Managed objects defined in this MIB module are structured in three kinds of objects: - transaction objects required according to the MIDCOM protocol requirements defined in RFC 3304 and according to the MIDCOM protocol semantics defined in RFC 3989, - configuration objects that can be used for retrieving or setting parameters of the implementation of transaction objects, - optional monitoring objects that provide information about used resource and statistics The transaction objects are organized in two subtrees: - objects modeling MIDCOM policy rules in the midcomRuleTable - objects modeling MIDCOM policy rule groups in the midcomGroupTable Note that typically, configuration objects are not intended to be written by MIDCOM clients. In general, write access to these objects needs to be restricted more strictly than write access to objects in the transaction subtrees. Copyright (C) The Internet Society (2008). This version of this MIB module is part of RFC 5190; see the RFC itself for full legal notices."

This object SHOULD uniquely identify an authenticated MIDCOM client. This object is part of the table index to allow for the use of the SNMPv3 View-based Access Control Model (VACM, RFC 3415)." ::= { midcomRuleEntry 1 } midcomRuleIndex OBJECT-TYPE SYNTAX Unsigned32 (1..4294967295) MAX-ACCESS not-accessible STATUS current DESCRIPTION "The value of this object must be unique in combination with the values of the objects midcomRuleOwner and midcomGroupIndex in this row." ::= { midcomRuleEntry 3 } midcomRuleAdminStatus OBJECT-TYPE SYNTAX INTEGER { reserve(1), enable(2), notSet(3) } MAX-ACCESS read-create STATUS current DESCRIPTION "The value of this object indicates the desired status of the policy rule. See the definition of midcomRuleOperStatus for a description of the values. When a midcomRuleEntry is created without explicitly setting this object, its value will be notSet(3). However, a SET request can only set this object to either reserve(1) or enable(2). Attempts to set this object to notSet(3) will always fail with an 'inconsistentValue' error. Note that this error code is SNMP specific. If the MIB module is used with other protocols than SNMP, errors with similar semantics specific to those protocols should be returned. When the midcomRuleAdminStatus object is set, then the MIDCOM-MIB implementation will try to read the respective relevant objects of the entry and try to achieve the corresponding midcomRuleOperStatus. Setting midcomRuleAdminStatus to value reserve(1) when object midcomRuleOperStatus has a value of reserved(7) does not have any effect on the policy rule. Setting midcomRuleAdminStatus to value enable(2) when object midcomRuleOperStatus has a value of enabled(8) does not have any effect on the policy rule. Depending on whether the midcomRuleAdminStatus is set to reserve(1) or enable(2), several objects must be set in advance. They serve as parameters of the policy rule to be established. When object midcomRuleAdminStatus is set to reserve(1), then the following objects in the same entry are of relevance: - midcomRuleInterface - midcomRuleTransportProtocol - midcomRulePortRange - midcomRuleInternalIpVersion - midcomRuleExternalIpVersion - midcomRuleInternalIpAddr - midcomRuleInternalIpPrefixLength - midcomRuleInternalPort - midcomRuleLifetime MIDCOM-MIB implementation may also consider the value of object midcomRuleMaxIdleTime when establishing a reserve rule. When object midcomRuleAdminStatus is set to enable(2), then the following objects in the same entry are of relevance: - midcomRuleInterface - midcomRuleFlowDirection - midcomRuleMaxIdleTime - midcomRuleTransportProtocol - midcomRulePortRange - midcomRuleInternalIpVersion - midcomRuleExternalIpVersion - midcomRuleInternalIpAddr - midcomRuleInternalIpPrefixLength - midcomRuleInternalPort - midcomRuleExternalIpAddr - midcomRuleExternalIpPrefixLength - midcomRuleExternalPort - midcomRuleLifetime When retrieved, the object returns the last set value. If no value has been set, it returns the default value notSet(3)." DEFVAL { notSet } ::= { midcomRuleEntry 4 } midcomRuleOperStatus OBJECT-TYPE SYNTAX INTEGER { newEntry(1), setting(2), checkingRequest(3), incorrectRequest(4), processingRequest(5), requestRejected(6), reserved(7), enabled(8), timedOut(9), terminatedOnRequest(10), terminated(11), genericError(12) } MAX-ACCESS read-only STATUS current DESCRIPTION "The actual status of the policy rule. The midcomRuleOperStatus object may have the following values: - newEntry(1) indicates that the entry in the midcomRuleTable was created, but not modified yet. Such an entry needs to be filled with values specifying a request first. - setting(2) indicates that the entry has been already modified after generating it, but no request was made yet. - checkingRequest(3) indicates that midcomRuleAdminStatus has