I have created a network policy on the HiveManager NG cloud, but my clients are not getting DHCP addresses. I tried to do the VLAN Probe and it says my VLAN's are not available. Please help. I tried checking all layers. I can connect to the AP via ssh and can ping other networks from the AP, but my clients aint getting DHCP ips

Hi Thabiso,
Thank you,
Could you go to the CLI of the AP with a Terminal Client like Putty(Windows) or OpenSSH admin@ip-of-AP
HowTo: https://thehivecommunity.aerohive.com/s/article/How-to-Connect-to-an-AP-using-SSH
Please try this command:
int mgt0 dhcp-probe vlan-range 340 340
Then, this command as well:
int mgt0 dhcp-probe vlan-range 350 350
They Should Pass If all is tagged up-stream and DHCP is properly configured.
If Not, we can continue Triage:
So far, you've confirmed the Switch-Port that the AP is connecting to Tags correctly.
- Can you check the same for any UP-stream switch?
- Including the Switch-Port that the DHCP Server is connected to.
Are you using vLAN 340 or 350 for the User-Profiles, or both?
If so, then the DHCP Probe commands above should have passed but if they fail, We'll want to locate where the drop is.
Please perform a Client Monitor with the MAC Address of the client device that's failing. We will want to determine which part of the DHCP Handshake is failing, OR if the problem is Radio Association.

Hope this helps,

Good day, the clients obtained DHCP addresses from VLAN 63. I had to go through the entire switch config and found out that the ip helper statement was ommited. I think the configs were not saved and we had power outages. I can succesfully probe VLAN 340. Will be testing if client can get ip addresses.
Thanks for you help.

The DHCP and Radius servers are separate. I can ping both from the switch. Let me try to put profile on VLAN 63 and see if I will get something.

That would/should confirm that the issue be a configuration issue related to VLAN 340. And give you a starting point to troubleshooting. If clients can get an IP on VLAN 63 as well that is.
You state you can ping the radius server, did you mean the DHCP server? Or do both services run on the same server?

@Brian Powers I can ping the radius server from the switch, The AP is on the management VLAN which is VLAN 63. So u suggest I put the user profile on the same VLAN as the AP?
