1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes a set of managed objects that are used
to schedule management operations periodically or at specified dates
and times.
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 [16].
2. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [1].
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
STD16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The
second version, called SMIv2, is described in STD 58, RFC 2578
[5], RFC 2579 [6] and RFC 2580 [7].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
Lingle/Maeng/Mule/Walker [Page 2]
Internet-Draft SIP MIB June 2001
described in RFC 1157 [8]. A second version of the SNMP message
protocol, which is not an Internet standards track protocol, is
called SNMPv2c and described in RFC 1901 [9] and RFC 1906 [10].
The third version of the message protocol is called SNMPv3 and
described in RFC 2572 [11] and RFC 2574 [12].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC 1157 [8]. A second set of protocol
operations and associated PDU formats is described in RFC 1905
[13].
o A set of fundamental applications described in RFC 2573 [14] and
the view-based access control mechanism described in RFC 2575
[15].
A more detailed introduction to the current SNMP Management
Framework can be found in RFC 2570 [20].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined 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. Overview
The Session Initiation Protocol (SIP) [17] is an application-layer
control protocol that can establish, modify and terminate multimedia
sessions or calls. This MIB provides some managed objects for SIP
entities defined in RFC 2543 - User Agent, Proxy server, Redirect
server and Registrar. It is provided as a base for the work within
the working group to define a MIB.
This MIB is intended to provide management of the basic SIP
entities. It provides for monitoring of status and protocol
statistics, as well as for configuration of SIP entities. It also
includes objects for the SIP INFO method [19].
4. Structure of SIP MIB
This memo specifies five MIB modules. They are SIP-MIB-SMI, SIP-
COMMON-MIB, SIP-SERVER-MIB, SIP-UA-MIB and SIP-TC. SIP-MIB-SMI
Lingle/Maeng/Mule/Walker [Page 3]
Internet-Draft SIP MIB June 2001
indicates the root OID of SIP MIB modules. SIP-COMMON-MIB contains
common objects used in all the SIP entities such as Registrars,
Proxy Servers, Redirect Servers and User Agents. SIP-SERVER-MIB and
SIP-UA-MIB includes objects defined for Registrars, Proxy Redirect
servers and User Agents, respectively. SIP-TC defines the textual
conventions used throughout MIB modules.
Each MIB Module contains following groups of objects:
-- SIP-COMMON-MIB: Common to all the SIP entities
sipCommonConfigGroup,
sipCommonStatsGroup,
sipCommonConfigTimerGroup,
sipCommonConfigTimerExtMethodGroup,
sipCommonConfigRetryGroup,
sipCommonConfigRetryExtMethodGroup,
sipCommonStatsRetryGroup,
sipCommonStatsRetryExtMethodsGroup,
sipCommonNotifGroup,
sipCommonStatusCodeNotifGroup.
-- SIP-SERVER-MIB: Groups of objects for Registrars, Proxy and
-- Redirect Servers
sipServerConfigGroup,
sipProxyConfigGroup,
sipProxyStatsGroup,
sipRegistrarConfigGroup,
sipRegistrarStatsGroup.
-- SIP-UA-MIB: Groups of objects for User Agents
sipUAConfigGroup
It is required to implement SIP-COMMON-MIB together with its own MIB
module in Registrars, Proxy Servers, Redirect Servers and User
Agents. For instance, a SIP Registrar will need four MIB modules,
SIP-MIB-SMI, SIP-COMMON-MIB, SIP-SERVER-MIB, and SIP-TC in order to
provide a complete set of objects. If a device has more than one sip
entity or multiple instances of the same entity, it should implement
multiple SIP modules. Section 4.2 describes handling of multiple
instances in detail.
4.1. Textual Conventions
The data type SipTransportProtocol is used as textual conventions in
this document. These textual conventions have NO effect on either
the syntax or the semantics of any managed object. Objects defined
using these conventions are always encoded by means of the rules
that define their primitive type. Hence, no changes to the SMI or
the SNMP are necessary to accommodate these textual conventions,
which are adopted merely for the convenience of readers.
Lingle/Maeng/Mule/Walker [Page 4]
Internet-Draft SIP MIB June 2001
4.2. Relationship to Other MIB
There is a requirement to be able to support multiple instances of
SIP MIB modules in the context of a single system having a single
SNMP agent.
It is also possible to have multiple instances of a particular type
of SIP entity running on the same system. For example, there may be
Registrars for different domains with completely different
behaviors.
While there are separate MIB modules defined for SIP User Agents and
SIP servers, there is also a "common" MIB module expected to be
supported by every SIP entity. Further, all SIP entities are either
acting as a UAC, UAS or perhaps both. So a SIP Proxy Server must
support the SIP-SERVER-MIB and SIP-COMMON-MIB modules. Likewise,
the Registrar must support the SIP-SERVER-MIB and SIP-COMMON-MIB
modules. Here we have the requirement for supporting multiple
instances of a particular MIB module in one system.
This requirement is solved by using the framework provided by the
NETWORK-SERVICES-MIB, RFC 2788 [18]. A device implementing the SIP
MIB MUST support the NETWORK-SERVICES-MIB and, at a minimum, it MUST
support the applIndex and applName objects in applTable. The
following applName conventions will be adopted:
o for a SIP Proxy entity, applName must be equal to "sip_proxy"
o for a SIP Redirect entity, applName must be equal to
"sip_redirect"
o for a SIP Registrar entity, applName must be equal to
"sip_registrar"
o for a SIP User Agent entity, applName must be equal to
"sip_ua"
o for a SIP entity acting in any combination of Proxy, Redirect,
or Registrar, AND wishing to support only a single instance of
the SIP-COMMON-MIB, the applName for the combined server
entity must reflect the appropriate combination. For example,
"sip_proxy_redirect" or "sip_proxy_registrar".
Additionally, the following objects may be supported in applTable.
If they are, the object values SHOULD be populated as follows:
o applVersion: version of the SIP application; if the SIP
protocol version is used, the value MUST be as defined in SIP
[17], section 4.3.1.
o applUptime: value must be identical to sipServiceStartTime
defined in the SIP-COMMON module,
o applOperStatus: value should reflect the operational status
defined in sipServiceOperStatus, at least by means of a
mapping,
o applLastChange: value must be identical to
sipServiceLastChange defined in the SIP-COMMON module.
Lingle/Maeng/Mule/Walker [Page 5]
Internet-Draft SIP MIB June 2001
Note: There are a number of other objects in the applTable. They
are not included for the sake of brevity and for the fact that they
do not enhance the concept being presented.
Example 1: The table below illustrates how it would conceptually
appear in a system acting as both, a Proxy and Registrar server and
wishing to maintain separate SIP-COMMON-MIB instances.
The NETWORK-SERVICES-MIB applTable would be populated as follows:
applIndex | applName | applDescription
----------+-----------------+------------------------------
1 | "sip_proxy" | "ACME SIP Proxy"
----------+-----------------+------------------------------
2 | "sip_registrar" | "ACME SIP Registrar"
----------+-----------------+------------------------------
The SIP-COMMON-MIB sipCommonCfgTable would have two rows: one for
the proxy (applIndex=1) and one for the registrar (applIndex=2).
The SIP-SERVER-MIB tables would, however, only be populated with one
row indexed by applIndex=1 and applIndex=2 respectively if the
server provides either proxy or registrar.
SIP-COMMON-MIB sipCommonCfgTable might be populated as:
applIndex | sipProtocolVersion | sipServiceOperStatus | ...
----------+--------------------+----------------------+----
1 | "SIP/2.0" | up(1) |
----------+--------------------+----------------------+----
2 | "SIP/2.0" | restarting(6) |
----------+--------------------+----------------------+----
while sipProxyCfgTable in SIP-SERVER-MIB is populated as:
applIndex | sipRequestMaxExpires | sipProxyStateful | ...
----------+----------------------+------------------+----
1 | 3600 | false |
----------+----------------------+------------------+----
and sipRegUserTable in SIP-SERVER-MIB is populated as:
applIndex | sipUserIndex | sipUserUri | ...
----------+--------------+--------------------------+----
2 | 1 | drwalker@ss8.com |
----------+--------------+--------------------------+----
2 | 2 | jmaeng@ipdialog.com |
----------+--------------+--------------------------+----
2 | 3 | klingle@cisco.com |
----------+--------------+--------------------------+----
2 | 4 | jfm@clarent.com |
----------+--------------+--------------------------+----
Lingle/Maeng/Mule/Walker [Page 6]
Internet-Draft SIP MIB June 2001
Example 2: The next table illustrates how it would conceptually
appear in a system acting as both, a Proxy and Registrar server and
wishing to share a single instance of SIP-COMMON-MIB.
The NETWORK-SERVICES-MIB applTable would be populated as follows:
applIndex | applName | applDescription
----------+----------------------+---------------------------
1 | "sip_proxy_registrar"| "ACME SIP Proxy&Registrar"
----------+----------------------+---------------------------
The SIP-COMMON-MIB sipCommonCfgTable would have only one row to
cover both the proxy and the registrar.
SIP-COMMON-MIB sipCommonCfgTable might be populated as:
applIndex | sipProtocolVersion | sipServiceOperStatus | ...
----------+--------------------+----------------------+----
1 | "SIP/2.0" | up(1) |
----------+--------------------+----------------------+----
while sipProxyCfgTable in SIP-SERVER-MIB is populated as:
applIndex | sipRequestMaxExpires | sipProxyStateful | ...
----------+----------------------+------------------+----
1 | 3600 | false |
----------+----------------------+------------------+----
and sipRegUserTable in SIP-SERVER-MIB is populated as:
applIndex | sipUserIndex | sipUserUri | ...
----------+--------------+--------------------------+----
1 | 1 | drwalker@ss8networks.com |
----------+--------------+--------------------------+----
1 | 2 | jmaeng@ipdialog.com |
----------+--------------+--------------------------+----
1 | 3 | klingle@cisco.com |
----------+--------------+--------------------------+----
1 | 4 | jfm@clarent.com |
----------+--------------+--------------------------+----
The NETWORK-SERVICES-MIB assocTable is not considered a requirement
for SIP systems. It is not a mandatory group for NETWORK-SERVICES-
MIB compliance.