recently been set and that the MIDCOM-MIB implementation is currently checking the parameters of the request. This is a transient state. The value of this object will change to either incorrectRequest(4) or processingRequest(5) without any external interaction. A MIDCOM-MIB implementation MAY return this value while checking request parameters. - incorrectRequest(4) indicates that checking a request resulted in detecting an incorrect value in one of the objects containing request parameters. The failure reason is indicated by the value of midcomRuleError. - processingRequest(5) indicates that midcomRuleAdminStatus has recently been set and that the MIDCOM-MIB implementation is currently processing the request and trying to configure the middlebox accordingly. This is a transient state. The value of this object will change to either requestRejected(6), reserved(7), or enabled(8) without any external interaction. A MIDCOM-MIB implementation MAY return this value while processing a request. - requestRejected(6) indicates that a request to establish a policy rule specified by the entry was rejected. The reason for rejection is indicated by the value of midcomRuleError. - reserved(7) indicates that the entry describes an established policy reserve rule. These values of MidcomRuleEntry are meaningful for a reserved policy rule: - midcomRuleMaxIdleTime - midcomRuleInterface - midcomRuleTransportProtocol - midcomRulePortRange - midcomRuleInternalIpVersion - midcomRuleExternalIpVersion - midcomRuleInternalIpAddr - midcomRuleInternalIpPrefixLength - midcomRuleInternalPort - midcomRuleOutsideIpAddr - midcomRuleOutsidePort - midcomRuleLifetime - enabled(8) indicates that the entry describes an established policy enable rule. These values of MidcomRuleEntry are meaningful for an enabled policy rule: - midcomRuleFlowDirection - midcomRuleInterface - midcomRuleMaxIdleTime - midcomRuleTransportProtocol - midcomRulePortRange - midcomRuleInternalIpVersion - midcomRuleExternalIpVersion - midcomRuleInternalIpAddr - midcomRuleInternalIpPrefixLength - midcomRuleInternalPort - midcomRuleExternalIpAddr - midcomRuleExternalIpPrefixLength - midcomRuleExternalPort - midcomRuleInsideIpAddr - midcomRuleInsidePort - midcomRuleOutsideIpAddr - midcomRuleOutsidePort - midcomRuleLifetime - timedOut(9) indicates that the lifetime of a previously established policy rule has expired and that the policy rule is terminated for this reason. - terminatedOnRequest(10) indicates that a previously established policy rule was terminated by an SNMP manager setting the midcomRuleLifetime to 0 or setting midcomGroupLifetime to 0. - terminated(11) indicates that a previously established policy rule was terminated by the MIDCOM-MIB implementation for a reason other than lifetime expiration or an explicit request from a MIDCOM client. - genericError(12) indicates that the policy rule specified by the entry is not established due to an error condition not listed above. The states timedOut(9), terminatedOnRequest(10), and terminated(11) are referred to as termination states. The states incorrectRequest(4), requestRejected(6), and genericError(12) are referred to as error states. The checkingRequest(3) and processingRequest(5) states are transient states, which will lead to either one of the error states or the reserved(7) state or the enabled(8) state. MIDCOM-MIB implementations MAY return these values when checking or processing requests." DEFVAL { newEntry } ::= { midcomRuleEntry 5 } midcomRuleStorageType OBJECT-TYPE SYNTAX StorageType MAX-ACCESS read-create STATUS current DESCRIPTION "When retrieved, this object returns the storage type of the policy rule. Writing to this object can change the storage type of the particular row from volatile(2) to nonVolatile(3) or vice versa. Attempts to set this object to permanent will always fail with an 'inconsistentValue' error. Note that this error code is SNMP specific. If the MIB module is used with other protocols than SNMP, errors with similar semantics specific to those protocols should be returned. If midcomRuleStorageType has the value permanent(4), then all objects in this row whose MAX-ACCESS value is read-create must be read-only." DEFVAL { volatile } ::= { midcomRuleEntry 6 } midcomRuleStorageTime OBJECT-TYPE SYNTAX Unsigned32 UNITS "seconds" MAX-ACCESS read-create STATUS current DESCRIPTION "The value of this object specifies how long this row can exist in the midcomRuleTable after the midcomRuleOperStatus switched to a termination state or to an error state. This object returns the remaining time that the row may exist before it is aged out. After expiration or termination of the context, the value of this object ticks backwards. The entry in the midcomRuleTable is destroyed when the value reaches 0. The value of this object may be set in order to increase or