Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is CISCO-WAN-MG-MIB?
CISCO-WAN-MG-MIB is a Cisco vendor module for managing Media Gateways (MGs) — devices that convert PSTN voice circuits to IP/VoIP traffic under control of a Media Gateway Controller (MGC) using protocols like MGCP. It exposes the gateway's administrative state and state-control objects, a graceful-shutdown grace timer, a table of supported signaling protocols, and a table of associated MGCs with a configured maximum concurrent-MGC limit. Its monitoring role is centered on software/hardware status of the voice gateway — whether it is in service, shutting down gracefully, and properly registered to its controller(s) — which is critical for detecting call-setup failures caused by a lost MGC session or an unexpected administrative shutdown. It depends on the surrounding MGCP/media-gateway control framework (RFC 3435-era MGCP concepts) referenced in its terminology. Loading the module into a CISCO-WAN-MG-MIB MIB Browser makes it easy to walk mgAdministrativeState and the mgcTable interactively, and it is deployed in carrier and enterprise VoIP gateway environments bridging traditional PSTN trunks to IP telephony infrastructure.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-WAN-MG-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
- Cisco WAN Media Gateway (VoIP-to-PSTN voice gateway)
Monitoring Examples
An admin would poll mgAdministrativeState and mgAdministrativeStateControl for a given mgName to confirm the gateway is in service, checking mgShutdownGraceTime if a graceful shutdown is in progress. They would also inspect mgcTable/mgcEntry against maxConcurrentMgcs to verify the gateway still has an active mgcNumber controller session, since a lost MGC association would explain calls failing to set up through that gateway.
What Can Be Monitored
- media gateway administrative state
- graceful shutdown timer
- supported signaling protocols (e.g. MGCP)
- associated media gateway controller(s)
- concurrent MGC session count

| INT mgAdministrativeState | 1.3.6.1.4.1.351.150.10.1.1.2 | INTEGER | read-only | This object indicates the current admin state of the Media Gateway. The possible admin states are: 'inService' - The MG is ready to provide service. In this state, the MG will respond to connection control requests, emit autonomous messages to MGCs as applicable, etc. 'commandedOutOfService' - The MG does not provide service and all resources have been released. In this state, the MG will not respond to any connection control requests or emit autonomous messages. 'pendingOutOfService' - This is a transitional state prior to going 'commandedOutOfService'. In this state the MG provides service but does not accept new service requests (i.e. creation of connections) will transition to 'commandedOutOfService' according to 'mgShutdownGraceTime'. |
| INT mgAdministrativeStateControl | 1.3.6.1.4.1.351.150.10.1.1.3 | INTEGER | read-write | This control object is used to change the service state of the MG from 'inService' to 'commandedOutOfService' and from 'commandedOutOfService' to 'inService'. The resulting service state of the gateway is represented by 'mgAdministrativeState'. If set, this object triggers the following: 'inService': Transition 'mgAdministrativeState' to 'inService'. In the course, the MG's MGCs may get notified of this transition, e.g. in the case of MGCP through emission of RSIPs to registered call agents according to policy. 'forcefulOutOfService': Take the gateway out-of-service forcefully. This releases any resources at the MG. In the course, the MGCs may get notified of this transition, e.g. in the case of MGCP through emission of RSIPs to registered call agents according to policy. 'gracefulOutOfService': Take the gateway out-of-service gracefully. If there are no resources existing, 'mgAdministrative' transitions to 'commandedOutOfService' immediately. If resources exist, 'mgAdministrativeState' transitions to 'pendingOutOfService' thus initiating a graceful shutdown. In the course, the MGs MGCs may get notified of this transition, e.g. in the case of MGCP through emission of RSIPs to registered call agents according to policy. |
