| Description | 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
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 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
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. |
