DESCRIPTION "The table of locally available contexts.
|
|
|
|
This table provides information to SNMP Command
|
|
Generator applications so that they can properly
|
|
configure the vacmAccessTable to control access to
|
|
all contexts at the SNMP entity.
|
|
|
|
This table may change dynamically if the SNMP entity
|
|
allows that contexts are added/deleted dynamically
|
|
(for instance when its configuration changes). Such
|
|
changes would happen only if the management
|
|
instrumentation at that SNMP entity recognizes more
|
|
(or fewer) contexts.
|
|
|
|
The presence of entries in this table and of entries
|
|
in the vacmAccessTable are independent. That is, a
|
|
context identified by an entry in this table is not
|
|
necessarily referenced by any entries in the
|
|
vacmAccessTable; and the context(s) referenced by an
|
|
entry in the vacmAccessTable does not necessarily
|
|
currently exist and thus need not be identified by an
|
|
entry in this table.
|
|
|
|
This table must be made accessible via the default
|
|
context so that Command Responder applications have
|
|
a standard way of retrieving the information.
|
|
|
|
This table is read-only. It cannot be configured via
|
|
SNMP.

DESCRIPTION "The table of access rights for groups.
|
|
|
|
Each entry is indexed by a groupName, a contextPrefix,
|
|
a securityModel and a securityLevel. To determine
|
|
whether access is allowed, one entry from this table
|
|
needs to be selected and the proper viewName from that
|
|
entry must be used for access control checking.
|
|
|
|
To select the proper entry, follow these steps:
|
|
|
|
1) the set of possible matches is formed by the
|
|
intersection of the following sets of entries:
|
|
the set of entries with identical vacmGroupName
|
|
the union of these two sets:
|
|
- the set with identical vacmAccessContextPrefix
|
|
- the set of entries with vacmAccessContextMatch
|
|
value of 'prefix' and matching
|
|
vacmAccessContextPrefix
|
|
intersected with the union of these two sets:
|
|
- the set of entries with identical
|
|
vacmSecurityModel
|
|
- the set of entries with vacmSecurityModel
|
|
value of 'any'
|
|
intersected with the set of entries with
|
|
vacmAccessSecurityLevel value less than or equal
|
|
to the requested securityLevel
|
|
|
|
2) if this set has only one member, we're done
|
|
otherwise, it comes down to deciding how to weight
|
|
the preferences between ContextPrefixes,
|
|
SecurityModels, and SecurityLevels as follows:
|
|
a) if the subset of entries with securityModel
|
|
matching the securityModel in the message is
|
|
not empty, then discard the rest.
|
|
b) if the subset of entries with
|
|
vacmAccessContextPrefix matching the contextName
|
|
in the message is not empty,
|
|
then discard the rest
|
|
c) discard all entries with ContextPrefixes shorter
|
|
than the longest one remaining in the set
|
|
d) select the entry with the highest securityLevel
|
|
|
|
Please note that for securityLevel noAuthNoPriv, all
|
|
groups are really equivalent since the assumption that
|
|
the securityName has been authenticated does not hold.

When creating a new view or altering an existing

|
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.

DESCRIPTION "Locally held information about families of subtrees
|
|
within MIB views.
|
|
|
|
Each MIB view is defined by two sets of view subtrees:
|
|
- the included view subtrees, and
|
|
- the excluded view subtrees.
|
|
Every such view subtree, both the included and the
|
|
excluded ones, is defined in this table.
|
|
|
|
To determine if a particular object instance is in
|
|
a particular MIB view, compare the object instance's
|
|
OBJECT IDENTIFIER with each of the MIB view's active
|
|
entries in this table. If none match, then the
|
|
object instance is not in the MIB view. If one or
|
|
more match, then the object instance is included in,
|
|
or excluded from, the MIB view according to the
|
|
value of vacmViewTreeFamilyType in the entry whose
|
|
value of vacmViewTreeFamilySubtree has the most
|
|
sub-identifiers. If multiple entries match and have
|
|
the same number of sub-identifiers (when wildcarding
|
|
is specified with the value of vacmViewTreeFamilyMask),
|
|
then the lexicographically greatest instance of
|
|
vacmViewTreeFamilyType determines the inclusion or
|
|
exclusion.
|
|
|
|
An object instance's OBJECT IDENTIFIER X matches an
|
|
active entry in this table when the number of
|
|
sub-identifiers in X is at least as many as in the
|
|
value of vacmViewTreeFamilySubtree for the entry,
|
|
and each sub-identifier in the value of
|
|
vacmViewTreeFamilySubtree matches its corresponding
|
|
sub-identifier in X. Two sub-identifiers match
|
|
either if the corresponding bit of the value of
|
|
vacmViewTreeFamilyMask for the entry is zero (the
|
|
'wild card' value), or if they are equal.
|
|
|
|
A 'family' of subtrees is the set of subtrees defined
|
|
by a particular combination of values of
|
|
vacmViewTreeFamilySubtree and vacmViewTreeFamilyMask.
|
|
In the case where no 'wild card' is defined in the
|
|
vacmViewTreeFamilyMask, the family of subtrees reduces
|
|
to a single subtree.
|
|
|
|
When creating or changing MIB views, an SNMP Command
|
|
Generator application should utilize the
|
|
vacmViewSpinLock to try to avoid collisions. See
|
|
DESCRIPTION clause of vacmViewSpinLock.
|
|
|
|
When creating MIB views, it is strongly advised that
|
|

When deleting MIB views, it is strongly advised that

first the 'included' vacmViewTreeFamilyEntries are

deleted and then the 'excluded' entries.

If a create for an entry for instance-level access

support instance-level granularity, then an

DESCRIPTION "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.
