This object identifies the VLAN (1 to 4095) on
this radio interface.  The object value should
match the corresponding cwvlWlanVlanId in the
cwvlWlanVlanTable or cd11IfVlanSecurityVlanId
object in the cd11IfVlanSecurityTable.  When
the value is '0', the encryption keys are applied
to the non-VLAN configuration.

This object is a representative of the
corresponding 802.11 WEP Key Index used when
transmitting or receiving frames with this key.
SNMP table indexing conventions require table
index to be non-zero.  Therefore, this object has
to be one greater than the actual 802.11 WEP key
index.  A value of '1' for this object corresponds
to a value of '0' for the 802.11 WEP key index.

This object specifies the length in octets of
cd11IfVlanEncryptKeyValue.  Common values are 5 for
40-bit WEP key and 13 for 128-bit WEP key.  A value
of '0' means that the key is not set but the VLAN
is enabled.

This is the WEP secret key value.  The agent
always returns a zero-length string when this
object is read for security reason.

This object controls and reflects the status of
rows in this table.
When the row in 'active' state, the NMS can modify
both key length and value.  To delete a row, set this
object value to 'destroy'.

Only one of the 4 keys of a VLAN can be the transmit
key.  Setting any one of the 4 keys to 'true', the
agent will automatically change the value of
cd11IfVlanEncryptKeyTransmit of the other 3 keys to
'false' if they exist.

This is the VLAN ID (1-4095) to which the
parameters in each conceptual row shall be
applied.  If the value is '0', these paramters
apply to the non-VLAN configuration.

If the value is 'true', this VLAN sub-interface is
enabled on all trunk and hybrid ports.  If the value
is 'false', this VLAN is disabled on all ports.  For
platforms supporting NMS to create VLAN sub-interfaces,
setting this object to 'true' will create the
corresponding VLAN sub-interfaces on all ports and
'false' will remove the the corresponding VLAN.

This is the broadcast key rotation period.  If the
value is '0', there is no key rotation.

If it is 'true', a new key will be used every time
when the common set of encryption capability among
clients of this radio on this VLAN is changed.

If it is 'true', a new key will be used every time
when a client of the radio on this VLAN disassociates.

These are all the possible cipher type combinations
currently supported for data frame encryption from
different IEEE 802.11 radio interface implementations.
Some platform may support only a subset of the
combinations.  Agent will not honor invalid combinations
and may reset the cipher type to 'none'.
none        No encryption,
aesccm      WPA AES CCMP encryption,
ckip        Cisco Per packet key hashing,
cmic        Cisco MMH MIC,

This is used to create a new row, modify or
delete an existing VLAN encryption configuration
in this table.
Creation of rows must be done via 'createAndGo' and
cd11IfVlanSecurityVlanEnabled and
cd11IfVlanSecurityCiphers columns are mandatory.
This object will become 'active' if the NMS performs
a multivarbind set including this object and
successfully creates the encryption configuration.
Modification and deletion of rows can be done via
'createAndGo' and 'delete' respectively when this
object is `active'.  Any encryption configurations
of a VLAN should only be deleted when it is not
being used for any client association.

Mac address of the active IEEE 802.11 radio device
to be monitored by this hot standby monitoring radio.
The cd11IfPhyMacSpecification of the local and remote
radios must be the same in order for the monitoring to
happen.

The frequency, in seconds, the remote active radio
specified by cd11IfRemoteRadioMacAddr is polled
for its health.

The total time, in seconds, this standby monitoring
radio unit can tolerate the failure of polling
of the active radio unit.  After this duration, one
more failure of the polling will trigger this hot
standby monitoring radio to take over and become an
active radio.  It will then stop all monitoring
activity and set the instance of
cd11IfLocalRadioMonitorStatus indexed by the
failed radio cd11IfRemoteRadioMacAddr to 'active'.

NMS can only set this object to monitor(2).  In
the monitor(2) state, this local radio will monitor
the remote radio specified in the
cd11IfRemoteRadioMacAddr.
When the remote radio fails or goes down, this local
radio will takeover the functions and became active.
The agent will set the instance of
cd11IfLocalRadioMonitorStatus indexed by the
failed radio cd11IfRemoteRadioMacAddr to 'active'.
This local radio will not monitor any other radios
when it is active, therefore, all other instances of
cd11IfLocalRadioMonitorStatus indexed by the same
ifIndex but different cd11IfRemoteRadioMacAddr
will be set to 'inactive'.