reduce the remaining time that the row may exist. Setting the value to 0 will destroy this entry as soon as the midcomRuleOperStatus switched to a termination state or to an error state. Note that there is no guarantee that the row is stored as long as this object indicates. At any time, the MIDCOM- MIB implementation may decide to remove a row describing a terminated policy rule before the storage time of the corresponding row in the midcomRuleTable reaches the value of 0. In this case, the information stored in this row is not available anymore. If object midcomRuleStorageType indicates that the policy rule has the storage type permanent(4), then this object has a constant value of 4294967295." DEFVAL { 0 } ::= { midcomRuleEntry 7 } midcomRuleError OBJECT-TYPE SYNTAX SnmpAdminString MAX-ACCESS read-only STATUS current DESCRIPTION "This object contains a descriptive error message if the transition into the operational status reserved(7) or enabled(8) failed. Implementations must reset the error message to a zero-length string when a new attempt to change the policy rule status to reserved(7) or enabled(8) is started. RECOMMENDED values to be returned in particular cases include - 'lack of IP addresses' - 'lack of port numbers' - 'lack of resources' - 'specified NAT interface does not exist' - 'specified NAT interface does not support NAT' - 'conflict with already existing policy rule' - 'no internal IP wildcarding allowed' - 'no external IP wildcarding allowed' The semantics of these error messages and the corresponding behavior of the MIDCOM-MIB implementation are specified in sections 2.3.9 and 2.3.10 of RFC 3989." REFERENCE "RFC 3989, sections 2.3.9 and 2.3.10" DEFVAL { ''H } ::= { midcomRuleEntry 8 } midcomRuleInterface OBJECT-TYPE SYNTAX InterfaceIndexOrZero MAX-ACCESS read-create STATUS current DESCRIPTION "This object indicates the IP interface for which enforcement of a policy rule is requested or performed, respectively. The interface is identified by its index in the ifTable (see IF-MIB in RFC 2863). If the object has a value of 0, then no particular interface is indicated. This object is used as input to a request for establishing a policy rule as well as for indicating the properties of an established policy rule. If object midcomRuleOperStatus of the same entry has the value newEntry(1) or setting(2), then this object can be written by a manager in order to request its preference concerning the interface at which it requests NAT service. The default value of 0 indicates that the manager does not have a preferred interface or does not have sufficient topology information for specifying one. Writing to this object in any state other than newEntry(1) or setting(2) will always fail with an 'inconsistentValue' error. Note that this error code is SNMP specific. If the MIB module is used with other protocols than SNMP, errors with similar semantics specific to those protocols should be returned. If object midcomRuleOperStatus of the same entry has the value reserved(7) or enabled(8), then this object indicates the interface at which NAT service for this rule is performed. If NAT service is not required for enforcing the policy rule, then the value of this object is 0. Also, if the MIDCOM-MIB implementation cannot indicate an interface, because it does not have this information or because NAT service is not offered at a particular single interface, then the value of the object is 0. Note that the index of a particular interface in the ifTable may change after a re-initialization of the middlebox, for example, after adding another interface to it. In such a case, the value of this object may change, but the interface referred to by the MIDCOM-MIB MUST still be the same. If, after a re-initialization of the middlebox, the interface referred to before re-initialization cannot be uniquely mapped anymore to a particular entry in the ifTable, then the value of object midcomRuleOperStatus of the same entry MUST be changed to terminated(11). If object midcomRuleOperStatus of the same entry has a value other than newEntry(1), setting(2), reserved(7), or enabled(8), then the value of this object is irrelevant." DEFVAL { 0 } ::= { midcomRuleEntry 9 } midcomRuleFlowDirection OBJECT-TYPE SYNTAX INTEGER { inbound(1), outbound(2), biDirectional(3) } MAX-ACCESS read-create STATUS current DESCRIPTION "This parameter specifies the direction of enabled communication, either inbound(1), outbound(2), or biDirectional(3). The semantics of this object depends on the protocol the rule relates to. If the rule is independent of the transport protocol (midcomRuleTransportProtocol has a value of 0) or if the transport protocol is UDP, then the value of midcomRuleFlowDirection indicates the direction of packets traversing the middlebox. In this case, value inbound(1) indicates that packets