1. Introduction
The CAPWAP Protocol [RFC5415] defines a standard, interoperable
protocol, which enables an Access Controller (AC) to manage a
collection of Wireless Termination Points (WTPs).
This document defines a MIB module that can be used to manage the
CAPWAP implementations. This MIB module covers both configuration
and WTP status-monitoring aspects of CAPWAP, and provides a way to
reuse MIB modules for any wireless technology. It presented as a
basis for future work on a SNMP management of the CAPWAP protocol.
2. 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].
3. Terminology
This document uses terminology from the CAPWAP Protocol specification
[RFC5415] and the Architecture Taxonomy for CAPWAP [RFC4118].
Access Controller (AC): The network entity that provides WTP access
to the network infrastructure in the data plane, control plane,
management plane, or a combination therein.
Wireless Termination Point (WTP): The physical or network entity that
contains an radio frequency (RF) antenna and wireless physical layer
(PHY) to transmit and receive station traffic for wireless access
networks.
Control And Provisioning of Wireless Access Points (CAPWAP): It is a
generic protocol defining AC and WTP control and data plane
communication via a CAPWAP protocol transport mechanism. CAPWAP
control messages, and optionally CAPWAP data messages, are secured
using Datagram Transport Layer Security (DTLS) [RFC4347].
Shi, et al. Informational [Page 3]
RFC 5833 CAPWAP Protocol Base MIB May 2010
CAPWAP Control Channel: A bi-directional flow defined by the AC IP
Address, WTP IP Address, AC control port, WTP control port, and the
transport-layer protocol (UDP or UDP-Lite) over which CAPWAP control
packets are sent and received.
CAPWAP Data Channel: A bi-directional flow defined by the AC IP
Address, WTP IP Address, AC data port, WTP data port, and the
transport-layer protocol (UDP or UDP-Lite) over which CAPWAP data
packets are sent and received.
Station (STA): A device that contains an interface to a wireless
medium (WM).
Split and Local MAC: The CAPWAP protocol supports two modes of
operation: Split and Local MAC (medium access control). In Split MAC
mode, all Layer 2 wireless data and management frames are
encapsulated via the CAPWAP protocol and exchanged between the AC and
the WTPs. The Local MAC mode allows the data frames to be either
locally bridged or tunneled as 802.3 frames.
Wireless Binding: The CAPWAP protocol is independent of a specific
WTP radio technology, as well its associated wireless link-layer
protocol. Elements of the CAPWAP protocol are designed to
accommodate the specific needs of each wireless technology in a
standard way. Implementation of the CAPWAP protocol for a particular
wireless technology MUST define a binding protocol for it, e.g., the
binding for IEEE 802.11, provided in [RFC5416].
Autonomous Wireless Local Area Network (WLAN) Architecture: It is the
traditional autonomous WLAN architecture, in which each WTP is a
single physical device that implements all the wireless services.
Centralized WLAN Architecture: It is an emerging hierarchical
architecture utilizing one or more centralized controllers for
managing a large number of WTP devices. It can be said that the full
wireless functions are implemented across multiple physical network
devices, namely, the WTPs and ACs.

RFC 5833 CAPWAP Protocol Base MIB May 2010
5. Overview
5.1. Requirements and Constraints
The CAPWAP Protocol MIB module (CAPWAP-BASE-MIB) is designed to:
- Support centralized management and monitoring of WTPs from the AC
in combination with the CAPWAP protocol;
- Allow operators to make configurations for WTPs before and after
they connect to the AC;
- Support querying of CAPWAP protocol parameters;
- Support displaying of WTPs' current states and configurations;
- Provide basic property information about the AC, WTPs, radios, and
stations, and their relationships;
- Provide counters for events on WTPs and radios such as reboot and
hardware failure;
- Provide various notifications such as channel up and join failure.
5.2. Wireless Binding MIB Modules
Other Standards Development Organizations (SDOs), such as IEEE, have
already defined MIB modules for a specific wireless technology, e.g.,
IEEE 802.11 MIB module [IEEE.802-11.2007]. Such MIB modules are
called wireless binding MIB modules.