DESCRIPTION
"Initial version of Session Initiation Protocol (SIP)
Common MIB module. This module defines objects which
Lingle/Maeng/Mule/Walker [Page 10]
Internet-Draft SIP MIB June 2001
may be common to all SIP entities.
SIP is an application-layer signalling protocol for
creating, modifying and terminating multimedia
sessions with one or more participants. These sessions
include Internet multimedia conferences and Internet
telephone calls. SIP is defined in RFC 2543 (March
1999).
This MIB is defined for the managing objects which are
common to SIP User Agents (UAs), Proxy and Redirect
Servers, and Registrars. Objects specific to each of
these entities may be managed using entity specific
MIBs defined in other modules.
A User Agent is an application that contains both a
User Agent Client (UAC) and a User Agent Server (UAS).
A UAC is an application that initiates a SIP request.
A UAS is an application that contacts the user when a
SIP request is received and that returns a response on
behalf of the user. The response accepts, rejects, or
redirects the request.
A Proxy Server acts as both a client and a server.
It accepts requests from other clients, either
responding to them or passing them on to other
servers, possibly after modification.
A Redirect Server accepts requests from clients and
returns zero or more addresses to that client. Unlike
a Proxy server it does not initiate requests. Unlike
a User Agent Server it does not accept calls.
A Registrar is a server that accepts REGISTER
requests. A Registrar is typically co-located with a
Proxy or Redirect Server."

