1.3.6.1.4.1.9.9.525 |
| This MIB is intended to be implemented on all those
devices operating as Central controllers, that
terminate the Light Weight Access Point Protocol
tunnel from Cisco Light-weight LWAPP Access Points.
Network management stations learn the audio/video
traffic quality observed on WLANs through this MIB.
The relationship between CC and the LWAPP APs
can be depicted as follows:

The LWAPP tunnel exists between the controller and
the APs. The MNs communicate with the APs through
the protocol defined by the 802.11 standard.
LWAPP APs, upon bootup, discover and join one of the
controllers and the controller pushes the configuration,
that includes the WLAN parameters, to the LWAPP APs.
The APs then encapsulate all the 802.11 frames from
wireless clients inside LWAPP frames and forward
the LWAPP frames to the controller.
This MIB provides the information about the per-client
/per-AP packet latency, packet jitter, packet loss and
roaming time in the network which does affect quality
of audio/video traffic. These parameters are called
Traffic Stream Metrics. When TSM collection is enabled
on all 802.11a/802.11b interfaces, the metrics are
collected by controller from AP in every 90 seconds
window.
Information provided by this MIB can be used by the
NMS applications to present measurements of audio and
video traffic quality.
GLOSSARY
Access Point ( AP )
An entity that contains an 802.11 medium access
control ( MAC ) and physical layer ( PHY ) interface
and provides access to the distribution services via
the wireless medium for associated clients.
LWAPP APs encapsulate all the 802.11 frames in
LWAPP frames and sends it to the controller to which
it is logically connected.
Central Controller ( CC )
The central entity that terminates the LWAPP protocol
tunnel from the LWAPP APs. Throughout this MIB,
this entity is also referred to as 'controller'.
Light Weight Access Point Protocol ( LWAPP )
This is a generic protocol that defines the
communication between the Access Points and the
Central Controller.
Mobile Node ( MN )
A roaming 802.11 wireless device in a wireless
network associated with an access point.
Traffic Stream Metrics (TSM)
These are parameters like the per-client / per-AP
packet latency, packet jitter, packet loss and roaming
time in the network, which does affect quality of
audio/video traffic. These statistics are collected
to study and characterize the pattern of data
traffic and perform appropriate management tasks to
regulate the same for the smooth functioning of the
network.
Channel Utilization (CU)
The Channel Utilization is defined as the percentage of time,
the QAP sensed the medium was busy, as indicated by
either the physical or virtual carrier sense (CS) mechanism.
Picc
Picc is the time consumed by AP for receiving frames
not destined to itself on a particular Radio interface
from co-channel APs and Clients.
Pib
Pib is the time consumed by AP for receiving frames on
a particular Radio interface which are not correctly de-modulated.

1.3.6.1.4.1.9.9.525.1.2.2 |
| This table represents the statistics received by the
controller from the associated APs, on the uplink
traffic ( traffic from the 802.11 wireless client to
the AP ) observed on the dot11 interfaces of the
respective APs.
For example, suppose a client with address
12:3f:73:99:de:5b connects to the 802.11 radio
interface, 13:13:43:de:bb:ff of an AP at 18:30:00 hours.
Assuming that cLTsmDot11aConfig (or cLTsmDot11bConfig)
is set to 'true' for the respective type of interface,
every 90 seconds, AP sends the controller statistical
data for the client 12:3f:73:99:de:5b associated at the
interface 13:13:43:de:bb:ff.
So, after 3 minutes, i.e., 180 seconds, controller would
have received statistics for the particular client and
AP combination twice leading to two rows in this table
as follows.
1> Client: 12:3f:73:99:de:5b
Interface:13:13:43:de:bb:ff Time: 18:33:00
2> Client: 12:3f:73:99:de:5b
Interface:13:13:43:de:bb:ff Time: 18:31:30
Now assume that, at 18:33:00, the client moves and
associates with another AP associated to the same
controller, at the AP's 802.11 interface
14:14:43:de:dd:ee.
After 3 minutes, i.e., 180 seconds (say), controller
would have again received statistics from the AP, for
the particular client and new AP combination twice
leading to two new rows in this table.
At this point, this table will have entries with
following references :
1> Client: 12:3f:73:99:de:5b
Interface:14:14:43:de:dd:ee Time: 18:36:00
2> Client: 12:3f:73:99:de:5b
Interface:14:14:43:de:dd:ee Time: 18:34:30
3> Client: 12:3f:73:99:de:5b
Interface:13:13:43:de:bb:ff Time: 18:33:00
4> Client: 12:3f:73:99:de:5b
Interface:13:13:43:de:bb:ff Time: 18:31:30
The maximum number of entries in this table is
indicated by cLTsmDot11MaxTsmStatsEntries. When
the specified limit of entries is reached the oldest
entries will be removed to make room for new entries.
However, the controller may remove the entries if it
encounters memory shortage. |

1.3.6.1.4.1.9.9.525.1.2.3 |
| This table represents the statistics received by the
controller from the associated APs, on the downlink
traffic ( traffic from the AP to the 802.11 wireless
client ) observed on the dot11 interfaces of the
respective APs.
For example, suppose a client with address
12:3f:73:99:de:5b connects to the 802.11 radio
interface, 13:13:43:de:bb:ff of an AP at 18:30:00 hours.
Assuming that cLTsmDot11aConfig (or cLTsmDot11bConfig)
is set to 'true' for the respective type of interface,
every 90 seconds, the AP sends the controller
statistical data about the 12:3f:73:99:de:5b associated
at the interface 13:13:43:de:bb:ff.
So, after 3 minutes, i.e., 180 seconds, controller would
have received statistics from the AP for the particular
client and AP combination twice leading to two rows in
this table as follows.
1> Client: 12:3f:73:99:de:5b

2> Client: 12:3f:73:99:de:5b
Interface:13:13:43:de:bb:ff Time: 18:31:30
Now assume that, at 18:33:00, the client moves and
associates with another AP associated to the same
controller, at the AP's 802.11 interface
14:14:43:de:dd:ee.
After 3 minutes, i.e., 180 seconds (say), controller
would have again collected statistics for the particular
client and new AP combination twice leading to two new
rows in this table.
At this point, this table will have entries as
follows.
1> Client: 12:3f:73:99:de:5b