5.3. Design Objectives
This document introduces a mechanism to avoid redefining MIB objects
in the existing MIB modules for a specific wireless technology, in
other words, a mechanism to reuse wireless binding MIB modules
defined by other SDOs.
In summary, the CAPWAP-BASE-MIB module has the following design
objectives:
- To implement an architecture that uses SNMP for the management and
control of wireless networks, and answering the operator's
requirements for centralized management, whatever the wireless
devices are configured and deployed (centralized, autonomous, or
some mix);
- To be consistent with the CAPWAP protocol;
Shi, et al. Informational [Page 5]RFC 5833 CAPWAP Protocol Base MIB May 2010
- To be independent of any wireless technologies and be able to
reuse wireless binding MIB modules defined by other SDOs;
- To enable interoperability between vendors;
- To meet the management requirements for the centralized WLAN
architecture.
5.4. Design Idea
The basic design idea of the CAPWAP-BASE-MIB module is:
- The SNMP agent MUST be run on the AC devices and is not REQUIRED
on the WTP devices. It follows the same model as the CAPWAP
protocol: Centralized Control.
- It is designed to accommodate the specific needs of each wireless
technology in a standard way. It is independent of any wireless
technologies.
- The ifIndex [RFC2863] is used as a common index for corresponding
interfaces in the CAPWAP-BASE-MIB and the MIB modules of specific
wireless technologies.
- The operator could manage and control the centralized WLAN
architectures using multiple MIB modules defined by multiple SDOs,
while keeping them loosely coupled.
5.5. Mechanism of Reusing Wireless Binding MIB Modules
For any wireless technology, the configuration and management of
radios are very important. As usual, wireless binding MIB modules
support radio management on their own. For example, the MIB tables
such as the dot11OperationTable [IEEE.802-11.2007] are able to
support WTP radio configuration. These tables use the ifIndex as the
index, and work well under autonomous WLAN architecture.
To reuse such wireless binding MIB modules is very important to
centralized WLAN architectures. According to [RFC5415], a specific
PHY radio could be identified by the combination of the identifiers
of the WTP and radio (WTP ID + Radio ID), so the key point is to make
use of the ifIndex idea and find a way to maintain the mappings
between 'WTP ID + radio ID' and the ifIndex. As a generic mechanism,
an ifIndex can identify an interface in an abstract way, and it does
NOT care for the interface's PHY location (either on the WTP or AC).
The AC can have WTP Virtual Radio Interfaces to logically represent
PHY radios on the WTP. From the operator's perspective, it appears
that PHY radios are located on the AC, and the PHY location of the
Shi, et al. Informational [Page 6]RFC 5833 CAPWAP Protocol Base MIB May 2010
WTP (radio) is hidden. The operator can operate radios through MIB
tables with the ifIndex of a WTP Virtual Radio Interface. As a type
of abstract interface, the WTP Virtual Radio Interface could be used
by any wireless technology such as IEEE 802.11 and 802.16. The
capwapBaseWirelessBindingTable in the CAPWAP-BASE-MIB module is used
to store the mappings between the 'WTP ID + Radio ID' and the
ifIndex.
5.6. CAPWAP Protocol Wireless Binding MIB Module
According to the CAPWAP Protocol specification [RFC5415], when
defining a binding for wireless technologies, the authors MUST
include any necessary definitions for technology-specific messages
and all technology-specific message elements for those messages. A
CAPWAP binding protocol is required for a specific wireless binding
technology, e.g., the protocol of [RFC5416] for IEEE 802.11 binding.
Sometimes, not all the technology-specific message elements in a
CAPWAP binding protocol have MIB objects defined by other SDOs. For
example, the protocol of [RFC5416] defines WLAN management. The WLAN
refers to a logical component instantiated on a WTP device. A single
physical WTP MAY operate a number of WLANs. Also, Local or Split MAC
modes could be specified for a WLAN. The MAC mode for a WLAN is not
in the scope of IEEE 802.11 [IEEE.802-11.2007]. In such cases, in
addition to the existing wireless binding MIB modules defined by
other SDOs, a CAPWAP protocol wireless binding MIB module is required
to be defined for a wireless binding, e.g, the CAPWAP Protocol
Binding MIB for IEEE 802.11 [RFC5834].
