Why AP cannot get ip address from WLC or external DHCP server?

[wfqk]

Hi, I configure DHCP at Cisco switch 3560 as the below show some relative configuration. AP1140 is connected to the switch port. but AP cannot get ip address. From the AP console, we can see "%CAPWAP-3-DHCP_RENEW: Could not discover WLC using DHCP IP. Renewing DHCP IP" WLC is connected to the switch via trunk

Also, I tried configuring internal DHCP of WLC, but it still cannot work. Anyone can give some suggestion? Thank you

Switch#

Hi There.

Is your SVI 10 or interface vlan up?

you can check it using " show ip inter brief"

be sure that vlan in layer 2 exist.

Thanks for your reply

Yes SVI 10 is up via checking "show ip inter brie"

Well, your configuration on port 3 looks fine, if you can console to AP use this command:

"debug dhcp detail" and please share the output.

[wfqk]

yes, management interface is also in vlan10 

below is debug info:

[Daniel Ordóñez Flores]

Ok.

*Mar 1 00:13:26.698: DHCP: Scan: Renewal time larger than Rebind time

Be sure that only 3560 DHCP server is working and delete the line: lease infinite

ip dhcp pool Vlan_10
network 10.1.1.0 255.255.255.0
default-router 10.1.1.10
lease infinite

I see the offering message from DHCP Server but it looks some issues with timers. 

[wfqk]

after removing "lease infinite" the debug change a little, and "*Mar 1 00:13:26.698: DHCP: Scan: Renewal time larger than Rebind time" does not exist. but AP can not still join. the new debug is as follow:

[Daniel Ordóñez Flores]

Actually, I see the ACK packet from DHCP server operation and I see the AP got 10.1.1.43 ip address.

Now, If we already have an IP Address we need to use another command to check why is not join.

Please share the outputs of these commands:

On the AP:

show log

show capwap client rcb

debug capwap client detail

debug capwap client events/error 

On the WLC:

show msglogs

show traplogs  debug mac addr <AP Ethernet/Radio mac>

Which is the WLC ip address?

Post "show sysinfo" & "show interface" summary output from your WLC. It looks like WLC got multiple interfaces and AP discovery message is coming via those dynamic interfaces

To test it out, you can statically point your AP to WLC management IP address and it should work as a workaround.

LAP#capwap ap primary-base <WLC_Name> <WLC_Mgt_IP>

Thanks for your reply. please see below. and now PC can get ip address from DHCP server located in switch, but it looks like ap cannot get ip address

[Rasika Nayanajith · Accepted solution]

on you AP CLI, configure below

LAP#capwap ap primary-base Cisco_68:ca:03 10.1.1.9

and see if it go and register to WLC.

Since WLC is configured with US country code, I would verify AP regulatory domain matches (ie -A regulatory domain)

I added that command to the AP, but it still cannot work

Here is some "show ip interface bri " output:

AP-US-GA-GG044-F01-02-GA035#sh ip int bri
Interface IP-Address OK? Method Status Protocol
BVI1 10.1.1.12 YES DHCP up up
Dot11Radio0 unassigned NO unset up up
Dot11Radio0.18 unassigned YES unset up up
Dot11Radio1 unassigned NO unset up up
Dot11Radio1.18 unassigned YES unset up up
GigabitEthernet0 unassigned NO unset up up
GigabitEthernet0.1 unassigned YES unset up up

PC, AP and management interface are all in this vlan10. each of three device can ping each other. Strange, WLC cannot see AP

[Rasika Nayanajith]

Looks like AP got some sub-interfaces created (H-REAP config).Is that configuration done by you ? was this AP previously in use ?

If you are ok with erase AP config, try below

LAOP#debug capwap console cli
LAP#erase /all nvram:
LAP#reload

Once reload point it to WLC

AP#capwap ap primary-base Cisco_68:ca:03 10.1.1.9

I did that exactly based on your commands. but it still cannot work.