DESCRIPTION
"This table contains a list of the non-standard features
supported by each SIP entity in this system, and which
may be required by a peer. Definition of such features is
outside the scope of SIP, which only provides mechanisms
whereby support for specific features may be signalled or
requested.
For example, a user agent client may require that a server
support the 'com.example.billing' feature, which it would
indicate in a Require header. Such a client would have
a row in its sipFtrSupportedTable containing the string
'com.example.billing'. Similarly, a server which is
capable of handling requests for such features would list
the string in its sipFtrSupportedTable.
If a server does not support the required feature
(indicated in a Require header to a UAS, or in a Proxy-
Require to a proxy server), the server returns a 420 Bad
Extension listing the feature in an Unsupported header.
Normally the list of such features supported by an entity
is static (i.e. will not change over time)."

"Initial version of Session Initiation Protocol (SIP)
User Agent (UA) MIB module.
SIP is an application-layer signalling protocol for
creating, modifying and terminating multimedia
sessions with one or more participants. These sessions
include Internet multimedia conferences and Internet
telephone calls. SIP is defined in RFC 2543 (March
1999).
A User Agent is an application that contains both a
User Agent Client (UAC) and a User Agent Server (UAS).
A UAC is an application that initiates a SIP request.
A UAS is an application that contacts the user when a
SIP request is received and that returns a response on
behalf of the user. The response accepts, rejects, or
redirects the request."