| INT mgcAssociationState | 1.3.6.1.4.1.351.150.10.1.2.1.1.4 | INTEGER | read-only | Represents the state of the association between the MG and the MGC. The possible values are: 'mgcUnassociated' : MG and MGC are not associated. For example, in the case where MGCP is the coordination protocol, it means no subscription to autonomous messages such as RSIP but control requests would be answered. 'mgcAssociated' : MG and MGC are associated. E.g. in the case where MGC is the coordination protocol, it means MGC is subscribed to autonomous messages such as RSIP. 'mgcAssociatedCommLoss' : Associated but MGC unreachable. This object is being moved to the mgcRedundancyGrpParamTable. This object is deprecated because the association state is defined per MGC redundancy group, rather than per MGC. |
| INT mgcAssociationStateControl | 1.3.6.1.4.1.351.150.10.1.2.1.1.5 | INTEGER | read-create | Used to control the association state, as represented by mgcAssociationState. The possible value for a set operation on this object are: 'mgcUnassociate': Transition from any state to 'mgcUnassociated'. If registered, MG will initiate deregistration. 'mgcAssociate' : Transition to 'mgcAssociated'. If applicable, MG will register with MGC. If MGCP is the coordination protocol, MG will send RSIP. If MG cannot establish communication, it will subsequently transition into 'mgcAssociatedCommLoss' for the 'mgcAssociationState' object. If MG is already associated with MGC, no transition will take place and mgcAssociationState shall not change. 'mgcClear' : No action will be taken. This means that the Media Gateway will not initiate any association/unassociation. This object is being moved to the mgcRedundancyGrpParamTable. This object is deprecated because the association state control is defined per MGC redundancy group, rather than per MGC. |
| I32 mgcCommLossUnassociationTimeout | 1.3.6.1.4.1.351.150.10.1.2.1.1.7 | Integer32 | read-create | Indicates how long, in seconds, upon detection of a communication loss, subscriptions to autonomous notifications (such as notification requests and RSIPs in the case of MGCP) remain valid and communications will be reattempted for an MGC in 'mgcAssociatedCommLoss' state. A value of -1 indicates that the MGC may remain in 'mgcAssociatedCommLoss' state indefinitely. A value of 0 indicates that the MGC transitions into 'mgcUnassociated' state immediately. This object may not always be configurable, i.e. be read only in some agent implementations. An MG implementation may not support differentiation of the timeout between associations. In such an event, any modification to the value for one MGC will take effect globally. |
| T/F mgcDnsResolution | 1.3.6.1.4.1.351.150.10.1.2.1.1.3 | TruthValue | read-only | Indicates how the MG resolves the IP address of the MGC. 'true(1)' - the resolution is done using an external DNS server. 'false(2)' - the resolution is done using mgcResolutionTable. |
| INT mgcDnsResolutionFlag | 1.3.6.1.4.1.351.150.10.1.5.1.1.7 | INTEGER | read-only | All entries statically configured by the customer (i.e. all entries in the top half of the table) will have the flag set to 'internal'. All IP addresses obtained due to external resolution of the domain name (that is, entries in the bottom half of the table) will have this flag set to 'external'. |
| mgcEntry | 1.3.6.1.4.1.351.150.10.1.2.1.1 | not-accessible | Represents an individual table entry in mgcTable. | |
| STR mgcName | 1.3.6.1.4.1.351.150.10.1.2.1.1.2 | SnmpAdminString | read-create | Denotes the name of the media gateway controller. This corresponds to a domain name under which the MGC could also be registered in a DNS. Once the row has become active, this value may not be modified. |
| I32 mgcNumber | 1.3.6.1.4.1.351.150.10.1.2.1.1.1 | Integer32 | not-accessible | Serves as index to this table. |