5.7. WTP Profile
In a centralized WLAN architecture, a WTP profile is used to make
configurations such as a static IP address for a WTP before and after
it connects to the AC. It MUST contain the Base MAC address
[RFC5415] of the WTP because the CAPWAP message received from the WTP
contains the Base MAC address and the AC uses this Base MAC address
to find the corresponding WTP profile.
Section 4.6.40 of [RFC5415] omits indicating that the WTP's Base MAC
address MUST be included in the WTP Board Data message element. This
is a known errata item [Err1832] and should be fixed in any future
revision of RFC 5415.
Another important function of WTP profile is to trigger the creation
of WTP Virtual Radio Interfaces on the AC. To implement this
function, a WTP profile MUST include the WTP's model number
[RFC5415], which reflects the number of PHY radios on the WTP. In
this way, the creation of a WTP profile triggers the AC to
Shi, et al. Informational [Page 7]
RFC 5833 CAPWAP Protocol Base MIB May 2010
automatically create the same number of WTP Virtual Radio Interfaces
corresponding to the WTP's PHY radios without manual intervention.
With the ifIndexes of WTP Virtual Radio Interfaces, the operator
could configure and manage the WTP's PHY radios through the wireless
binding MIB modules.
6. Structure of the MIB Module
The MIB objects are derived from the CAPWAP protocol document
[RFC5415].
1) capwapBaseAcNameListTable
The AC name list table is used to configure the AC name list.
2) capwapBaseMacAclTable
The ACL table is used to configure stations' Access Control Lists
(ACLs).
3) capwapBaseWtpProfileTable
The WTP profile table is used to configure WTP profiles for WTPs
to be managed before they connect to the AC. An operator could
change a WTP's current configuration by changing the values of
parameters in the corresponding WTP profile, then the WTP could
get the new configuration through the CAPWAP control channel.
4) capwapBaseWtpStateTable
The state table of WTPs is used to indicate the AC's CAPWAP FSM
state for each WTP, and helps the operator to query a WTP's
current configuration.
5) capwapBaseWtpTable
The WTP table is used to display properties of the WTPs in running
state.
6) capwapBaseWirelessBindingTable
The wireless binding table is used to display the mappings between
WTP Virtual Radio Interfaces and PHY radios, and the wireless
binding type for each PHY radio.
Shi, et al. Informational [Page 8]RFC 5833 CAPWAP Protocol Base MIB May 2010
7) capwapBaseStationTable
The station table is used for providing stations' basic property
information.
8) capwapBaseWtpEventsStatsTable
The WTP events statistic table is used for collecting WTP reboot
count, link failure count, hardware failure count and so on.
9) capwapBaseRadioEventsStatsTable
The radio events statistic table is used for collecting radio
reset count, channel change count, hardware failure count, and so
on.
7. Relationship to Other MIB Modules
7.1. Relationship to SNMPv2-MIB Module
The CAPWAP-BASE-MIB module does not duplicate the objects of the
'system' group in the SNMPv2-MIB [RFC3418] that is defined as being
mandatory for all systems, and the objects apply to the entity as a
whole. The 'system' group provides identification of the management
entity and certain other system-wide data.
7.2. Relationship to IF-MIB Module
The Interfaces Group [RFC2863] defines generic managed objects for
managing interfaces. This memo contains the media-specific
extensions to the Interfaces Group for managing WTP PHY radios that
are modeled as interfaces.
The IF-MIB module is required to be supported on the AC. Each PHY
radio on the WTP corresponds to a WTP Virtual Radio Interface on the
AC. The WTP Virtual Radio Interface provides a way to configure the
radio's parameters and query radio's traffic statistics, and reuse
wireless binding modules defined by other SDOs. The interface MUST
be modeled as an ifEntry, and ifEntry objects such as ifIndex,
ifDescr, ifName, and ifAlias are to be used as per [RFC2863].
Also, as an ifIndex [RFC2863] is used as a common index for
corresponding interfaces in the CAPWAP-BASE-MIB and specific wireless
technologies MIB modules, the AC MUST have a mechanism that preserves
the values of the ifIndexes in the ifTable at AC reboot.
