Abstract
This memo defines Management Information Bases (MIBs) for performing ping, traceroute, and lookup operations at a host. When managing a network, it is useful to be able to initiate and retrieve the results of ping or traceroute operations when they are performed at a remote host. A lookup capability is defined in order to enable resolution of either an IP address to an DNS name or a DNS name to an IP address at a remote host.
Currently, there are several enterprise-specific MIBs for performing remote ping or traceroute operations. The purpose of this memo is to define a standards-based solution to enable interoperability.
Contents
Introduction
This document defines standards-based MIB modules for performing specific remote operations. The remote operations defined by this document consist of the ping, traceroute, and lookup functions.
Ping and traceroute are two very useful functions for managing networks. Ping is typically used to determine whether a path exists between two hosts, whereas traceroute shows an actual path.
Both ping and traceroute yield round-trip times measured in milliseconds. These times can be used as a rough approximation for network transit time.
The lookup functions considered in this document are the equivalents of name to address conversion functions such as gethostbyname()/gethostbyaddr() and getaddrinfo()/getnameinfo().
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 RFC2119.
Ping
Ping is usually implemented using the Internet Control Message Protocol (ICMP) "ECHO" facility. It is also possible to implement a ping capability using alternate methods, including the following:
o Using the UDP echo port (7), if supported.
This is defined by RFC 862 RFC862.
o Timing a Simple Network Management Protocol (SNMP) query.
o Timing a TCP connect attempt.
In general, almost any request/response flow can be used to generate a round-trip time. Often, many of the non-ICMP ECHO facility methods stand a better chance of yielding a good response (not timing out, for example) since some routers don't honor Echo Requests (timeout situation) or are handled at lower priority, thus possibly giving false indications of round trip times.
Note that almost any of the various methods used for generating a round-trip time can be considered a form of system attack when used excessively. Sending a system request too often can negatively effect its performance. Attempting to connect to what is supposed to be an unused port can be very unpredictable. There are tools that attempt to connect to a range of TCP ports to test that any receiving server can handle erroneous connection attempts.
It is also important to a management application using a remote ping capability to know which method is being used. Different methods will yield different response times, since the protocol and resulting processing will be different. It is RECOMMENDED that the ping capability defined within this memo be implemented using the ICMP Echo Facility.
Traceroute
Traceroute is usually implemented by transmitting a series of probe packets with increasing time-to-live values. A probe packet is a UDP datagram encapsulated into an IP packet. Each hop in a path to the target (destination) host rejects the probe packet (probe's TTL too small) until its time-to-live value becomes large enough for the probe to be forwarded. Each hop in a traceroute path returns an ICMP message that is used to discover the hop and to calculate a round trip time. Some systems use ICMP probes (ICMP Echo request packets) instead of UDP ones to implement traceroute. In both cases traceroute relies on the probes being rejected via an ICMP message to discover the hops taken along a path to the final destination. Both probe types, UDP and ICMP, are encapsulated into an IP packet and thus have a TTL field that can be used to cause a path rejection.
Implementations of the remote traceroute capability as defined within this memo SHOULD be done using UDP packets to a (hopefully) unused port. ICMP probes (ICMP Echo Request packets) SHOULD NOT be used. Many PC implementations of traceroute use the ICMP probe method, which they should not, since this implementation method has been known to have a high probability of failure. Intermediate hops become invisible when a router either refuses to send an ICMP TTL expired message in response to an incoming ICMP packet or simply tosses ICMP echo requests altogether.
The behavior of some routers not to return a TTL expired message in response to an ICMP Echo request is due in part to the following text extracted from RFC 792 RFC792:
"The ICMP messages typically report errors in the processing of datagrams. To avoid the infinite regress of messages about messages etc., no ICMP messages are sent about ICMP messages."
Lookup
The Lookup operation enables remote lookup of addresses for a symbolic name as it is, for example, performed by functions getnameinfo() or gethostbyaddr() and lookup of symbolic names for an address as it is, for example, performed by functions getaddrinfo() or gethostbyname(). Note that whatever lookup function is chosen, results are not necessarily consistent with the results of a pure Domain Name Service (DNS) lookup, but may be influenced by local lookup tables or other sources of information. The lookup capability can be used to determine the symbolic name of a hop in a traceroute path. Also, the reverse lookup can be used, for example, for analyzing name lookup problems.