| mgcProtocolEntry | 1.3.6.1.4.1.351.150.10.1.2.2.1 | not-accessible | Represents an individual table entry in mgcProtocolTable. mgcNumber references the media gateway controller, constituting a foreign key into mgcTable and adapting the value of mgcNumber of that MGC. mgProtocolNumber references the protocol, reflecting the mgProtocolNumber from the mgSupportedProtocolTable. When active, it is expected that mgcNumber and mgcProtocolNumber contain valid values that maintain referential integrity, i.e. constitute valid foreign keys into mgcTable and mgSupportedProtocolTable respectively. The attempt to create a row that would violate referential integrity shall be rejected. With support for multiple MGC redundancy groups, the protocols will be defined per MGC redundancy group rather than per MGC. | |
| ROW mgcProtocolRowStatus | 1.3.6.1.4.1.351.150.10.1.2.2.1.1 | RowStatus | read-create | Controls the creation and deletion of a table entry. An entry may be created using the 'createAndGo' option. When the row is successfully created, the RowStatus would be set to 'active' by the agent. An entry may be deleted by setting the RowStatus to 'destroy'. Other options such as `createAndWait', 'notInService', 'notReady' will not be used. With support for multiple MGC redundancy groups, the protocols will be defined per MGC redundancy group rather than per MGC. |
| mgcProtocolTable | 1.3.6.1.4.1.351.150.10.1.2.2 | not-accessible | This table contains information about which protocols are being used in a particular association between the gateway and the MGCs. Because there may be a number of different protocols in use for a particular control association between the gateway and an MGC, this information is kept in a separate table rather than being included in mgcTable. In effect, it constitutes a relationship between mgcTable and mgSupportedProtocolTable. With support for multiple MGC redundancy groups, the protocols will be defined per MGC redundancy group rather than per MGC. A new table mgcRedundancyGrpProtocolTable is introduced. | |
| INT mgcResolutionCommState | 1.3.6.1.4.1.351.150.10.1.5.1.1.4 | INTEGER | read-only | Indicates whether the address is the one currently applied for communications with the system of that name. 'csActive' - name resolves to that IP address 'csInactive' - IP address currently not in use On creation of the row, this value will be 'csInactive', although it may transition immediately to active, triggering the notification of 'mgcCommStateActive' specified in CISCO-VISM-TRAPS-MIB. |
| mgcResolutionEntry | 1.3.6.1.4.1.351.150.10.1.5.1.1 | not-accessible | Represents an individual table entry in mgcResolutionTable. | |
| I32 mgcResolutionIndex | 1.3.6.1.4.1.351.150.10.1.5.1.1.1 | Integer32 | not-accessible | Serves as index to this table. The table will be divided into two, index 1 to 88 will be used by the user and index 89 to 176 will be used by the VDNS to fill in the externally resolved IP address. |
| IP mgcResolutionIpAddress | 1.3.6.1.4.1.351.150.10.1.5.1.1.3 | IpAddress | read-create | Denotes the IP address of the entity. Once the row has become active, this value may not be changed. To change the IP address, an entry will have to be removed and a new entry will have to be added. |
| STR mgcResolutionName | 1.3.6.1.4.1.351.150.10.1.5.1.1.2 | SnmpAdminString | read-create | Denotes the name of the entity (MGC and/or NE) whose address is to be resolved. Once the row has become active, this value may not be changed. |
| I32 mgcResolutionPreference | 1.3.6.1.4.1.351.150.10.1.5.1.1.5 | Integer32 | read-create | This object can be used by the MG in the selection of an IP address if multiple IP addresses are available for the same name. This object cannot be modified after this entry is created. It has to be unique among various IP addresses of a same domain name. In which case the IP address associated with mgcResolutionPreference 1 would be selected over the IP address associated with mgcResolutionPreference 2. |