Shi, et al. Informational [Page 9]RFC 5833 CAPWAP Protocol Base MIB May 2010
7.3. Relationship to ENTITY-MIB Module
The ENTITY-MIB module [RFC4133] meets the need for a standardized way
of representing a single agent that supports multiple instances of
one MIB. It could express a certain relationship between multiple
entities and provide entity properties for each entity.
In a centralized WLAN architecture, the SNMP agent runs on the AC and
is not required on the WTP. With the ENTITY-MIB module on the AC, it
could keep entity information such as firmware revision and software
revision of the AC and WTPs. From the ENTITY-MIB module's
perspective, the overall physical entity (AC) is a 'compound' of
multiple physical entities (that is, the WTPs connected to AC), and
all entities are each identified by a physical index. The
capwapBaseWtpTable of the CAPWAP-BASE-MIB module uses the
capwapBaseWtpPhyIndex object to store the mappings of WTP object
between CAPWAP-BASE-MIB and ENTITY-MIB modules.
By querying both the CAPWAP-BASE-MIB and ENTITY-MIB modules,
operators could query the status and properties of the AC and WTPs.
For example, they could get a WTP's current status through the
CAPWAP-BASE-MIB module, and a WTP's software revision information
through the ENTITY-MIB module. The CAPWAP-BASE-MIB module does not
duplicate those objects defined in the ENTITY-MIB module.
7.4. Relationship to Wireless Binding MIB Modules
The wireless binding MIB module of a wireless technology (such as
[IEEE.802-11.2007]) is required to be supported on the AC. The
CAPWAP-BASE-MIB module is able to support any wireless binding.
Through the ifIndexes of WTP Virtual Radio Interfaces, it provides a
consistent and abstract way of reusing MIB objects in the wireless
binding MIB modules. The CAPWAP-BASE-MIB module does not duplicate
those objects defined in the wireless binding MIB modules.
7.5. MIB Modules Required for IMPORTS
The following MIB module IMPORTS objects from SYSAPPL-MIB [RFC2287],
SNMPv2-SMI [RFC2578], SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580],
IF-MIB [RFC2863], SNMP-FRAMEWORK-MIB [RFC3411], INET-ADDRESS-MIB
[RFC4001], and ENTITY-MIB [RFC4133].
8. Example of CAPWAP-BASE-MIB Module Usage
Below, the IEEE 802.11 binding is used as an example of how the MIB
modules operate.
1) Create a WTP profile.
Shi, et al. Informational [Page 10]
RFC 5833 CAPWAP Protocol Base MIB May 2010
Suppose the WTP's Base MAC address is '00:01:01:01:01:00'. Create
the WTP profile as follows:
In capwapBaseWtpProfileTable
{
capwapBaseWtpProfileId = 1,
capwapBaseWtpProfileName = 'WTP Profile 123456',
capwapBaseWtpProfileWtpMacAddress = '00:01:01:01:01:00',
capwapBaseWtpProfileWtpModelNumber = 'WTP123',
capwapBaseWtpProfileWtpName = 'WTP 123456',
capwapBaseWtpProfileWtpLocation = 'office',
capwapBaseWtpProfileWtpStaticIpEnable = true(1),
capwapBaseWtpProfileWtpStaticIpType = ipv4(1),
capwapBaseWtpProfileWtpStaticIpAddress = '192.0.2.10',
capwapBaseWtpProfileWtpNetmask = '255.255.255.0',
capwapBaseWtpProfileWtpGateway = '192.0.2.1',
capwapBaseWtpProfileWtpFallbackEnable = true(1),
capwapBaseWtpProfileWtpEchoInterval = 30,
capwapBaseWtpProfileWtpIdleTimeout = 300,
capwapBaseWtpProfileWtpMaxDiscoveryInterval = 20,
capwapBaseWtpProfileWtpReportInterval = 120,
capwapBaseWtpProfileWtpStatisticsTimer = 120,
capwapBaseWtpProfileWtpEcnSupport = limited(0)
}
Suppose the WTP with model number 'WTP123' has one PHY radio,
which is identified by ID 1. The creation of this WTP profile
triggers the AC to automatically create a WTP Virtual Radio
Interface and add a new row object to the
capwapBaseWirelessBindingTable without manual intervention.
