Cisco Prime 3.9 not discovering AP's on 9800-CL

meditinst — Tue, 28 Jun 2022 17:17:59 GMT

Hello,

We just installed a new 9800-CL controller and updated to prime 3.9 for support of it. Pime says AP Discovery is complete and Telemetry Status is a success but it has not found any of our AP's yet. We have 2702's and we have C9115AXI access points. Does anyone know how to get prime to see our access points?

Thanks,

Mike

Does the WLC is "managed" on cisco Prime?

Hi Flavio,

Yes it shows as managed and shows under the wireless controller device type as well.

Do you have any Firewall between Prime and Cat 9800, then you need to open some ports mentioned below document :

Ports Used

Communication between C9800 and Prime Infrastructure uses different ports.

All config and templates available in Prime Infra will be pushed via SNMP and CLI.This uses UDP port 161.
Operational data for C9800 WLC itself is obtained over SNMP. This uses UDP Port 162
AP and client operational data leverages streaming telemetry.
Prime Infrastructure to WLC: TCP port 830 - This is used by Prime Infra to push the telemetry configuration to 9800 devices (using netconf)
WLC to Prime Infrastructure: TCP port 20828 (for IOS-XE 16.10 and 16.11) or 20830 (for IOS-XE 16.12,17.x and later) -

Hi BB,

No there is no firewall between the two. Are there any commands you would like to see the output of?

Thanks,

Mike

It can be in managed state but with partial collection failure, check all the tabs and see if you see partial collection failure for that controller anywhere, additionally to View details about the information that was collected from the device hover your mouse over the Inventory Collection Status field and clicking the icon that appears, let us know if You see any failure there.

hope this helps

Hello,

If I hold my mouse over the "i" icon it pops up a box that says

Collection Status Details

Collection Status: Collection completed successfully

I don't see any failures anywhere for it.

Thanks,

Mike

I did find an error that said, Catalyst 9800 Telemetry coral connection failure for device Please check the coral connection. After rebooting the WLC the AP's showed up for me.
