Controller Based WLANs

How do I change the mode of an AP that is stuck in the initial role that was assigned by the WMS database?

Product and Software: This article applies to all Aruba controllers and ArubaOS 3.4.x.

The initial mode of the access point (AP) is stored in the WMS database: type (AP or AM), channel, and power level. If the database has no entry, the access point uses the last stored value. If the value in the WMS database sets the AP to be an air monitor (AM), the unit is stuck in this mode.

To correct the error, go into the Linux shell of the controller.

Use the following MySQL commands to display the error entry, correct the entry, and verify the updated entry. The MySQL command is shown in BLUE. The name of the AP is shown in RED.


1) Select the database from Linux mode:

mysql wms

 

2) Verify the WMS entry for the AP that is stuck in AM mode:

mysql> select * from sap_xg where ap_name = "80.9.5";

+---------+------------+---------------+-------------+----------------------+-------+----------+------+------+-------------+---------+-------------+---------+----------------+------+----------------+

| ap_name | floor_name | building_name | campus_name | fqln | fixed | phy_type | x | y | type | channel | power_level | ht_type | ht_sec_channel | memo | modified_time |

+---------+------------+---------------+-------------+----------------------+-------+----------+------+------+-------------+---------+-------------+---------+----------------+------+----------------+

| 80.9.5 | n/a | n/a | n/a | 80\.9\.5.n/a.n/a.n/a | false | 802.11a | 56 | 55 | air-monitor | 52 | 28 | none | 0 | NULL | 20091008075257 |

| 80.9.5 | n/a | n/a | n/a | 80\.9\.5.n/a.n/a.n/a | false | 802.11g | 56 | 55 | air-monitor | 6 | 28 | none | 0 | NULL | 20091008075257 |

+---------+------------+---------------+-------------+----------------------+-------+----------+------+------+-------------+---------+-------------+---------+----------------+------+----------------+

2 rows in set (0.00 sec)

 

3) Update the entry:

update sap_xg set type=NULL where ap_name='80.9.5';


4) Verify the change:

mysql> select * from sap_xg where ap_name = "80.9.5";

+---------+------------+---------------+-------------+----------------------+-------+----------+------+------+-------------+---------+-------------+---------+----------------+------+----------------+

| ap_name | floor_name | building_name | campus_name | fqln | fixed | phy_type | x | y | type | channel | power_level | ht_type | ht_sec_channel | memo | modified_time |

+---------+------------+---------------+-------------+----------------------+-------+----------+------+------+-------------+---------+-------------+---------+----------------+------+----------------+

| 80.9.5 | n/a | n/a | n/a | 80\.9\.5.n/a.n/a.n/a | false | 802.11a | 56 | 55 | NULL | 52 | 28 | none | 0 | NULL | 20091008075257 |

| 80.9.5 | n/a | n/a | n/a | 80\.9\.5.n/a.n/a.n/a | false | 802.11g | 56 | 55 | NULL | 6 | 28 | none | 0 | NULL | 20091008075257 |

+---------+------------+---------------+-------------+----------------------+-------+----------+------+------+-------------+---------+-------------+---------+----------------+------+----------------+
