Device authenticated but dont get IP

Hi!

 

Could you help me please?

I would like to connect HLK-RM04 wireless module on the AP 105 (controller: Aruba3400)....

I created new SSID with WPA2-PSK.. when I try connecting its success but device dont get IP address.

If i try it with mobile or laptop its works. They got IP. 

I already tried mac authentication... problem is same, dont get ip....

 

Is it possible that device not supported?

 

Thank you in advance!

Re: Device authenticated but dont get IP

Nothing unusual.  Please try to reconnect the device and run the command again...

Re: Device authenticated but dont get IP

Do this:

 

config t
logging level debugging network subcat dhcp
logging level debugging network process dhcpd

Disconnect then connect your device.  When it fails, type :

 

Show log network 50

Re: Device authenticated but dont get IP

It looks like you have two DHCP servers that are answering:

 

Apr 11 19:26:17 :202546:  <DBUG> |dhcpdwrap| |dhcp| Datapath vlan24: OFFER 94:db:c9:e3:df:22 Transaction ID:0xc9e3df22 clientIP=192.168.14.100

Apr 11 19:26:17 :202546:  <DBUG> |dhcpdwrap| |dhcp| Datapath vlan24: OFFER 94:db:c9:e3:df:22 Transaction ID:0xc9e3df22 clientIP=192.168.14.95

 

Your client wants the .100 address:

Apr 11 19:26:24 :202536:  <DBUG> |dhcpdwrap| |dhcp| Datapath vlan24: REQUEST 94:db:c9:e3:df:22 Transaction ID:0xc9e3df22

reqIP=192.168.14.100 Options 3d:0194dbc9e3df22 36:c0a80ef9 37:0103

 

The DHCP server says ok:

Apr 11 19:26:24 :202544:  <DBUG> |dhcpdwrap| |dhcp| Datapath vlan24: ACK 94:db:c9:e3:df:22 Transaction ID:0xc9e3df22 clientIP=192.168.14.100

 

It looks like your client is not responding to the ACK.  I would try to disable one of your DHCP servers if you have two in your environment.
