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.

@David Souri the Native vlan is Vlan 63 and Management vLAN is Vlan 63 as well.

@Sam Lujan yes am using the radius server to authenticate

Are you using a radius server to authenticate?

Hi Thabiso,

Thank you for that information.

Can you tell me what the Native and Management vLAN assignments are for the Network Policy?

Based on that Switch Configuration:

General Mode PVID: 63 | This is what Aerohive refers to as Native

General Mode Tagged VLANs: These should be User-Profile assosciated VLANs and the Aerohive Management VLAN.

Happy to assist,

I believe that the DHCP Scope is working fine, I have double checked this morning. Below is my config on the port that the AP is connected.

Port: Gi1/0/1

VLAN Membership Mode: General Mode

Access Mode VLAN: 1 (default)

General Mode PVID: 63

General Mode Ingress Filtering: Enabled

General Mode Acceptable Frame Type: Admit All

General Mode Dynamically Added VLANs:

General Mode Untagged VLANs: 63

General Mode Tagged VLANs: 340,350

General Mode Forbidden VLANs:

Trunking Mode Native VLAN: 1 (default)

Trunking Mode Native VLAN Tagging: Disabled

Trunking Mode VLANs Enabled: All

Private VLAN Host Association: none

Private VLAN Mapping:

Private VLAN Operational Bindings:

Default Priority: 0

Protected: Disabled

~ The User-Profile and VLAN were pushed to the client aswell.

Hi Thabiso,

I can agree with Bill, that the next place to look would be the Switch-Port that the AP is connected to, after confirming that the DHCP Scope is correct at the Server, and that all Ports between the DHCP Server and AP are allowing the correct vLAN Tags.

Additionally, If the User-Profile and vLAN assignment was created in Hivemanager, but an Update was not pushed to the APs, the clients may still be getting assigned default vLAN attributes.

Happy to help,