are traversing from outside to inside, value outbound(2) indicates that packets are traversing from inside to outside. For both values, inbound(1) and outbound(2) packets can traverse the middlebox only unidirectional. A bidirectional flow is indicated by value biDirectional(3). If the transport protocol is TCP, the packet flow is always bidirectional, but the value of midcomRuleFlowDirection indicates that: - inbound(1): bidirectional TCP packet flow. First packet, with TCP SYN flag set, must arrive at an outside interface of the middlebox. - outbound(2): bidirectional TCP packet flow. First packet, with TCP SYN flag set, must arrive at an inside interface of the middlebox. - biDirectional(3): bidirectional TCP packet flow. First packet, with TCP SYN flag set, may arrive at an inside or an outside interface of the middlebox. This object is used as input to a request for establishing a policy enable rule as well as for indicating the properties of an established policy rule. If object midcomRuleOperStatus of the same entry has a value of either newEntry(1), setting(2), or reserved(7), then this object can be written by a manager in order to specify a requested direction to be enabled by a policy rule. Writing to this object in any state other than newEntry(1), setting(2), or reserved(7) will always fail with an 'inconsistentValue' error. Note that this error code is SNMP specific. If the MIB module is used with other protocols than SNMP, errors with similar semantics specific to those protocols should be returned. If object midcomRuleOperStatus of the same entry has the value enabled(8), then this object indicates the enabled flow direction. If object midcomRuleOperStatus of the same entry has a value other than newEntry(1), setting(2), reserved(7), or enabled(8), then the value of this object is irrelevant." DEFVAL { outbound } ::= { midcomRuleEntry 10 } midcomRuleMaxIdleTime OBJECT-TYPE SYNTAX Unsigned32 UNITS "seconds" MAX-ACCESS read-create STATUS current DESCRIPTION "Maximum idle time of the policy rule in seconds. If no packet to which the policy rule applies passes the middlebox for the specified midcomRuleMaxIdleTime, then the policy rule enters the termination state timedOut(9). A value of 0 indicates that the policy does not require an individual idle time and that instead, a default idle time chosen by the middlebox is used. A value of 4294967295 ( = 2^32 - 1 ) indicates that the policy does not time out if it is idle. This object is used as input to a request for establishing a policy enable rule as well as for indicating the properties of an established policy rule. If object midcomRuleOperStatus of the same entry has a value of either newEntry(1), setting(2), or reserved(7), then this object can be written by a manager in order to specify a maximum idle time for the policy rule to be requested. Writing to this object in any state others than newEntry(1), setting(2), or reserved(7) will always fail with an 'inconsistentValue' error. Note that this error code is SNMP specific. If the MIB module is used with other protocols than SNMP, errors with similar semantics specific to those protocols should be returned. If object midcomRuleOperStatus of the same entry has the value enabled(8), then this object indicates the maximum idle time of the policy rule. Note that even if a maximum idle time greater than zero was requested, the middlebox may not be able to support maximum idle times and set the value of this object to zero when entering state enabled(8). If object midcomRuleOperStatus of the same entry has a value other than newEntry(1), setting(2), reserved(7), or enabled(8), then the value of this object is irrelevant." DEFVAL { 0 } ::= { midcomRuleEntry 11 } midcomRuleTransportProtocol OBJECT-TYPE SYNTAX Unsigned32 (0..255) MAX-ACCESS read-create STATUS current DESCRIPTION "The transport protocol.

If the MIB module is used with other protocols than SNMP, errors with similar semantics specific to those protocols should be returned. If object midcomRuleOperStatus of the same entry has the value reserved(7) or enabled(8), then this object indicates which transport protocol is enforced by this policy rule.

If object midcomRuleOperStatus of the same entry has the value newEntry(1) or setting(2), then this object can be written by a manager in order to specify the requested size of the port range. With single(1) just a single port number is requested, with pair(2) a consecutive pair of port numbers is requested with the lower number being even. Requesting a consecutive pair of port numbers may be used by RTP [RFC3550] and may even be required to support older RTP applications. Writing to this object in any state other than newEntry(1), setting(2) or reserved(7) will always fail with an 'inconsistentValue' error. Note that this error code is SNMP specific.
