Abstract
This memo defines a Management Information Base (MIB) for performing
performance monitoring of Service Level Agreements (SLAs) defined via
policy definitions. The MIB defined herein focuses on defining a set of
objects for monitoring SLAs and not on replication of the content of
policy definitions.
The MIB defined by this document is based upon the content of "Schema
for Service Level Administration of Differential Services and Integrated
Services in Networks", refer to [19].

1.0 Introduction
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, reference [13].
This document is a product of the Internet Engineering Task Force
(IETF). Its purpose is to define a MIB module for performance
management of Service Level Agreements (SLAs). An SLA is defined via
policy. There are a number of methods that exist for how policy is
defined and administered. Definition of these methods is considered out
side of the scope of this document. For modeling the contents of this
MIB a policy definition is considered to consist of a set of profiles
that select the conditions for when a policy action should be applied.
Refer to "Schema for Service Level Administration of Differential
Services and Integrated Services in Networks" [19] for a definition of
policy, traffic profile and action.
The SLAPM-MIB is structured primarily to enable monitoring policy
actions at a system. A system can be either an edge device (end-system)
or an interior device or node (e.g. router).
2.0 The SNMP Network Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2271 [7].
White, Kenneth Expires December 1998 [Page 2]
Internet Draft SLAPM-MIB August 19, 1998
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in RFC
1155 [14], RFC 1212 [15] and RFC 1215 [16]. The second version,
called SMIv2, is described in RFC 1902 [3], RFC 1903 [4] and RFC
1904 [5].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in RFC 1157 [1]. A second version of the SNMP message
protocol, which is not an Internet standards track protocol, is
called SNMPv2c and described in RFC 1901 [17] and RFC 1906 [18].
The third version of the message protocol is called SNMPv3 and
described in RFC 1906 [18], RFC 2272 [8] and RFC 2274 [10].
o Protocol operations for accessing management information. The first
set of protocol operations and associated PDU formats is described
in RFC 1157 [1]. A second set of protocol operations and associated
PDU formats is described in RFC 1905 [6].
o A set of fundamental applications described in RFC 2273 [9] and the
view-based access control mechanism described in RFC 2275 [11].
Managed objects are accessed via a virtual information store, termed the
Management Information Base or MIB. Objects in the MIB are defined
ore, using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A MIB
conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.
3.0 Structure of the MIB
The SLAPM-MIB consists of the following components:
o Global simple objects
o slapmPolicyStatsTable
o slapmPolicyMonitorTable
o slapmTcpConnTable and slapmUdpTable
Refer to the compliance statement defined within SLAPM-MIB for a
definition of what objects MUST be implemented by all systems as opposed
to those that MUST be implemented by host systems only.
White, Kenneth Expires December 1998 [Page 3]
Internet Draft SLAPM-MIB August 19, 1998
3.1 Global simple objects
Global objects defined within SLAPM-MIB:
o slapmSpinLock
Enables multiple management application access to SLAPM-MIB. An
agent MUST implement the slapmSpinLock object to enable management
applications to coordinate their use of the SLAPM-MIB. Management
application use of slapmSpinLock is OPTIONAL.
o slapmPolicyQueryCount, slapmPolicyAccessCount,
slapmPolicySuccessCount, and slapmPolicyNotFoundCount
Basic statistics on the amount of policy directory access that has
occured at a system.
o slapmPolicyPurgeTime
Used to prevent the entries in various SLAPM-MIB tables that relate
to a policy definition from immediately being deleted when the
corresponding policy definition no longer exists. This gives
management applications time to discover this condition and close
out any polled based interval data that may be being collected.
Refer to the OBJECT description for slapmPolicyPurgeTime for a more
precise description of this function.
3.2 slapmPolicyStatsTable
The slapmPolicyStatsTable is the main table defined by SLAPM-MIB. One
slapmPolicyStatsEntry exists for each SLA traffic profile per policy
definition. The structure of indexing for slapmPolicyStatsTable assumes
that it is permissible for a policy to consist of a set of traffic
profiles. Systems that allow only a single traffic profile to be
specified per policy definition should still use the name of the traffic
profile as the second index into slapmPolicyStatsTable in order to
conform to SLAPM-MIB. Use of a zero-length octet string to indicate
this condition is NOT allowed.
SLAPM-MIB also assumes that only a single action can be defined for any
single policy definition and hence an action's name doesn't need to be
reflected in table indexing. p.This table provides basic statistics on
the set of policy traffic profiles known at a system. Entries in this
table are not administered via SNMP. An agent implementation for this
table MUST reflect its current set of policy definitions via table
entries. The mechanisms for policy administration are outside of the
scope of this memo.
3.3 slapmPolicyMonitorTable
The slapmPolicyMonitorTable provides a method of monitoring the effect
of SLA policy being used at a system. A management application creates
an slapmPolicyMonitorEntry for each collection that it requires. The
White, Kenneth Expires December 1998 [Page 4]
Internet Draft SLAPM-MIB August 19, 1998
value of the BITS slapmPolicyMonitorControl object determines what type
of collection occurs:
o monitorMinRate(0)
Use the value of slapmPolicyMonitorInterval as the interval to
determine current traffic rate, slapmPolicyMonitorCurrentInRate plus
slapmPolicyMonitorCurrentOutRate, that can be compared to
slapmPolicyMonitorMinRateLow for determining when to generate a
slapmMinRateNotAchieved notification. The notification
slapmMinRateOkay is generated when the problem is resolved. This
can be determined by comparing the current rate to
slapmPolicyMonitorMinRateHigh.
o monitorMaxRate(1)
Use the value of slapmPolicyMonitorInterval as the interval to
determine current traffic rate, slapmPolicyMonitorCurrentInRate plus
slapmPolicyMonitorCurrentOutRate, that can be compared to
slapmPolicyMonitorMaxRateHigh for determining when to generate a
slapmMaxRateExceeded notification. The notification slapmMaxRateOkay
is generated when the problem is resolved. This can be determined
by comparing the current rate to slapmPolicyMonitorMaxRateLow.
o monitorMaxDelay(2)
Use the value of slapmPolicyMonitorInterval as the interval to
determine the current delay. This can be calculated by averaging
the round trip times for all TCP connections associated with the
policy definition. Compare this value to
slapmPolicyMonitorMaxDelayHigh for determining when to generate a
slapmMaxDelayExceeded notification. The notification
slapmMaxDelayOkay is generated when the problem is resolved. This
can be determined by comparing the current rate to
slapmPolicyMonitorMaxDelayLow.
The index element slapmPolicyMonitorOwnerIndex is used as the first
index in slapmPolicyMonitorTable in order to enable SNMPv3 VACM security
control. The slapmPolicyMonitorTable is the only table that supports
SNMP RowStatus operations.
3.4 slapmTcpConnTable and slapmUdpTable
Entries are made into slapmTcpConnTable or slapmUdpTable to indicate
actual policy usage and to provide general statistics on a TCP
connection or UDP listener level.