Remote Operations
The MIB modules defined in this document allow a management station to initiate ping, traceroute, and lookup operations remotely. The basic scenario is illustrated by the following diagram.

result of
operation
A management station is the local host from which the remote ping, traceroute, or Lookup operation is initiated using an SNMP request. The managed node is a remote host where the MIBs defined by this memo are implemented. It receives the remote operation via SNMP and performs the actual ping, traceroute, or lookup function.
The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 RFC3410.
Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 RFC2578, STD 58, RFC 2579 RFC2579 and STD 58, RFC 2580 RFC2580.
Structure of the MIBs
This document defines three MIB modules:
o DISMAN-PING-MIB
Defines a ping MIB.
o DISMAN-TRACEROUTE-MIB
Defines a traceroute MIB.
o DISMAN-NSLOOKUP-MIB
Provides access to lookup functions for symbolic names and addresses at a remote host provided, for example, by functions getaddrinfo()/getnameinfo() and gethostbyname()/gethostbyaddr().
The ping and traceroute MIBs are structured to allow creation of ping or traceroute tests that can be set up to issue a series of operations periodically and to generate NOTIFICATIONs to report on test results. Many network administrators have in the past written UNIX shell scripts or command batch files to operate in a fashion similar to the functionality provided by the ping and traceroute MIBs defined within this memo. The intent of this document is to acknowledge the importance of these functions and to provide a standards-based solution.
Ping MIB
The DISMAN-PING-MIB consists of the following components:
o pingMaxConcurrentRequests
o pingCtlTable
o pingResultsTable
o pingProbeHistoryTable
pingMaxConcurrentRequests
The object pingMaxConcurrentRequests enables control of the maximum number of concurrent active requests that an agent implementation supports. It is permissible for an agent either to limit the maximum upper range allowed for this object or to implement this object as read-only with an implementation limit expressed as its value.
pingCtlTable
A remote ping test is started by setting pingCtlAdminStatus to enabled(1). The corresponding pingCtlEntry MUST have been created, and its pingCtlRowStatus set to active(1), prior to starting the test. A single SNMP PDU can be used to create and start a remote ping test. Within the PDU, pingCtlTargetAddress should be set to the target host's address (pingCtlTargetAddressType will default to ipv4(1)), pingCtlAdminStatus to enabled(1), and pingCtlRowStatus to createAndGo(4).
The first index element, pingCtlOwnerIndex, is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 3415 RFC3415, VACM) and that allows a management application to identify its entries. The second index, pingCtlTestName (also an SnmpAdminString), enables the same management application to have multiple requests outstanding.
Using the maximum value for the parameters defined within a pingEntry can result in a single remote ping test's taking at most 15 minutes (pingCtlTimeOut times pingCtlProbeCount), plus whatever time it takes to send the ping request and to receive its response over the network from the target host. Use of the defaults for pingCtlTimeOut and pingCtlProbeCount yields a maximum of 3 seconds to perform a "normal" ping test.
A management application can delete an active remote ping request by setting the corresponding pingCtlRowStatus object to destroy(6).
The contents of the pingCtlTable are preserved across reIPLs (Initial Program Loads) of its agent according the values of each of the pingCtlStorageType objects.
pingResultsTable
An entry in the pingResultsTable is created for a corresponding pingCtlEntry once the test defined by this entry is started.
pingProbeHistoryTable
The results of past ping probes are stored in this table on a per- pingCtlEntry basis. This table is initially indexed by pingCtlOwnerIndex and pingCtlTestName so that the results of a probe relate to the pingCtlEntry that caused it. The maximum number of entries stored in this table per pingCtlEntry is determined by the value of pingCtlMaxRows.
An implementation of this MIB will remove the oldest entry in the pingProbeHistoryTable of the corresponding entry in the pingCtlTable to allow the addition of a new entry once the number of rows in the pingProbeHistoryTable reaches the value specified by pingCtlMaxRows for the corresponding entry in the pingCtlTable. An implementation MUST start assigning pingProbeHistoryIndex values at 1 and wrap after exceeding the maximum possible value, as defined by the limit of this object ('ffffffff'h).
