AP621 model does not return SNMP data via snmpwalk

[Elias_Morais_Pe]

hello @ckelly, @Christoph_S , @Christopher_Fra , @arichter 

We have 2 RFS6000 controllers and 35 devices of this model in our environment, but I can't retrieve SNMP data from them. We have another 12 devices of the AP7532 model, and I can easily get the information from them.

AP621

$ snmpwalk -v2c -c cti 172.19.0.91 (AP621)
Timeout: No Response from 172.19.0.91

AP7532

$ snmpwalk -v2c -c cti 172.19.0.100
iso.3.6.1.2.1.1.1.0 = STRING: "AP7532 Access Point, Version 5.8.6.9-003R MIB=01a"
iso.3.6.1.2.1.1.2.0 = OID: iso.3.6.1.4.1.388.50.1.1.40
iso.3.6.1.2.1.1.3.0 = Timeticks: (24005400) 2 days, 18:40:54.00
iso.3.6.1.2.1.1.4.0 = ""
iso.3.6.1.2.1.1.5.0 = STRING: "AP-A13-1314"

What is blocking the AP621 model? How can this be fixed?

EDIT:

I tried to follow the steps in the link below, but an error occurred. I think it's a bug.

Thank you in advance!!!

Is the management policy that is assigned to the 621 the same one that is applied to the 7532?

Yes, it's the same.