This object is used for creating, modifying, and
deleting rows in this table.
Creation of rows must be done via 'createAndGo'.
This object will become 'active' if the NMS performs
a multivarbind set including this object.
Any object in a row can be modified any time when
the row is in the 'active' state via 'createAndGo'.
Removal of a row can be done via setting this
object to 'destroy'.

When the radio is not functioning as a client
station (i.e., cd11IfStationRole is not
'roleClient'), this is the list of AIDs which this
agent will assign to the clients associating with
it.  An AID is assigned if the corresponding MAC
address matches that of the client.  This table has
an expansion dependent relationship on the ifTable.
For each entry in this table, there exists at least
an entry in the ifTable of ifType ieee80211(71).

This table contains shared WEP keys for all IEEE
802.11 packets transmitted and received frames over
a VLAN identified by the cwvlWlanVlanId if both VLAN
and encryption are enabled (i.e., the
cwvlWlanEncryptionMode is wep(2) or aes(3)) on the
radio interface.
If WEP encryption is enabled for the transmitted
IEEE 802.11 frames, then the Default Shared WEP
key in the set is used to encrypt the transmitted
broadcast and multicast frames associated with
the cwvlWlanVlanId.  Key '1' in the set is the
default key.  If an individual session key is not
defined for the target station address, then the
Default Shared WEP key will also be used to encrypt
or decrypt unicast frames associated with the
cwvlWlanVlanId.

