AP Registration ( AIR-CAP 3602E-E-K9 )

[huzaif]

I am trying to get setup with my WLC 5508 and I have run into the next set of challenge...

Software version : 7.6.130.0

FRI: 7.6.101.1

My first AP out of the box started up and received an ip add and was listed under Wireless > ALL APS status "Downloading"

It received some IOS updates rebooted and now it never registers under the area above....

At first I thought it was option 43 in DHCP but than how did it work the first time...

Anyways to eliminate DHCP I assigned static ip add and static controller address as well

capwap ap controller ip address 10.31.99.21
capwap ap ip address 10.31.99.149 255.255.255.0

Still no joy !

Do I need to configure the controller with some settings before the AP can successfully register and start broadcasting my test SSID ?

I have posted below the error log the DHCP ip log and than the STATIC ip log...

Any help will be much appreciated.

cheers

I read some text on-line which was conflicting but I tried it any ways and no joy.

Tried the AP switch port as Trunk - No joy ( it would not even get an ip add from DHCP )

Tried the AP switch port as Trunk + native vlan set to AP - No joy ( it would not even get an ip add from DHCP )

Set the port back to Access now it does get an ip address..

What should my hex settings be for this specific AP model I am a little confused reading this article :(

Would this be the correct value for WLC within DHCP for the above mentioned AP?

I need to deploy 1552i + 3602E in this project...

0xf1040A1F6315  ( with no "spaces" inserted into the ASCI section of Windows DHCP option 43)
10.31.99.21

The AP keeps flashing RED and green

cheers

Yes, that Option 43 hex value is correct.

Regarding switchport type, it has to be ACCESS mode.

I do not think that is the issue here, as AP send join request to that WLC & still fails. May be regulatory domain issue or time.

Pls provide these info

WLC : show sysinfo & show time output

AP : show version output

Thank you for your response I had already left for the day hence the delayed response.

Here are my findings.

1. You are correct the country was not set correctly and I kept ignoring the irritating message box but it was advising me to disable the radios and I thought it had changed clearly not.

So  I disabled the and re-enabled and now it is set to GB correctly

=====================================================================================================
(Cisco Controller) >show country co

Configured Country............................. US  - United States
Configured Country Codes
        US  - United States............................. 802.11a Indoor,Outdoor / 802.11b / 802.11g
=====================================================================================================
(Cisco Controller) >config 802.11a disable network

Disabling the 802.11a network may strand mesh APs. Are you sure you want to continue? (y/n)y

(Cisco Controller) >config 802.11b disable network

=====================================================================================================
(Cisco Controller) >show country co

Configured Country............................. US  - United States
Configured Country Codes
        US  - United States............................. 802.11a Indoor,Outdoor / 802.11b / 802.11g

(Cisco Controller) >config country GB

Changing country code could reset channel & RRM grouping configuration.
If running in RRM One-Time mode, reassign channels after this command.
Check customized APs for valid channel values after this command.
Are you sure you want to continue? (y/n) y

Configured Country............................. GB  - United Kingdom

=====================================================================================================
 

(Cisco Controller) >config 802.11b enable network

(Cisco Controller) >config 802.11a enable network

========================================

(Cisco Controller) >show country code

Configured Country............................. GB  - United Kingdom
Configured Country Codes
        GB  - United Kingdom............................ 802.11a Indoor,Outdoor / 802.11b / 802.11g

========================================

Now it the sysinfo is showing the correct configuration...

I than opened a new 3602E-E-K9 and started the process from scratch and it upgraded the IOS and rebooted and now it registers with the WLC correctly.

I also assigned a static ip address + renamed the host name to reflect the naming standard and it worked like a treat !!! 

No more reboots...

2. So I have three different models of AP so will that setting not cause problems in DHCP?

3. Is there a generic option 43 setting ? As the initial digit points to the type of AP model correct ?

 4. Timezone was all set correctly. Eventually it will point to a NTP server early next week.

Thank you for pushing me in the right direction.

cheers

Hi

Good to see you figured this issue quickly.

Regarding the other queries you have here is my feedback

2. So I have three different models of AP so will that setting not cause problems in DHCP?

Yes, DHCP option 43 does not cause any issues with different AP model. I believe you use a single DHCP pool for all different AP models without using any DHCP vendor class option (60). In that way every AP get the WLC information via DHCP & even AP in different L3 network, it will be able to find your WLC & register. DHCP Option 43 & DNS method are two most commonly configured option for WLC discovery.

3. Is there a generic option 43 setting ? As the initial digit points to the type of AP model correct 

Yes, typically option 43 you can configure without option 60-vendor class identifier. See this video you will find out (was in the link you already found)
