AP's not getting DHCP IP address

[Daniel_Starosci]

Hello, Im seeing a weird issue hopefully someone can help with.

We are moving our rf-domains from a flat vlan for the AP's in the campus to setting each rf-domain to a different subnet for the AP's. The AP's will get an IP from the Cisco MDF switch in each building.

I do this on the AP side by giving the AP a new profile with the correct port and vlan config.

For example, the AP is statically assigned an address on vlan 5. The new model uses vlan 799 and subnet 10.162.11.0/24.

On the switch, I change the switchport vlan from 5 to 799. On the AP, I give it a new profile that uses 799 on ge1 and 799 on the vlan.

For some strange reason the AP will not pick up an IP address. I can plug my laptop into that switch and get an address right away.

Anything I should be check to figure this out?

Thanks

Are there any debug commands we can try on the AP to see what is going on with DHCP?

Yes, this is part of the profile below:

interface ge1
switchport mode access
switchport access vlan 799
interface ge2
interface fe1
interface fe2
interface fe3
interface fe4
interface vlan799
ip address dhcp
ip dhcp client request options all

Is your configuration similar to something below:

code:

profile  
..
interface ge1
 switchport mode access
 switchport access vlan 799
interface vlan799
 ip address dhcp
 ip dhcp client request options all
...

The switchport can either be trunk or access. The vlan should be clearly defined and configure to receive DHCP address.

Please let me know if this helps
