MPC-MIB: View SNMP OID List / Download MIB

This module defines a portion of the management information base (MIB) for managing Multiprotocol Over ATM clients and servers which was revised based on MPOA Errata contained in MPOA v1.1. The difference between af-mpoa-0092.000 and this version is the mpcMpsMacAddressTable has been obsoleted. The mpcMpsMultipleMacAddressTable has been added. The mpcMpsMultipleMacAddressTable replaces the mpcMpsMacAddressTable.

This object contains an appropriate value to be used for mpcIndex when creating entries in the mpcConfigTable. The value 0 indicates that no new rows can be created. Otherwise, it is recommended that values are assigned contiguously, starting from 1. MPC creation by a Manager: To obtain the mpcIndex value for a new entry, the manager issues a management protocol retrieval operation to obtain the current value of this object. If the value retrieved is 0 (zero), the manager cannot create a row. After each retrieval of a non-zero value, the manager should issue a management protocol SET operation using the value just retrieved. If the SET is successful, the agent should update the value to the next unassigned index, or zero if appropriate. NOTE: the manager may also issue a set on this object with a value of its own choosing. If the set is successful, the manager may use this value for the mpcIndex. In this case, the agent would update the value to the next unassigned index, or zero if appropriate. The definition of `next unassigned index' is any mpcNextIndex value that has not yet been set by a manager, or reserved by the agent (see next paragraph), since this agent was last re-initialized. MPC creation by an Agent: When a row in the mpcConfigTable is created by an agent, the agent should reserve the value of the index by updating the value of this object to the next unassigned index or zero if appropriate. Thus, a manager will not be able to set an index reserved by an agent. In the situation of an agent re-initialization, all currently used mpcIndexes must be preserved. In other words, the Agent should store in non-volatile memory all of the currently used mpcIndexes (along with all necessary configuration information from the mpcConfigTable). When the agent is re-initialized, the mpcNextIndex value is any valid Integer32 value which is not being used as an mpcIndex, except 0 which maintains its original definition of indicating that a row cannot be created.

The MPOA Client Configuration Table. This table contains configuration information for all MPOA Clients which this agent manages.

MPOA Client Configuration Entry. Each entry contains configuration information for one MPOA Client. The configuration information, including the mpcIndex, must be restored after a re-initialization of an MPC or a re-initialization of the SNMP agent.

A value which uniquely identifies this conceptual row in the mpcConfigTable. The `mpcNextIndex' object needs to be used to determine the value of this object. A row cannot be added, unless the mpcCtrlAtmAddress is unique. In the event of either an MPC re-initialization or an agent re-initialization, the value of this mpcIndex must remain the same. In other words, the row needs to be saved and restored in the event of an MPC or SNMP Agent re-initialization.

This object allows creation and deletion of MPOA Clients. Within each conceptual mpcConfigTable row, writable objects may be modified, regardless of the value of mpcRowStatus. It is not necessary to set a row's status to `notInService' first. A row cannot be created, unless the mpcAtmCtrlAddress in this table is unique. When an MPOA Client is created via this object, it will initially have `mpcActualState' = `initialState'

Indicates whether this MPC should auto-configure the next time it is (re-)initialized. During the (re-)initialization of this MPC, if the mode is automatic(1), the LECS is contacted and requests are made for all MPC-p* parameters. Otherwise, if the mode is manual(2), the values of the configuration parameters are obtained from the mpcConfigTableand the mpcProtocolTable. In other words, when the MPC is first initialized, it can use the default or configured values from the mpcConfigTable and mpcProtocolTable. If the mode is manual (2), no further action is required. If the mode is automatic (1), then the LECS should be contacted and all available MPC-p1 to MPC-p6 parameters would be retrieved. These parameters would then overwrite the existing MPC-p1 to MPC-p6 parameters. The actual values are reflected in the mpcActualTable. Enumeration: 'manual': 2, 'automatic': 1.

