CISCO-WAN-MG-MIB file content
The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.
Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

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'.

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.

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.

The possible value for a set operation on this object are: 'mgcUnassociate': Transition from any state to 'mgcUnassociated'. If registered, MG will initiate unregistration. '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.

'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."

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."

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." ::= { mgcEntry 8 } -- ********************************************************************* -- Media Gateway Controller Protocol Table -- ********************************************************************* mgcProtocolTable OBJECT-TYPE SYNTAX SEQUENCE OF MgcProtocolEntry MAX-ACCESS not-accessible STATUS deprecated DESCRIPTION "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." ::= { mediaGatewayController 2 } mgcProtocolEntry OBJECT-TYPE SYNTAX MgcProtocolEntry MAX-ACCESS not-accessible STATUS deprecated DESCRIPTION "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."

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.

'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'.