Traceroute MIB
The DISMAN-TRACEROUTE-MIB consists of the following components:
o traceRouteMaxConcurrentRequests
o traceRouteCtlTable
o traceRouteResultsTable
o traceRouteProbeHistoryTable
o traceRouteHopsTable
traceRouteMaxConcurrentRequests
The object traceRouteMaxConcurrentRequests enables control of the maximum number of concurrent active requests that an agent implementation supports. It is permissible for an agent either to limit the maximum upper range allowed for this object or to implement this object as read-only with an implementation limit expressed as its value.
traceRouteCtlTable
A remote traceroute test is started by setting traceRouteCtlAdminStatus to enabled(1). The corresponding traceRouteCtlEntry MUST have been created, and its traceRouteCtlRowStatus set to active(1), prior to starting the test. A single SNMP PDU can be used to create and start a remote traceroute
test. Within the PDU, traceRouteCtlTargetAddress should be set to the target host's address (traceRouteCtlTargetAddressType will default to ipv4(1)), traceRouteCtlAdminStatus to enabled(1), and traceRouteCtlRowStatus to createAndGo(4).
The first index element, traceRouteCtlOwnerIndex, is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 3415 RFC3415, VACM) and that allows a management application to identify its entries. The second index, traceRouteCtlTestName (also an SnmpAdminString), enables the same management application to have multiple requests outstanding.
Traceroute has a much longer theoretical maximum time for completion than ping: basically, 42 hours and 30 minutes (the product of traceRouteCtlTimeOut, traceRouteCtlProbesPerHop, and traceRouteCtlMaxTtl) plus some network transit time! Use of the defaults defined within an traceRouteCtlEntry yields a maximum of 4 minutes and 30 seconds for a default traceroute operation. Clearly, 42 plus hours is too long to wait for a traceroute operation to be completed.
The maximum Time to Live (TTL) value in effect for traceroute determines how long the traceroute function will keep increasing the TTL value in the probe it transmits, hoping to reach the target host. The function ends whenever the maximum TTL is exceeded or the target host is reached. The object traceRouteCtlMaxFailures was created in order to impose a throttle for how long traceroute continues to increase the TTL field in a probe without receiving any kind of response (timeouts). It is RECOMMENDED that agent implementations impose a time limit for how long it allows a traceroute operation to take, relative to how the function is implemented. For example, an implementation that can't process multiple traceroute operations at the same time SHOULD impose a shorter maximum allowed time period.
A management application can delete an active remote traceroute request by setting the corresponding traceRouteCtlRowStatus object to destroy(6).
The contents of the traceRouteCtlTable are preserved across reIPLs (Initial Program Loads) of its agent according to the values of each of the traceRouteCtlStorageType objects.
traceRouteResultsTable
An entry in the traceRouteResultsTable is created upon determining the results of a specific traceroute operation. Entries in this table relate back to the traceRouteCtlEntry that caused the
corresponding traceroute operation to occur. The objects traceRouteResultsCurHopCount and traceRouteResultsCurProbeCount can be examined to determine how far the current remote traceroute operation has reached.
traceRouteProbeHistoryTable
The results of past traceroute probes can be stored in this table on a per-traceRouteCtlEntry basis. This table is initially indexed by traceRouteCtlOwnerIndex and traceRouteCtlTestName so that the results of a probe relate to the traceRouteCtlEntry that caused it. The number of entries stored in this table per traceRouteCtlEntry is determined by the value of traceRouteCtlMaxRows.
An implementation of this MIB will remove the oldest entry in the traceRouteProbeHistoryTable of the corresponding entry in the traceRouteCtlTable to allow the addition of an new entry once the number of rows in the traceRouteProbeHistoryTable reaches the value of traceRouteCtlMaxRows for the corresponding entry in the traceRouteCtlTable. An implementation MUST start assigning traceRouteProbeHistoryIndex values at 1 and wrap after exceeding the maximum possible value, as defined by the limit of this object ('ffffffff'h).
traceRouteHopsTable
The current traceroute path can be stored in this table on a per- traceRouteCtlEntry basis. This table is initially indexed by traceRouteCtlOwnerIndex and traceRouteCtlTestName so that a traceroute path relates to the traceRouteCtlEntry that caused it. A third index, traceRouteHopsHopIndex, enables keeping one traceRouteHopsEntry per traceroute hop. Creation of traceRouteHopsTable entries is enabled by setting the corresponding traceRouteCtlCreateHopsEntries object to true(1).