| ROW mgcResolutionRowStatus | 1.3.6.1.4.1.351.150.10.1.5.1.1.6 | RowStatus | read-create | Controls the creation and deletion of a table entry. An entry may be created using the 'createAndGo' option. mgcResolutionIndex, mgcResolutionName, mgcResolutionIpAddress, and mgcResolutionPreference should be provided when creating an entry. mgcResolutionIndex can be 1 - 88. Entries with index 89 - 176 will be implicitly added when VDNS resolves IP addresses of domain servers. Usually maximum 8 IP addresses can be added to one mgcName. For external DNS server only 3 IP addresses with the highest will be used. Before creating an entry in this table one entry should already been created in mgDomainNameTable with the same name as mgcResolutionName. When the row is successfully created, the RowStatus would be set to 'active' by the agent. An entry may be deleted by setting the RowStatus to 'destroy'. Only mgcResolutionIndex should be provided to delete an entry. The last IP within 1 - 88 should not be deleted if the mgcResolutionName is still configured for MGC, tftp server, external DNS server, PRI backhaul session group or announcement server and there is no external resolved IP (entry 89 - 176) for this domain name. Other options such as `createAndWait', 'notInService', 'notReady' will not be used. |
| mgcResolutionTable | 1.3.6.1.4.1.351.150.10.1.5.1 | not-accessible | This table provides the name to IP address mapping for each of the MGCs, external DNS server, tftp server and announcement server. It also stores the IP addresses of external resolved domain name. Several addresses may be associated with a single name. | |
| ROW mgcRowStatus | 1.3.6.1.4.1.351.150.10.1.2.1.1.8 | RowStatus | read-create | Controls the creation and deletion of a table entry. An entry may be created using the 'createAndGo' option. When the row is successfully created, the RowStatus would be set to 'active' by the agent. An entry may be deleted by setting the RowStatus to 'destroy'. Other options such as `createAndWait', 'notInService', 'notReady' will not be used. For creating the row, a value for mgcName must be provided. This mgcName should be already added in mgDomainName table and at least 1 IP should associated to this mgcName. To all other objects, defaults defined by the agent implementation may apply. Deletion of a row with mgcAssociationState other than unassociated shall be rejected. |
| mgcTable | 1.3.6.1.4.1.351.150.10.1.2.1 | not-accessible | This is a table which contains information about the individual MGCs. | |
| INT mgcUnassociationPolicy | 1.3.6.1.4.1.351.150.10.1.2.1.1.6 | INTEGER | read-create | Indicates what MG will do when mgcAssociationState transitions to unassociated. 'mgcNoAction' : indicates that MG will take no further action. In particular, no resources will be released nor connections be flushed. 'mgcRelease' : indicates that upon unassociation, the MG will release all resources and flush all connections. This object may not always be configurable, i.e. be read only in some agent implementations. In these cases, mgcNoAction shall be supported as the default value. |
| INT mgDnsResolutionType | 1.3.6.1.4.1.351.150.10.1.6.1.1.3 | INTEGER | read-create | This object determines the kind of DNS resolution to be applied for a particular domain name. 'internalOnly' means that the gateway will not try to resolve the IP address for this domain name using external DNS. The IP address/es for this domain name will be obtained from the first half of mgcResolutionTable, which are added by the user. 'externalOnly' means the IP address for this domain name will be resolved externally using external DNS. 'internalFirst' means the first preference will be given to statically provisioned IP address/es, followed the IP address/es resolved using external DNS. 'externalFirst' means the first preference will be given to IP addresses resolved using external DNS followed by statically provisioned IP addresses. This object can be modified when mgDomainNameRowStatus is active except that if the mgDomainName refers to external DNS server then this object cannot be changed. The request to change from 'internalOnly' to other types will be rejected if external DNS server is 'NULL'. The external DNS server can be set to 'NULL' through the object vismExtDnsServerDn in CISCO-VISM-MODULE-MIB. When user change this object to 'internalOnly' then all the externally resolved IP addresses should be implicitly deleted from mgcResolutionTable. |
| STR mgDomainName | 1.3.6.1.4.1.351.150.10.1.6.1.1.2 | SnmpAdminString | read-create | This object denotes the domain name of MGCs, tftp server, external DNS server or announcement server. Once the row has become active, this value may not be changed. |
