misclassified traffic. It is closely tied to the broader CISCO-GGSN-MIB, which provides the base GGSN object model this QoS MIB extends. It is deployed on Cisco GGSN platforms within mobile operator GPRS/UMTS core networks. Engineers can download the CISCO-GGSN-QOS-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-GGSN-QOS-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.

- Cisco GGSN (Gateway GPRS Support Node)
Monitoring Examples
An operator polling cggsnQosCurrentPdps and cggsnQosCurrentUsedBandwidth alongside cggsnQosTotalBandwidthResrc can detect when a QoS class is approaching its allocated bandwidth ceiling, a precursor to dropped or throttled premium traffic. cggsnQosClassIpTosMapTable (via cggsnQosClass and cggsnQosMappedIpTos) lets an admin verify QoS classes are mapped to expected IP TOS markings, catching misconfiguration that would treat traffic at the wrong priority. cggsnQosPremiumMeanThroughput versus cggsnQosNormalMeanThroughput gives a quick check of whether premium subscribers are actually receiving better throughput than best-effort ones.
What Can Be Monitored
- QoS class to IP TOS mapping
- current PDP contexts per QoS class
- bandwidth resource usage vs. total allocation
- premium vs. best-effort mean throughput
- throughput deviation factor

How to Use in IPNetwork Monitor
Example using cggsnQosCurrentUsedBandwidth OID:
Select a Cisco GGSN (Gateway GPRS Support Node) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cggsnQosCurrentUsedBandwidth into the Find box to locate it in the OID tree, then select it and click OK. The current amount of bandwidth resource used on the GGSN. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the value drifts significantly from its normal baseline (in bits/sec), since an unexpected change often points to a real underlying issue. Click Finish to create the monitor; you can adjust any parameter later.

| cggsnQosMIB | 1.3.6.1.4.1.9.9.241 | This MIB module manages the Quality of Service parameters of GGSN in a GPRS system. GGSN is the Gateway GPRS Support Node in the GPRS architecture. It provides interworking of GPRS network with external packet-switched networks - PDNs or other data networks. The following diagram illustrates a simplified GPRS logical architecture with the name of inter-node interface: +---------------------------------------------+ | +======+ a PLMN | | | SGSN | | | +======+ | | | | | Gn | | | | |+====+ +====+ +=====+ +======+ +======+ | +===+ || TE |-R-| MT |-| BSS |-| SGSN |-Gn-| GGSN |-|-Gi-|PDN| |+====+ +====+ +=====+ +======+ +======+ | +===+ | | | | | | +----------------------------------------|----+ Gp | +-----------------------------+ | +====+ +=====+ +======+ | | | MS |---| BSS |---| SGSN | | | +====+ +=====+ +======+ | | | | other PLMN | +-----------------------------+ A PDP Context is an information set maintained by MS and GSNs which describes the mobile wireless service call or session. Three types of QoS mapping method are supported on GGSN: canonical, delay and UMTS. Canonical QoS mapping consists of Best Effort, Normal and Premium QoS classes. Delay QoS mapping consists of four classes: delay1, delay2, delay3 and delay-besteffort. UMTS QoS has the following traffic classes: signalling, conversational, streaming, interactive and background. UMTS QoS is based on differentiated services network model. A QoS Profile is associated with each PDP context which defines multiple attributes like precedence, delay, reliability, peak throughput, mean throughput and traffic class. Based on the precedence, delay and mean throughput an user is classified into different canonical and delay QoS classes . Based on delay, jitter, bandwidth and reliability user is classified into the UMTS traffic classes. In GGSN, the QoS remapping mechanism is that, for uplink traffic, the GGSN remaps the TOS in the user traffic before forwarding the packet to the Gi interface and for downlink traffic, the GGSN will only setup the TOS for the IP header for the Tunnel, not the IP header for user traffic. Traffic from MS to PDN is considered as uplink and the reverse is considered as downlink traffic.

