The management information definitions for the View-based Access Control Model for SNMP. Copyright (C) The Internet Society (2002). This version of this MIB module is part of RFC 3415; see the RFC itself for full legal notices. not-accessible current 1.3.6.1.6.3.16.1.1.1 Information about a particular context. not-accessible current 1.3.6.1.6.3.16.1.2.1 An entry in this table maps the combination of a securityModel and securityName into a groupName. not-accessible current 1.3.6.1.6.3.16.1.4.1 An access right configured in the Local Configuration Datastore (LCD) authorizing access to an SNMP context. Entries in this table can use an instance value for object vacmGroupName even if no entry in table vacmAccessSecurityToGroupTable has a corresponding value for object vacmGroupName. read-write current 1.3.6.1.6.3.16.1.5.1 An advisory lock used to allow cooperating SNMP Command Generator applications to coordinate their use of the Set operation in creating or modifying views. When creating a new view or altering an existing view, it is important to understand the potential interactions with other uses of the view. The vacmViewSpinLock should be retrieved. The name of the view to be created should be determined to be unique by the SNMP Command Generator application by consulting the vacmViewTreeFamilyTable. Finally, the named view may be created (Set), including the advisory lock. If another SNMP Command Generator application has altered the views in the meantime, then the spin lock's value will have changed, and so this creation will fail because it will specify the wrong value for the spin lock. Since this is an advisory lock, the use of this lock is not enforced. read-write current 1.3.6.1.6.3.16.1.5.1 An advisory lock used to allow cooperating SNMP Command Generator applications to coordinate their use of the Set operation in creating or modifying views.

Implementations must not restrict the number of families of view subtrees for a given MIB view, except as dictated by resource constraints on the overall number of entries in the vacmViewTreeFamilyTable. If no conceptual rows exist in this table for a given MIB view (viewName), that view may be thought of as consisting of the empty set of view subtrees. read-only current 1.3.6.1.6.3.16.1.1.1.1 A human readable name identifying a particular context at a particular SNMP entity. The empty contextName (zero length) represents the default context. "255t" read-write current 1.3.6.1.6.3.16.1.2.1.3 The name of the group to which this entry (e.g., the combination of securityModel and securityName) belongs. This groupName is used as index into the vacmAccessTable to select an access control policy. However, a value in this table does not imply that an instance with the value exists in table vacmAccesTable. "255t" read-write current 1.3.6.1.6.3.16.1.2.1.4 The storage type for this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row. 1 -- eh? 2 -- e.g., in RAM 3 -- e.g., in NVRAM 4 -- e.g., partially in ROM 5 -- e.g., completely in ROM read-write current 1.3.6.1.6.3.16.1.2.1.5 The status of this conceptual row. Until instances of all corresponding columns are appropriately configured, the value of the corresponding instance of the vacmSecurityToGroupStatus column is 'notReady'. In particular, a newly created row cannot be made active until a value has been set for vacmGroupName. The RowStatus TC [RFC2579] requires that this DESCRIPTION clause states under which circumstances other objects in this row can be modified: The value of this object has no effect on whether other objects in this conceptual row can be modified. 1 2 -- the following value is a state: -- this value may be read, but not written 3 -- the following three values are -- actions: these values may be written, -- but are never read 4 5 6 read-write current 1.3.6.1.6.3.16.1.4.1.4 If the value of this object is exact(1), then all rows where the contextName exactly matches vacmAccessContextPrefix are selected. If the value of this object is prefix(2), then all rows where the contextName whose starting octets exactly match vacmAccessContextPrefix are selected. This allows for a simple form of wildcarding. 