Lookup MIB
The DISMAN-NSLOOKUP-MIB consists of the following components:
o lookupMaxConcurrentRequests and lookupPurgeTime
o lookupCtlTable
o lookupResultsTable
lookupMaxConcurrentRequests and lookupPurgeTime
The object lookupMaxConcurrentRequests enables control of the maximum number of concurrent active requests that an agent implementation is structured to support. It is permissible for an agent either to limit the maximum upper range allowed for this object or to implement this object as read-only with an implementation limit expressed as its value.
The object lookupPurgeTime provides a method for entries in the lookupCtlTable and lookupResultsTable to be automatically deleted after the corresponding operation is completed.
lookupCtlTable
A remote lookup operation is initiated by performing an SNMP SET request on lookupCtlRowStatus. A single SNMP PDU can be used to create and start a remote lookup operation. Within the PDU, lookupCtlTargetAddress should be set to the entity to be resolved (lookupCtlTargetAddressType will default to ipv4(1)) and lookupCtlRowStatus to createAndGo(4). The object lookupCtlOperStatus can be examined to determine the state of a lookup operation. A management application can delete an active remote lookup request by setting the corresponding lookupCtlRowStatus object to destroy(6).
An lookupCtlEntry is initially indexed by lookupCtlOwnerIndex, which is a type of SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 3415 RFC3415,
VACM) and that also allows for a management application to identify its entries. The lookupCtlOwnerIndex portion of the index is then followed by lookupCtlOperationName. The lookupCtlOperationName index enables the same lookupCtlOwnerIndex entity to have multiple outstanding requests.
The value of lookupCtlTargetAddressType determines which lookup function to perform. Specification of dns(16) as the value of this index implies that a function such as getaddrinfo() or gethostbyname() should be performed to determine the numeric addresses associated with a symbolic name via lookupResultsTable entries. Use of a value of either ipv4(1) or ipv6(2) implies that a function such as getnameinfo() or gethostbyaddr() should be performed to determine the symbolic name(s) associated with a numeric address at a remote host.
lookupResultsTable
The lookupResultsTable is used to store the results of lookup operations. Results to be reported here SHOULD be results of a lookup function that is commonly used by applications at the managed node. This implies that results are not necessarily consistent with the results of a pure DNS lookup at the managed node, but may be influenced by local lookup tables or other sources of information, depending on the configuration of the managed node.
The lookupResultsTable is initially indexed by the same index elements that the lookupCtlTable contains (lookupCtlOwnerIndex and lookupCtlOperationName) but has a third index element, lookupResultsIndex (Unsigned32 textual convention), in order to associate multiple results with the same lookupCtlEntry.
A remote host can be multi-homed and can have multiple symbolic (DNS) names. Therefore, a lookup operation can return multiple IP addresses and multiple symbolic names.
If the lookup operation was performed for a certain address by using getnameinfo() or gethostbyaddr(), for example, then entries in the lookupResultsTable MUST be made for each host name returned. If the lookup operation identifies one hostname as the host's 'official host name', then this name MUST be assigned a lookupResultsIndex of 1.
If a lookup operation was performed for a certain symbolic name by using getaddrinfo() or gethostbyname(), for example, then entries in the lookupResultsTable MUST be made for each address returned. The entries MUST be stored in the order that they are retrieved. Values assigned to lookupResultsIndex MUST start at 1 and increase in order.
An implementation SHOULD NOT retain SNMP-created entries in the lookupResultsTable across reIPLs (Initial Program Loads) of its agent, since management applications need to see consistent behavior with respect to the persistence of the table entries that they create.
