| Description | 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. |