1 -- exact match of prefix and contextName 2 -- Only match to the prefix read-write current 1.3.6.1.6.3.16.1.4.1.5 The value of an instance of this object identifies the MIB view of the SNMP context to which this conceptual row authorizes read access. The identified MIB view is that one for which the vacmViewTreeFamilyViewName has the same value as the instance of this object; if the value is the empty string or if there is no active MIB view having this value of vacmViewTreeFamilyViewName, then no access is granted. "255t" read-write current 1.3.6.1.6.3.16.1.4.1.6 The value of an instance of this object identifies the MIB view of the SNMP context to which this conceptual row authorizes write access. The identified MIB view is that one for which the vacmViewTreeFamilyViewName has the same value as the instance of this object; if the value is the empty string or if there is no active MIB view having this value of vacmViewTreeFamilyViewName, then no access is granted. "255t" read-write current 1.3.6.1.6.3.16.1.4.1.7 The value of an instance of this object identifies the MIB view of the SNMP context to which this conceptual row authorizes access for notifications. The identified MIB view is that one for which the vacmViewTreeFamilyViewName has the same value as the instance of this object; if the value is the empty string or if there is no active MIB view having this value of vacmViewTreeFamilyViewName, then no access is granted. "255t" read-write current 1.3.6.1.6.3.16.1.4.1.8 The storage type for this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row. 1 -- eh? 2 -- e.g., in RAM 3 -- e.g., in NVRAM 4 -- e.g., partially in ROM 5 -- e.g., completely in ROM read-write current 1.3.6.1.6.3.16.1.4.1.9 The status of this conceptual row. The RowStatus TC [RFC2579] requires that this DESCRIPTION clause states under which circumstances other objects in this row can be modified: The value of this object has no effect on whether other objects in this conceptual row can be modified. 1 2 -- the following value is a state: -- this value may be read, but not written 3 -- the following three values are -- actions: these values may be written, -- but are never read 4 5 6 read-write current 1.3.6.1.6.3.16.1.5.2.1.3 The bit mask which, in combination with the corresponding instance of vacmViewTreeFamilySubtree, defines a family of view subtrees. Each bit of this bit mask corresponds to a sub-identifier of vacmViewTreeFamilySubtree, with the most significant bit of the i-th octet of this octet string value (extended if necessary, see below) corresponding to the (8*i - 7)-th sub-identifier, and the least significant bit of the i-th octet of this octet string corresponding to the (8*i)-th sub-identifier, where i is in the range 1 through 16. Each bit of this bit mask specifies whether or not the corresponding sub-identifiers must match when determining if an OBJECT IDENTIFIER is in this family of view subtrees; a '1' indicates that an exact match must occur; a '0' indicates 'wild card', i.e., any sub-identifier value matches. Thus, the OBJECT IDENTIFIER X of an object instance is contained in a family of view subtrees if, for each sub-identifier of the value of vacmViewTreeFamilySubtree, either: the i-th bit of vacmViewTreeFamilyMask is 0, or the i-th sub-identifier of X is equal to the i-th sub-identifier of the value of vacmViewTreeFamilySubtree. If the value of this bit mask is M bits long and there are more than M sub-identifiers in the corresponding instance of vacmViewTreeFamilySubtree, then the bit mask is extended with 1's to be the required length. Note that when the value of this object is the zero-length string, this extension rule results in a mask of all-1's being used (i.e., no 'wild card'), and the family of view subtrees is the one view subtree uniquely identified by the corresponding instance of vacmViewTreeFamilySubtree. Note that masks of length greater than zero length do not need to be supported. In this case this object is made read-only. read-write current 1.3.6.1.6.3.16.1.5.2.1.4 Indicates whether the corresponding instances of vacmViewTreeFamilySubtree and vacmViewTreeFamilyMask define a family of view subtrees which is included in or excluded from the MIB view. 1 2 read-write current 1.3.6.1.6.3.16.1.5.2.1.5 The storage type for this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row. 1 -- eh? 2 -- e.g., in RAM 3 -- e.g., in NVRAM 4 -- e.g., partially in ROM 5 -- e.g., completely in ROM read-write current 1.3.6.1.6.3.16.1.5.2.1.6 The status of this conceptual row. The RowStatus TC [RFC2579] requires that this DESCRIPTION clause states under which circumstances other objects in this row can be modified: The value of this object has no effect on whether other objects in this conceptual row can be modified. 1 2 -- the following value is a state: -- this value may be read, but not written 3 -- the following three values are -- actions: these values may be written, -- but are never read 4 5 6