Conformance
Each of the three MIB modules defined in this document has two current compliance statements, one for full compliance and one for minimum compliance. The minimum compliance statements are intended to be applied to implementation for devices with very limited resources. The main difference between full and minimum compliance is that for minimum compliance, dynamic creation and deletion of table entries is not required, whereas it is required for full compliance.
In addition, the DISMAN-PING-MIB module and the DISMAN-TRACEROUTE-MIB modules each have a deprecated compliance statement that was current in RFC 2925. Semantically, the new full compliance statements are identical to the deprecated ones. But some of the object groups used in the old compliance statements needed to be split in order to support the new minimal compliance statements.

DESCRIPTION
"To facilitate the provisioning of access control by a
security administrator using the View-Based Access
Control Model (RFC 2575, VACM) for tables in which
multiple users may need to create or
modify entries independently, the initial index is used
as an 'owner index'. Such an initial index has a syntax
of SnmpAdminString and can thus be trivially mapped to a
securityName or groupName defined in VACM, in
accordance with a security policy.
When used in conjunction with such a security policy, all
entries in the table belonging to a particular user (or
group) will have the same value for this initial index.
For a given user's entries in a particular table, the
object identifiers for the information in these entries
will have the same subidentifiers (except for the 'column'
subidentifier) up to the end of the encoded owner index.
To configure VACM to permit access to this portion of the
table, one would create vacmViewTreeFamilyTable entries
with the value of vacmViewTreeFamilySubtree including
the owner index portion, and vacmViewTreeFamilyMask
'wildcarding' the column subidentifier. More elaborate
configurations are possible."

DESCRIPTION
"To facilitate the provisioning of access control by a
security administrator using the View-Based Access
Control Model (RFC 3415, VACM) for tables in which
multiple users may need to create or
modify entries independently, the initial index is used as
an 'owner index'. Such an initial index has a syntax of
SnmpAdminString and can thus be trivially mapped to a
securityName or groupName defined in VACM, in
accordance with a security policy.
When used in conjunction with such a security policy,
all entries in the table belonging to a particular user
(or group) will have the same value for this initial
index. For a given user's entries in a particular
table, the object identifiers for the information in
these entries will have the same subidentifiers (except
for the 'column' subidentifier) up to the end of the
encoded owner index. To configure VACM to permit access
to this portion of the table, one would create
vacmViewTreeFamilyTable entries with the value of
vacmViewTreeFamilySubtree including the owner index
portion, and vacmViewTreeFamilyMask 'wildcarding' the
column subidentifier. More elaborate configurations
are possible."

DESCRIPTION
"To facilitate the provisioning of access control by a
security administrator using the View-Based Access
Control Model (RFC 2575, VACM) for tables in which
multiple users may need to create or
modify entries independently, the initial index is used as
an 'owner index'. Such an initial index has a syntax of
SnmpAdminString and can thus be trivially mapped to a
securityName or groupName defined in VACM, in
accordance with a security policy.
When used in conjunction with such a security policy all
entries in the table belonging to a particular user (or
group) will have the same value for this initial index.
For a given user's entries in a particular table, the
object identifiers for the information in these entries
will have the same subidentifiers (except for the
'column' subidentifier) up to the end of the encoded
owner index. To configure VACM to permit access to this
portion of the table, one would create
vacmViewTreeFamilyTable entries with the value of
vacmViewTreeFamilySubtree including the owner index
portion, and vacmViewTreeFamilyMask 'wildcarding' the
column subidentifier. More elaborate configurations
are possible."

An operation is automatically enabled(1) when its
lookupCtlRowStatus object is transitioned to active(1)

DESCRIPTION
"This object allows entries to be created and deleted
in the lookupCtlTable.
A remote lookup operation is started when an
entry in this table is created via an SNMP set
request and the entry is activated. This
occurs by setting the value of this object
to CreateAndGo(4) during row creation or
by setting this object to active(1) after
the row is created.
A value MUST be specified for lookupCtlTargetAddress
prior to the acceptance of a transition to active(1) state.
A remote lookup operation starts when its entry
first becomes active(1). Transitions in and
out of active(1) state have no effect on the
operational behavior of a remote lookup
operation, with the exception that deletion of
an entry in this table by setting its RowStatus
object to destroy(6) will stop an active
remote lookup operation.