The MPC's Control ATM Address. There exists one Control ATM Address per MPC, therefore, the value of this entry is unique within the table. The control ATM Address is the address which is used by the MPC in its requests to the MPS. The value of this object should not change, once created.

This represents the MPC-p1 Short-cut setup frame count parameter. The MPC-p1 value is frames measured over mpcSCFrameTime seconds. Flow detection is protocol independent. i.e. all network layers mpcProtocolEntries for this MPC share the flow rate specification. A value of 1 causes all flows to initiate resolution/shortcut process.

MPC-p2 Short-cut setup frame time, in seconds.

MPC-p4 is the initial value for the retry time out period used for timing out MPOA Resolution Requests in seconds. Retry time consists of this initial time-out (MPC-p4) and a retry multiplier (MPC-c1). If a response is not received, then another request is sent with a timeout of `retry time' * MPC-c1 seconds, or until mpcRetryTimeMaximum.

MPC-p5 cumulative max value for Retry Time (MPC-p4). Retries are attempted at intervals determined by the algorithm described in the definition of mpcIntialRetryTime.

MPC-p6 Hold Down Time Minimum time to wait before reinitiating a failed resolution attempt. Default is mpcRetryTimeMaximum * 4.

MPOA Client Actual Table. A read-only table which contains state information and reflects the actual values which these MPOA Clients are using. The actual values may differ from the configured values. For example, the mpcConfigMode takes affect only during (re-)initialization of the MPC. The MPC-p1 to MPC-p6 parameters may differ from the configured values because, if the MPC was (re-)initialized and the mpcConfigMode was set to automatic (1) then some, perhaps all, of the MPC-p1 to MPC-p6 parameters were retrieved from the LECS and the values from the LECS may differ from the configured/default values of the mpcConfigTable. NOTE: after re-initialization a set to an object in the mpcConfigTable which changes the value of the object will be reflect in this Table, except for a set to the mpcConfigMode which takes effect only during re-initialization.

An entry in the MPC Actual Table. An entry represents a specific MPOA Client's state information and the actual values which are being used by the MPOA Client. For example, the corresponding mpcConfigEntry contains default and/or configured parameters, if mpcConfigMode was set to manual, then these are the objects values' which are reflected for the mpcActualEntry. However, if the mpcConfigMode is automatic, then the mpcActualEntry will be all the corresponding mpcConfigEntry's object, excluding any objects which were retrieved from the LECS. In other words, the objects retrieved from the LECS during the (re-)initialization of the MPC overwrite any of the default and/or configured values. NOTE: any subsequent `set' to the configured values, e.g. an SNMP set operation, which is successful could result in a change to an mpcConfigTable value, and will be reflected in this table as well.

This object indicates the actual state of the MPOA Client. Enumeration: 'down': 4, 'unknown': 1, 'up': 3, 'initialState': 2.

The value of sysUpTime on the most recent occasion at which any one or more of this MPC's counters experienced a discontinuity. The relevant counters are the specific instances associated with this MPC. If discontinuities have not occurred since the last re-initialization of the local management subsystem, then this object contains a zero value.

Indicates whether this MPC auto-configured when it was last (re-)initialized. Enumeration: 'manual': 2, 'automatic': 1.

MPC-p1 Short-cut setup frame count. In frames measured over mpcShortcutFrameTime seconds. Flow detection is protocol independent. i.e. all network layers mpcProtocolEntry share the flow rate specification. A value of 1 implies that resolutions for short-cuts are attempted for all flows.

Actual MPC-p2 Short-cut setup frame time, in seconds.

Actual MPC-p4 is initial value for the retry time out.

MPC-p5 cumulative maximum value for Retry Time (MPC-p4). Retries are attempted at intervals determined by the algorithm described in the definition of mpcActualInitialRetryTime.

MPC-p6 Hold Down Time Minimum time to wait before reinitiating a failed resolution attempt. The default value is mpcRetryTimeMaximum * 4.