STATUS current
DESCRIPTION
"The purpose of this object is to define the amount
of time (in seconds) to wait before removing an
slapmPolicyStatsEntry when a system detects that the
associated policy definition has been deleted.
This gives any polling management applications
time to complete their last poll before an entry is
removed. An slapmPolicyStatsEntry enters the
deleteNeeded(3) state via slapmPolicyStatsOperStatus
when a system first detects that the entry needs
to be removed.
Once an slapmPolicyStatsEntry has becomes eligible for
deletion (slapmPolicyPurgeTime has expired) it is
removed as long as there are no dependent entries in
the slapmPolicyMonitorTable. An slapmPolicyStatsEntry
enters the deleted(4) state as defined by
slapmPolicyStatsOperstatus when it needs to be deleted
but can't due to dependent slapmPolicyMonitorTable
entries. A slapmPolicyDeleteNeeded notification
is generated when this condition is detected.
A value of 0 for this option disables this function and
results in either the purging of slapmPolicyTable entries
upon transition into deleteNeeded(3) state or generation
of a slapmPolicyDeleteNeeded notification."

DESCRIPTION
"To facilitate the provisioning of access control by a security
administrator using the View-Based Access Control Model (RFC 2275,
VACM) for tables in which multiple users may need to independently
create or modify entries, 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
as defined in VACM, in accordance with a security policy.
All entries in that table 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."

STATUS current
DESCRIPTION
"The threshold for generating a slapmMaxRateExceeded
notification, signalling that a monitored maximum transfer
rate has been exceeded. The objects slapmPolicyMonitorCurrentInRate
and slapmPolicyMonitorCurrentOutRate are summed when compared
to the value of this object.
A slapmMaxRateExceeded notification is not generated again
for an slapmPolicyMonitorEntry until the maximum transfer rate
fails below slapmPolicyMonitorMaxRateLow (a slapmMaxRateOkay
notification is then transmitted) and then raises above
slapmPolicyMonitorMaxRateHigh. This behavior reduces the
slapmMaxRateExceeded notifications that are transmitted.
A value of zero for this object is returned when the
slapmPolicyMonitorControl monitorMaxRate(1) is not
enabled. When enabled the default value for this object
is the max rate value specified in the associated
action definition plus 10%. If the action definition
doesn't have a max rate defined then there is no
default for this object and a value MUST be specified
prior to activating this entry when monitorMaxRate(1)
is selected."

is the max rate value specified in the associated
action definition minus 10%. If the action definition

5.0 Security Considerations
Certain management information defined in this MIB may be considered
sensitive in some network environments. Therefore, authentication of
received SNMP requests and controlled access to management information
SHOULD be employed in such environments. The method for this
authentication is a function of the SNMP Administrative Framework, and
has not been expanded by this MIB.
It is RECOMMENDED that creation of entries in the
slapmPolicyMonitorTable not be allowed in insecure environments.
6.0 Intellectual Property
The IETF takes no position regarding the validity or scope of any
intellectual property or other rights that might be claimed to pertain
to the implementation or use of the technology described in this
document or the extent to which any license under such rights might or
might not be available; neither does it represent that it has made any
effort to identify any such rights. Information on the IETF's
procedures with respect to rights in standards-track and
standards-related documentation can be found in BCP-11. Copies of
claims of rights made available for publication and any assurances of
licenses to be made available, or the result of an attempt made to
obtain a general license or permission for the use of such proprietary
rights by implementers or users of this specification can be obtained
from the IETF Secretariat.
The IETF invites any interested party to bring to its attention any
copyrights, patents or patent applications, or other proprietary rights
which may cover technology that may be required to practice this
