Controller can't see an AP 61

We have one Aruba3400 controller (running 3.3.2.14)  at our main site with AP 61s at 6 other sites connecting back to it.  I'm trying to set up an AP 61 at a new site connected back to the main site over a static VPN connection.  I provisioned the AP at the main site and when I take it over to the remote site the controller doesn't detect it.  The 2 lights on the left of the controller are bright but the one on the right stays dim green.  The AP pulls an IP address and I can ping it from the network the controller is on.  I have the serial breakout cable to connect to the AP if needed.  This is not a remote AP, the site is on a static VPN.  Thanks in advance for any ideas.

What is the output of the command 

 

show datapath session table <ap-ip-address>

Re: Controller can't see an AP 61

If the AP tunnel connection to the controller is traversing a VPN, try reducing the MTU in the AP system profile. If that helps, you've got an MTU problem down that VPN! You might have to tune the setting.

 

ap system-profile "WHATEVER YOURS IS"

mtu 1400

Kudos appreciated, but I'm not hunting! (ACMX 104)

Thanks for the replies.

I can only get an apboot> prompt after hitting enter to stop autoboot.  Here is the output when it boots.  Is that SIGKILL something to note?  It just cycles like this:

Re: Controller can't see an AP 61

AP is unable to find its Master IP address and hence it reboots. 

Done. Master is 0.0.0.0

 

Which of the following methods does the AP use to find out the master controller? 

 

1. DHCP 

2. ADP

3. DNS  (by default it looks for "aruba-master")

Re: Controller can't see an AP 61

I'm not sure which method but I saw in another post on a similar topic that they said to put in the command aruba-master <ip-address> to point it at the controller.  I just can't get to a prompt that lets me have those commands.  I guess I could bring the AP back to a main site where it does get detected by the controller and then use the breakout cable to connect to it and set the aruba-master to the controller's IP address.  I'm just not sure of the syntax.

Re: Controller can't see an AP 61

Hello,

 

try this in case of dns:

 

apboot> setenv servername <Wireless LAN switch host name>

 

or this in case of direct ip:

 

apboot> setenv serverip <Wireless LAN switch IP address>

apboot> setenv master <Wireless LAN switch IP address>

 

apboot> save
apboot> boot

 

i think its:

 

apboot> printenv

 

to show the current configuration.

Re: Controller can't see an AP 61

It worked when I set the aruba master IP address.  Thanks to all of you for your help.