The operational state of a remote lookup operation
can be determined by examination of its
lookupCtlOperStatus object."

-- Lookup Results Table
lookupResultsTable OBJECT-TYPE
SYNTAX SEQUENCE OF LookupResultsEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"Defines the Lookup Results Table for providing
the capability of determining the results of a
operation at a remote host.
One or more entries are added to the
lookupResultsTable when a lookup operation,
as reflected by an lookupCtlEntry, is completed
successfully. All entries related to a
successful lookup operation MUST be added
to the lookupResultsTable at the same time
that the associating lookupCtlOperStatus
object is transitioned to completed(2).
The number of entries added depends on the
results determined for a particular lookup
operation. All entries associated with an
lookupCtlEntry are removed when the
lookupCtlEntry is deleted.
A remote host can be multi-homed and have more than one IP
address associated with it (returned by lookup function),
or it can have more than one symbolic name (returned
by lookup function).
A function such as, for example, getnameinfo() or
gethostbyaddr() is called with a host address as its
parameter and is used primarily to determine a symbolic
name to associate with the host address. Entries in the
lookupResultsTable MUST be made for each host name
returned. If the function identifies an 'official host
name,' then this symbolic name MUST be assigned a
lookupResultsIndex of 1.
A function such as, for example, getaddrinfo() or
gethostbyname() is called with a symbolic host name and is
used primarily to retrieve a host address. The entries
MUST be stored in the order that they are retrieved from
the lookup function. lookupResultsIndex 1 MUST be
assigned to the first entry."

Security Considerations
There are a number of management objects defined in the three MIB modules with a MAX-ACCESS clause of read-write and/or read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. These are the tables and objects and their sensitivity/vulnerability:
o pingMaxConcurrentRequests o traceRouteMaxConcurrentRequests o lookupMaxConcurrentRequests
The MIB modules limit their maximum numbers of concurrent requests by the values of these objects. Unauthorized access to them may lead to an overload of the managed node and to a disruption of other functions of the managed node.
o pingCtlTable o traceRouteCtlTable o lookupCtlTable
All objects in entries of these tables (except index objects) have a MAX-ACCESS clause of read-create. Unauthorized access to these objects can disturb the measurements controlled by the tables. Also, the functions offered by the MIB modules can be misused for illegal data retrieval and for attacking other systems by floods of ping probes, traceroute probes or lookup requests, respectively.
In general, all three, the ping, traceroute, and lookup functions, when used excessively are considered a form of system attack. In the case of ping, sending a system request too often can negatively effect its performance and attempting to connect to what is supposed to be an unused port can be very unpredictable. Excessive use of the traceroute capability can, like ping, negatively affect system performance. The same applies to excessive use of the lookup service, particularly if the lookup cannot be resolved locally. In
insecure environments, it is RECOMMENDED that the MIBs defined within this memo not be supported.
o lookupPurgeTime
Unauthorized access to this object can lead to the deletion of results of lookup operations before they are read by a management system, if the object is set to 0 or small values close to 0. If the object is set to very high values, unauthorized access can lead to a high consumption of resources for storing lookup results.
Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. However, the only information that can be disclosed without encryption is the configuration and results of measurements that are performed by implementations of the MIB modules.
To facilitate the provisioning of access control by a security administrator using the View-Based Access Control Model (VACM), defined in RFC 3415 RFC3415, for tables in which multiple users may need to create or modify entries independently, the initial index is used as an "owner index." Such an initial index has a syntax of SnmpAdminString and can thus be trivially mapped to a securityName or groupName defined in VACM, in accordance with a security policy.
All entries in related tables belonging to a particular user will have the same value for this initial index. For a given user's entries in a particular table, the object identifiers for the information in these entries will have the same subidentifiers (except for the "column" subidentifier) up to the end of the encoded owner index. To configure VACM to permit access to this portion of the table, one would create vacmViewTreeFamilyTable entries with the value of vacmViewTreeFamilySubtree including the owner index portion, and vacmViewTreeFamilyMask 'wildcarding' the column subidentifier. More elaborate configurations are possible. The VACM access control mechanism described above provides control.
SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is
allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module.
It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see RFC3410, section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.
