8.10(105.4) 8.10(204.123) 8.10(204.129) 8.10(204.131) ap-17.2.0.31

Description (partial)

Symptom:
An access point doesn't send Neighbor Discovery Packets (NDP) on all of its 5GHz channels.  As a result, some of its neighbor APs may not see this AP as a neighbor in 5 GHz.  Meanwhile, the AP transmits NDP on all 2.4GHz channels.

Conditions:
Seen on 2800/3800/1560 series APs; does not apply to any other models.