Suppose the ifIndex of the WTP Virtual Radio Interface is 10. The
following information is stored in the
capwapBaseWirelessBindingTable.
In capwapBaseWirelessBindingTable
{
capwapBaseWtpProfileId = 1,
capwapBaseWirelessBindingRadioId = 1,
capwapBaseWirelessBindingVirtualRadioIfIndex = 10,
capwapBaseWirelessBindingType = dot11(2)
}
The WTP Virtual Radio Interfaces on the AC correspond to the PHY
radios on the WTP. The WTP Virtual Radio Interface is modeled by
ifTable [RFC2863].
Shi, et al. Informational [Page 11]RFC 5833 CAPWAP Protocol Base MIB May 2010
In ifTable
{
ifIndex = 10,
ifDescr = 'WTP Virtual Radio Interface',
ifType = 254,
ifMtu = 0,
ifSpeed = 0,
ifPhysAddress = '00:00:00:00:00:00',
ifAdminStatus = true(1),
ifOperStatus = false(0),
ifLastChange = 0,
ifInOctets = 0,
ifInUcastPkts = 0,
ifInDiscards = 0,
ifInErrors = 0,
ifInUnknownProtos = 0,
ifOutOctets = 0,
ifOutUcastPkts = 0,
ifOutDiscards = 0,
ifOutErrors = 0
}
2) Query the ifIndexes of WTP Virtual Radio Interfaces.
Before configuring PHY radios, the operator needs to get the
ifIndexes of WTP Virtual Radio Interfaces corresponding to the PHY
radios.
As capwapBaseWirelessBindingTable already stores the mappings
between PHY radios (Radio IDs) and the ifIndexes of WTP Virtual
Radio Interfaces, the operator can get the ifIndex information by
querying this table. Such a query operation SHOULD run from radio
ID 1 to radio ID 31 according to [RFC5415]), and stop when an
invalid ifIndex value (0) is returned.
This example uses capwapBaseWtpProfileId = 1 and
capwapBaseWirelessBindingRadioId = 1 as inputs to query the
capwapBaseWirelessBindingTable, and gets
capwapBaseWirelessBindingVirtualRadioIfIndex = 10. Then it uses
capwapBaseWtpProfileId = 1 and capwapBaseWirelessBindingRadioId =
2, and gets an invalid ifIndex value (0), so the query operation
ends. This method gets not only the ifIndexes of WTP Virtual
Radio Interfaces, but also the numbers of PHY radios. Besides
checking whether the ifIndex value is valid, the operator SHOULD
check whether the capwapBaseWirelessBindingType is the desired
binding type.
Shi, et al. Informational [Page 12]RFC 5833 CAPWAP Protocol Base MIB May 2010
3) Configure specific wireless binding parameters for a WTP Virtual
Radio Interface.
This configuration is made on the AC through a specific wireless
binding MIB module such as the IEEE 802.11 MIB module.
The following shows an example of configuring parameters for a WTP
Virtual Radio Interface with ifIndex 10 through the IEEE 802.11
dot11OperationTable [IEEE.802-11.2007].
In dot11OperationTable
{
ifIndex = 10,
dot11MACAddress = '00:00:00:00:00:00',
dot11RTSThreshold = 2347,
dot11ShortRetryLimit = 7,
dot11LongRetryLimit = 4,
dot11FragmentationThreshold = 256,
dot11MaxTransmitMSDULifetime = 512,
dot11MaxReceiveLifetime = 512,
dot11ManufacturerID = 'capwap',
dot11ProductID = 'capwap',
dot11CAPLimit = 2,
dot11HCCWmin = 0,
dot11HCCWmax = 0,
dot11HCCAIFSN = 1,
dot11ADDBAResponseTimeout = 1,
dot11ADDTSResponseTimeout = 1,
dot11ChannelUtilizationBeaconInterval = 50,
dot11ScheduleTimeout = 10,
dot11DLSResponseTimeout = 10,
dot11QAPMissingAckRetryLimit = 1,
dot11EDCAAveragingPeriod = 5
}
4) Get the current configuration status report from the WTP to the
AC.