| mgDomainNameEntry | 1.3.6.1.4.1.351.150.10.1.6.1.1 | not-accessible | Represents an individual table entry in mgDomainNameTable. | |
| I32 mgDomainNameIndex | 1.3.6.1.4.1.351.150.10.1.6.1.1.1 | Integer32 | not-accessible | This object serves as index to this table. |
| ROW mgDomainNameRowStatus | 1.3.6.1.4.1.351.150.10.1.6.1.1.4 | RowStatus | read-create | Controls the creation and deletion and of a table entry. An entry may be created using the 'createAndGo' option. User can only set mgDnsResolutionType to 'internalOnly'. The request to set an entry with mgDnsResolutionType of 'externalOnly', 'internalFirst' or 'externalFirst' would be rejected if the external DNS server is 'NULL'. When the row is successfully created, the RowStatus would be set to 'active' by the agent. An entry may be deleted by setting the RowStatus to 'destroy'. The deletion of an entry will be rejected if there is still reference to this domain name. For example, it cannot be deleted if it is configured as MGC, tftp server, external DNS server or announcement server. Also user added IPs should already been deleted. After delete the domain name externally resolved IPs are purged implicitly. The request to change from 'internalOnly' to other types will be rejected if external DNS server is 'NULL'. Other options such as `createAndWait', 'notInService', 'notReady' will not be used. |
| mgDomainNameTable | 1.3.6.1.4.1.351.150.10.1.6.1 | not-accessible | This table provides the domain names that are configured by users. The domain names could refer to Call Agents, tftp server for CAS file download, external DNS server or announcement server. | |
| I32 mgEndpointChannelMap | 1.3.6.1.4.1.351.150.10.1.3.1.1.6 | Integer32 | read-create | Bit map of DS0s used by the endpoint. Bit positions set to '1' represent DS0s used by the endpoint. The Bit position corresponds to the DS0 number. Once the row has become active, this value may not be changed. |
| INT mgEndpointCreationPolicy | 1.3.6.1.4.1.351.150.10.1.3.2 | INTEGER | read-write | Identifies whether the MG creates endpoints for connections involving single channels (e.g. DS0s) dynamically upon receipt of a create connection request in the control protocol, or whether the endpoints have to be configured statically. This does not apply for endpoints involving several channels (such as nx64) which will in general be configured statically. 'dynamic': Endpoint created dynamically if not already existing. 'strictDynamic': Endpoint created dynamically; connection requests must not refer to preexisting endpoint. 'static': Endpoint statically provisioned. This object will in general not be configurable, i.e. be read only in most agent implementations. |
| mgEndpointEntry | 1.3.6.1.4.1.351.150.10.1.3.1.1 | not-accessible | Represents an individual table entry in mgEndpointTable. | |
| mgEndpointExtEntry | 1.3.6.1.4.1.351.150.10.1.3.3.1 | not-accessible | Each entry represents a media gateway endpoint interface. | |
| mgEndpointExtTable | 1.3.6.1.4.1.351.150.10.1.3.3 | not-accessible | This table extends the mgEndpointTable. Objects that do not directly describe the endpoint but extend the rules to configure the mgEndpointTable can be added to this table. Each table entry describes an instance of an endpoint on a media gateway. | |
| I32 mgEndpointLineNumber | 1.3.6.1.4.1.351.150.10.1.3.1.1.2 | Integer32 | read-create | Identifies the DS1 line. Generally, this will correspond to the ifIndex of the physical interface terminating the line. Once the row has become active, this value may not be changed. |
| STR mgEndpointName | 1.3.6.1.4.1.351.150.10.1.3.1.1.3 | SnmpAdminString | read-create | Identifies endpoint as it is known by the MGC. If MG and MGC use a mutually agreed upon convention, this may be supplied by the agent, i.e. be read-only. |
| I32 mgEndpointNumber | 1.3.6.1.4.1.351.150.10.1.3.1.1.1 | Integer32 | not-accessible | Identifies endpoint as it is known by the NE. The endpoint number is unique for the entire MG and ranges from 1 to the maximum number of endpoints that the MG can support. |