DS architecture is based on number of functional elements, one of which is PHB. PHBs specify queuing, queue management and scheduling characteristics that allow a means of allocating buffer and bandwidth resources at each node among the competing traffic streams. The various DS PHBs include: signalling - signallingClass(1) The signalling class PHB is only used for the UMTS signalling messages. This DS PHB does not apply to any other IP data packets. expedited forwarding - efClass(2) The expedited forwarding PHB is used for providing a low loss, low latency, low jitter, assured bandwidth, end-to-end service through the DS domains. Such a service appears to the endpoints like a point-to-point connection, or a virtual leased line. assured forwarding - afClass(3-6) The assured forwarding PHB provides a means for a provider DS domain to offer different levels of delivery assurances for packets received from a customer DS domain. Four assured forwarding classes: afClass1, afClass2, afClass3 and afClass4 are defined, where each AF class is in each DS node allocated a certain amouont of forwarding resoources(buffer space and bandwidth). IP packets are assigned into one or more of these classes, according to the subscribed service. Within each class the packets are marked by a mobile subscriber, or by the provider DS domain, with one of the three possible drop precedence values. In case of congestion, the drop precedence of a packet determines the relative importance of a packet within the class. Packets in one class are forwarded independently of the packets in another class. best effort - bestEffort(7) This is the default PHB. The packets of this aggregate are forwarded on an output link whenever the link is not required to satisfy any other PHB. |

For the IMS PDP context, this parameter is taken from authorized QoS obtained from PDF. The SNMP entity creates a conceptual row when the user configures the MBR/GBR for a particular traffic class with either uplink or downlink traffic type and there must be a corresponding conceptual row existing in cggsnUmtsQosCacPolicyTable. The SNMP entity deletes the conceptual row(s), when the user deletes the MBR/GBR configuration or the corresponding conceptual row is deleted from cggsnUmtsQosCacPolicyTable. However, if some PDP context is active in the APN using this policy, then the conceptual row(s) cannot be deleted. The SNMP entity modifies the conceptual row, when the user changes the MBR/GBR value or the optional reject parameter. However, if any PDP context is active in the APN using this policy, then the MBR/GBR value can be changed to higher than the previously configured. | |

| cggsnUmtsQosCacBWPoolTable | 1.3.6.1.4.1.9.9.241.1.3.4.5 | not-accessible | This table defines allocation of virtual bandwidth pool for the traffic classes. Basically there are two types of bandwidth pool, Physical & Virtual. Physical bandwidth is the egress interface bandwidth. It is not supported and will not be explained more. Virtual bandwidth is user defined bandwidth. Virtual bandwidth provides an easy and flexible way to implement bandwidth pool for call admission control to avoid physical bandwidth limitations. In contrast to per-interface based physical bandwidth management, Virtual bandwidth management is per-APN based, that is, each APN has its own pool to admit request. To use this type of bandwidth, user needs to make assumption of what interface type and total bandwidth of Gi and Gn in both directions to allocate bandwidth for each class. The SNMP entity creates a conceptual row when the user configures the bandwidth pool with some bandwidth value in the range described in cggsnUmtsQosCacBWPoolBWVal. The SNMP entity deletes the conceptual row, when the user deletes the bandwidth pool. However, if the bandwidth pool is associated with an APN or if bandwidth is currently been utilized, then the conceptual row cannot be deleted. The SNMP entity modifies the conceptual row, when the user changes the bandwidth value. However, if any PDP context is active in the APN using this pool, then the bandwidth value can be changed to higher than the previously configured. | |
| cggsnUmtsQosCacBWPoolEntry | 1.3.6.1.4.1.9.9.241.1.3.4.5.1 | not-accessible | Each entry in this table holds the total bandwidth that this pool provides and the corresponding allocation to the traffic classes. | |

| cggsnQosBWPoolTrafClassTable | 1.3.6.1.4.1.9.9.241.1.3.4.6 | not-accessible | This table is the sub table of cggsnUmtsQosCacBWPoolTable. This contains all the traffic class bandwidth allocation in percentage or absolute value. The total value of the bandwidth allocated for different traffic class per pool must not exceed 100 percent or the absolute value (4294967295). The SNMP entity creates a conceptual row when the user configures the bandwidth allocation for the traffic class defined in cggsnQosBWPoolTrafClass and if the corresponding conceptual row is present in cggsnUmtsQosCacBWPoolTable. The SNMP entity deletes the conceptual row(s) when the user unconfigures the bandwidth allocation for the traffic class or the corresponding conceptual row is deleted from cggsnUmtsQosCacBWPoolTable. However, if there are active PDP in the APN using this pool, then the conceptual row cannot be deleted. The SNMP entity modifies the conceptual row when the user changes the bandwidth allocation for a traffic class. However, if there are active PDPs in the APN using this pool, then only value greater than previous allocation is accepted. | |
