802.11k list

[mwaibel]

Hello all,
I have a 9800-cl 17.9.3 in use and have a problem with the dot11k roaming list.
I am missing an access point in the roaming list.

Output neighbor scan of the AP "WZ-AP":
687d.b419.714f (BM-AP) 1 140 20 -57
687d.b419.06af (TE-AP) 1 116 20 -67
687d.b418.a20f (BD-AP) 1 132 20 -82

A connected client with the AP "WZ-AP" receives the following dot11k list:

Assisted Roaming Neighbor List
Nearby AP Statistics:
BD-AP (slot 1)
antenna 0: 3 s ago ........ -76 dBm
antenna 1: 3 s ago ........ -76 dBm
TE-AP (slot 1)
antenna 0: 2 s ago ........ -86 dBm
antenna 1: 2 s ago ........ -86 dBm
WZ-AP (slot 1)
antenna 0: 1 s ago ........ -63 dBm
antenna 1: 1 s ago ........ -63 dBm

Here, however, the AP BM-AP is now missing in the 11k list and the device never connects to the AP, because it is not on the list.

Does anyone have an idea?

Thank you

Hi

 This is probably not a problem. Unless when you move toward this AP the connection drops.

The assisted roaming feature is based on an intelligent and client optimized neighbor list. The 802.11k neighbor list is generated dynamically on-demand and is not maintained on the controller. Two clients on the same controller but different APs can have different neighbor lists delivered depending on their individual relationship with the surrounding APs.

By default, the neighbor list contains only neighbors in the same band with which the client is associated. However, the dual-list configuration allows 802.11k to return neighbors in both bands.

Clients send requests for neighbor lists only after they associate with the APs that advertise the Radio Management (RM) capability Information Element (IE) in the beacon. The neighbor list includes information about BSSID, channel, and operation details of the neighboring radios."