SIP is an application-layer signalling protocol for

sessions with one or more participants. These sessions
include Internet multimedia conferences and Internet
telephone calls. SIP is defined in RFC 2543 (March

This MIB is defined for the management of SIP Proxy,
Redirect, and Registrar Servers.
A Proxy Server acts as both a client and a server.
It accepts requests from other clients, either
responding to them or passing them on to other
servers, possibly after modification.
A Redirect Server accepts requests from clients and
returns zero or more addresses to that client. Unlike
a Proxy server it does not initiate requests. Unlike
a User Agent Server it does not accept calls.
A Registrar is a server that accepts REGISTER
requests. A Registrar is typically co-located with a
Proxy or Redirect Server."

recursive search on the Contacts provided in 3xx
redirects.
If the value of this object is TRUE, a recursive search is
performed. If the value is FALSE, no search is performed,
the 3xx response is sent upstream towards the source of
the request."

DESCRIPTION
"The object specifies whether or not the Server provides
alternative Contacts in 3xx and 485 responses.
If the value of this object is TRUE, the server inserts a
list of alternative URLs into a Contact header where the
request Originator may possibly find the desired called
party. If the value is FALSE, the server doesn't add
Contact information to 3xx and 485 responses.
Note that the policies of a server may limit the
particular alternatives that are returned when this object
is TRUE."

6. Changes from previous drafts
o Changes from draft-ietf-sip-mib-02.txt
The following changes were made based on review comments to the
previous version of the draft.
In general
o Eliminated the SIP-MIB-SMI modules. Each MIB module will now
get it's own IANA OID.
o Top-level OID subtrees restructured in each MIB.
o General cleanup/removal of "placeholder" OID subtrees
for object groups and notifications that never materialized.
Regarding SIP-COMMON-MIB
o Removed sipCfgInitialTimerAck.
o Removed sipCfgRetryAck.
o Removed sipStatsRetryAcks.
o sipCommonStatsRetryExtMethodEntry was missing its INDEX
clause.
o sipNumUnsupportedUris OID was "5" when it was the
only object in the table. OID is now "1".
o High-level OID structure of the MIB is now sequential.
o Incorrect object descriptor for sipCfgInitialTimerRsp
inconsistent with reference in compliance section.
o Inconsistencies between sipCommonStatsRetryGroup definition
and SipCommonStatsRetryEntry OBJECT-TYPE corrected.
o sipNotifApplIndex was not in any object group in the
conformance section.
Regarding SIP-SERVER-MIB
o Removed sipInformationTryingInterval.
o Removed sipRxProxyAuthTable.
o Removed sipRegRespHasContacts.
o Removed sipRegContactDfltExpiryDate.
o Removed sipRegContactDfltExpiryDuration.
o Removed sipUserPassword.
o sipRequestMaxExpires DESCRIPTION changed to no
longer specifically mention 400 response.
o sipProxyStateful object descriptor changed to
sipProxyStatefullness and the SYNTAX changed
from TruthValue to an enumerated INTEGER.
o sipProxyStateTimeout DESCRIPTION changed to now reflect only
INVITE.
o Gauge32 was not being IMPORTed.
o sipServerContactDfltAction showed up in conformance
and other object descriptions in an older form.
o sipServerHost replaced with InetAddressType/InetAddress
object pair (sipServerHostAddrType & sipServerHostAddr).
Regarding SIP-UA-MIB
Lingle/Maeng/Mule/Walker [Page 80]
Internet-Draft SIP MIB June 2001
o IMPORTed Unsigned32 to support sipUACfgSipServerAddrIndex.
o sipUACfgSipServerEntry was referencing the wrong
auxilliary object and listing that object in the conformance
section.
o sipUACfgSipServerEntry listed sipUACfgSipServerStatus
when it should have been listing sipUACfgSipServerAddrStatus.
o SIP-UA-MIB IMPORTed Counter32, but never used it.
Removed the IMPORT of Counter32.
7. Security Considerations
There are a number of management objects defined in this MIB that
have 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.
The managed objects in this MIB contain sensitive information since,
collectively, they allow tracing and influencing of connections in
SIP entities and provide information of their connection
characteristics.
It is thus important to control even GET access to these objects and
possibly to even encrypt the values of these objects when sending
them over the network via SNMP. Not all versions of SNMP provide
features for such a secure environment.
SNMPv1 by itself is not a secure environment. 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.
It is recommended that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model RFC 2574 [12] and the View-based
Access Control Model RFC 2575 [15] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, 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.