| U32 mgEndpointRepetition | 1.3.6.1.4.1.351.150.10.1.3.3.1.1 | Unsigned32 | read-create | This object is used to create multiple rows in the mgEndpointTable as specified in the SNMP PDU, starting from the row specified by the index of the instance for the number of rows specified in this object. The repetition operation will start from the mgEndpointNumber, mgEndpointLineNumber and mgEndpointChannelMap that is specified in the PDU and will add rows for the number specified in this object. If for a given mgEndpointLineNumber all the endpoints channels are exhausted, it will proceed to the next mgEndpointLineNumber. This will continue until the number of repetitions specified in this object is exhausted or the number of DS1s and endpoints is exhausted, whichever comes first. The agent will need to be able to populate the objects in the mgEndpointTable with the appropriate values as new rows are created. |
| ROW mgEndpointRowStatus | 1.3.6.1.4.1.351.150.10.1.3.1.1.7 | RowStatus | read-create | Controls the creation and deletion of a table entry. An entry may be created using the 'createAndGo' option. When the row is successfully created, the RowStatus would be set to 'active' by the agent thereby creating an endpoint. An endpoint may be deleted by setting the RowStatus to 'destroy'. Other options such as `createAndWait', 'notInService', 'notReady' will not be used. On creation, values for mgEndpointLineNumber and mgEndpointChannelMap have to be supplied. |
| U32 mgEndpointSpeed | 1.3.6.1.4.1.351.150.10.1.3.1.1.4 | Unsigned32 | read-only | Indicates the endpoint's bandwidth, in Kbps. Typically, this will be 64 times the number of channels terminated by the endpoint. |
| INT mgEndpointState | 1.3.6.1.4.1.351.150.10.1.3.1.1.5 | INTEGER | read-only | Indicates the state of the endpoint. 'mgEndpointActive' - the endpoint is in service and operational. 'mgEndpointFailed' - the endpoint is in service but not operational, e.g. because a line that the endpoint belongs to is in a state of service affecting alarm. 'mgEndpointDegraded' - the endpoint is in service but not fully operational, e.g. in cases with endpoints with channels on multiple lines, when one of the lines is in a state of service affecting alarm If MGCP is used as the control protocol, the following transitions will generally trigger an RSIP command: from 'mgEndpointActive'/'mgEndpointDegraded' to 'mgEndpointFailed' or from 'mgEndpointFailed' to 'mgEndpointDegraded'/'mgEndpointActive'. Transitions between 'mgEndpointActive' and 'mgEndpointDegraded' will generally not trigger emission of RSIP. |

| STR mgName | 1.3.6.1.4.1.351.150.10.1.1.1 | SnmpAdminString | read-write | Denotes name of the MG, as it is identified by media gateway controllers. This corresponds to a domain name under which the Media Gateway could also be registered in a DNS. |
| STR mgProtocolName | 1.3.6.1.4.1.351.150.10.1.1.7.1.2 | SnmpAdminString | read-only | A control protocol and its revision supported by the call gateway. For example: 'MGCP 0.1 11/9/99' The protocol can be one of the control protocols like MGCP or it can be a signaling backhaul protocol or it can be resource co-ordination protocol like SRCP. |
| I32 mgProtocolNumber | 1.3.6.1.4.1.351.150.10.1.1.7.1.1 | Integer32 | not-accessible | Serves as index to this table. |
| I32 mgShutdownGraceTime | 1.3.6.1.4.1.351.150.10.1.1.4 | Integer32 | read-write | This object indicates the time in seconds after which an MG will transition from 'gracefulOutOfService' to 'forcefulOutOfService'. A value of -1 indicates that the MG allows for draining, i.e. will automatically transition after the last resource in use has been released. Otherwise, it essentially indicates the amount of time an MGC has to perform any cleanup, e.g. deletion of connections etc. |
| mgSupportedProtocolEntry | 1.3.6.1.4.1.351.150.10.1.1.7.1 | not-accessible | Represents an individual table entry in mgSupportedProtocolTable. | |
| mgSupportedProtocolTable | 1.3.6.1.4.1.351.150.10.1.1.7 | not-accessible | This is a table which identifies the protocols, along with their revisions that the media gateway supports for purposes of communication with an MGC. The table is created by the agent at system startup and cannot changed. |