According to [RFC5415], before a WTP that has joined the AC gets
configuration from the AC, it needs to report its current
configuration status by sending a configuration status request
message to the AC, which uses the message to update MIB objects on
the AC. For example, for IEEE 802.11 binding, the AC updates data
in the ifTable [RFC2863] and IEEE 802.11 MIB module, and so on,
according to the message. For ifIndex 10, its ifOperStatus in
ifTable is updated according to the current radio operational
status in the CAPWAP message.
Shi, et al. Informational [Page 13]RFC 5833 CAPWAP Protocol Base MIB May 2010
5) Query WTP and radio statistical data.
After WTPs start to run, the operator could query WTP and radio
statistical data through CAPWAP-BASE-MIB and the specific binding
MIB module on the AC. For example, through dot11CountersTable in
the IEEE 802.11 MIB module, the operator could query the counter
data of a radio using the ifIndex of the corresponding WTP Virtual
Radio Interface. With the capwapBaseWtpTable table in the CAPWAP-
BASE-MIB module, the operator could query the properties of
running WTPs.
6) Run MIB operations through a CAPWAP protocol wireless binding MIB
module.
For example, for the CAPWAP IEEE 802.11 binding protocol
[RFC5416], some MIB operations such as MAC mode configuration for
a WLAN depend on the CAPWAP Protocol Binding MIB for IEEE 802.11
[RFC5834]. For more information, refer to [RFC5834].
7) Query other properties of a WTP.
The Operator could query MIB objects in the ENTITY-MIB [RFC4133]
module by using the capwapBaseWtpPhyIndex in the
capwapBaseWtpTable of CAPWAP-BASE-MIB module. The properties of a
WTP such as software version, hardware version are available in
the ENTITY-MIB module.

As most MIB modules use the ifIndex to identify an interface
for configuration and statistical data (for example, the IEEE

reuse other wireless binding MIB modules through the WTP

10. Security Considerations
There are a number of management objects defined in this MIB module
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. The followings are the tables and objects and
their sensitivity/vulnerability:
- Unauthorized changes to the capwapBaseWtProfileTable and writable
objects under capwapBaseAcs group MAY disrupt allocation of
resources in the network. For example, a WTP's static IP address
could be changed by setting the
capwapBaseWtpProfileWtpStaticIpAddress object.
- Unauthorized changes to writable objects under the capwapBaseAc
group MAY disrupt allocation of resources in the network. For
example, an invalid value for the capwapBaseWtpSessionsLimit
object will increase the AC's traffic burden.
- Unauthorized changes to the capwapBaseMacAclTable MAY prevent
legal stations from being able to access the network, while
illegal stations are able to access it.
- Unauthorized changes to writable objects under the
capwapBaseParameters group MAY influence CAPWAP protocol behavior
and status. For example, an invalid value set for the
capwapBaseAcDataCheckTimer MAY influence the CAPWAP state machine.
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. The followings are the tables and objects and
their sensitivity/vulnerability:
- The capwapBaseDataChannelDTLSPolicyOptions and
capwapBaseControlChannelAuthenOptions under the capwapBaseAc group
expose the current security option for CAPWAP data and control
channels.
- The capwapBaseWtpTable exposes a WTP's important information like
tunnel mode, MAC type, and so on.
- The capwapBaseWtpEventsStatsTable exposes a WTP's failure
information.
Shi, et al. Informational [Page 69]RFC 5833 CAPWAP Protocol Base MIB May 2010
- The capwapBaseRadioEventsStatsTable exposes a radio's failure
information.
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, the 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.
11. IANA Considerations
11.1. IANA Considerations for CAPWAP-BASE-MIB Module
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER value recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
capwapBaseMIB { mib-2 196 }
11.2. IANA Considerations for ifType
IANA has assigned the following ifType:
Decimal Name Description
------- ------------ -------------------------------
254 capwapWtpVirtualRadio WTP Virtual Radio Interface