GLOSSARY
Access point
Transmitter/receiver (transceiver) device
that commonly connects and transports data
between a wireless network and a wired network.
Association
The service used to establish access point
or station mapping and enable STA invocation
of the distribution system services.
(Wireless clients attempt to connect to
access points.)
Basic Rate
A data rate that is mandatory for client
devices to support in order for them to achieve
successful association.
Basic Service Set
The IEEE 802.11 BSS of an AP comprises of the
stations directly associating with the AP.
Bridge
Device that connects two or more segments
and reduces traffic by analyzing the
destination address, filtering the frame,
and forwarding the frame to all connected
segments.
Bridge AP
It is an AP that functions as a transparent
bridge between 2 wired LAN segments.
Broadcast SSID
Clients can send out Broadcast SSID Probe
Requests to a nearby AP, and the AP will
broadcast its own SSID within its beacons
to response to the clients. Clients can use
this Broadcast SSID to associate and
communicate with the AP.
Cyclic Redundancy Check
CRC is an error detect mechanism that applies
to frame transmission.
Direct-Sequence Spread Spectrum
DSSS combines a data signal at the sending
station with a higher data rate bit sequence,
which many refer to as a chipping code (also
known as processing gain).  A high processing gain
increases the signals resistance to interference.
DSSS sends a specific string of bits for each data
bit sent.
ERP-CCK Modulation
This signal modulation technique is supported in
PHY implmenting IEEE 802.11b/g Protocol.
ERP-OFDM Modulation
This signal modulation technique is supported in
PHY implmenting IEEE 802.11g Protocol.
Extensible Authentication Protocol
EAP acts as the interface between a wireless
client and an authentication server, such as a
RADIUS server, to which the access point
communicates over the wired network.
Extended Rate PHY
This PHY implements the IEEE 802.11g Protocol.
Frequency-Hopping Spread Spectrum
In FHSS, a hopping code determines the frequencies
the radio will transmit and in which order.  To
properly receive the signal, the receiver must be
set to same hopping code and listen to the
incoming signal at the right time and correct
frequency.  The code pattern maintains a single
logical channel.
IEEE 802.11
Standard to encourage interoperability among
wireless networking equipment.
IEEE 802.11b
High-rate wireless LAN standard for wireless
data transfer at up to 11 Mbps.
IEEE P802.11g
Higher Speed Physical Layer (PHY) Extension to
IEEE 802.11b, will boost wireless LAN speed to 54
Mbps by using OFDM (orthogonal frequency division
multiplexing).  The IEEE 802.11g specification is
backward compatible with the widely deployed IEEE
802.11b standard.
Inter-Access-Point Protocol
The IEEE 802.11 standard does not define how
access points track moving users or how to
negotiate a handoff from one access point to the
next, a process referred to as roaming.  IAPP is
a Cisco proprietary protocol to support roaming.
However, IAPP does not address how the wireless
system tracks users moving from one subnet to
another.
Independent network
Network that provides peer-to-peer connectivity
without relying on a complete network
infrastructure.
Integrity Check Value
The WEP ICV shall be a 32-bit value containing
the 32-bit cyclic redundancy code designed for
verifying wireless data frame integrity.
Message Integrity Check
A MIC can, optionally, be added to WEP-encrypted
802.11 frames.  MIC prevents attacks on encrypted
packets.  MIC, implemented on both the access point
and all associated client devices, adds a few bytes
to each packet to make the packets tamper-proof.
Native VLAN ID
A switch port and/or AP can be configured with a
'native VLAN ID'.  Untagged or priority-tagged
frames are implicitly associated with the native
VLAN ID.  The default native VLAN ID is '1' if
VLAN tagging is enabled.  The native VLAN ID is '0'
or 'no VLAN ID' if VLAN tagging is not enabled.
Node
Device on a network; has its own unique network
address and name.
Non-Root Bridge
This wireless bridge does not connect to the main
wired LAN segment.  It connects to a remote wired
LAN segment and can associate with root bridges and
other non-root bridges that accept client
associations.  It also can accept associations from
other non-root bridges, repeater access points,
and client devices.
Physical Layer Convergence Procedure
In IEEE 802.11 wireless LANs, PLCP defines a method
of mapping the IEEE 802.11 MAC sublayer protocol
data units into a framing format suitable for
sending and receiving user data and management
information between two or more wireless stations
using the associated PMD system.
Physical Medium Dependent
In IEEE 802.11 wireless LANs, a PMD system, whose
function defines the characteristics of, and method
of transmitting and receiving data through, a
wireless medium between two or more wireless
stations each using the DSSS.
Preamble
The radio preamble are data at the head of a
packet that contains information access points
and client devices required by IEEE 802.11 when
sending and receiving packets.
Primary LAN
In an AP, if the destinations of inbound unicast
frames are unknown, the frames are sent toward
the primary LAN defined on the device.
Radio carrier
Radio waves that deliver energy to a remote
receiver; in other words, radio waves in a
wireless LAN environment.
Repeater
Device that connects multiple segments,
listening to each and regenerating the signal
on one to every other connected one; so that
the signal can travel further.
Repeater or Non-root Access Point
The repeater access point is not connected
to the wired LAN.  The Repeater is a wireless
LAN transceiver that transfers data between
a client and another access point, another
repeater, or between two bridges.  The repeater
is placed within radio range of an access point
connected to the wired LAN, another repeater, or
an non-root bridge to extend the range of the
infrastructure.
Radio Frequency
Radio wave and modulation process or operation.
Root Access Point
This access point connects clients to the main
wired LAN.
Root (Wireless) Bridge
This wireless bridge connects to the main wired
LAN.  It can communicate with non-root wireless
bridges, repeater access points, and client
devices but not with another wireless root
bridge.  Only one wireless bridge in a wireless
LAN can be set as the wireless root bridge.
Spread-spectrum
Wideband radio frequency technique that
consumes more bandwidth than the narrowband
alternative but produces a signal that is louder
and easier to detect.  There are two types of
spread-spectrum radio: frequency hopping and
direct sequence.
Radio Service Set ID
SSID is a unique identifier that APs and clients
use to identify with each other.  SSID is a simple
means of access control and is not for security.
The SSID can be any alphanumeric entry up to 32
characters.
Tag header
A 'tag header' is as defined in the IEEE 802.1Q
standard.  An 802.1Q tag header contains a 3-bit
priority field and a 12-bit VLAN ID field.
A 'priority tag' has a VLAN ID of 0, to indicate
'no VLAN ID'.  A 'VLAN tag' has a non-zero
VLAN ID.
Virtual LAN
VLAN defined in the IEEE 802.1Q VLAN standard
supports logically segmenting of LAN
infrastructure into different subnets or
workgroups so that packets are switched only
between ports within the same VLAN.
VLAN ID
Each VLAN is identified by a 12-bit 'VLAN ID'.
A VLAN ID of '0' is used to indicate
'no VLAN ID'.  Valid VLAN IDs range from '1' to
'4095'.  VLAN of ID '4095' is the default VLAN
for Cisco VoIP Phones.
Wired Equivalent Privacy
WEP is generally used to refer to 802.11
encryption.
