Hello all,
Working on wireless, CAPWAP is initiated, however AP cannot be joined or discovered by WLC..
using 3700 AP and 2504 WLC
Show run and outputs are attached. (for core, access sw, WLC and AP)
CAPWAP State: Join
Finding DTLS connection to delete for AP (192:1xx:xxx:xx/xxxxx)
Disconnecting DTLS Capwap-Ctrl session 0x17aa3ba8 for AP (192:1xx:xxx:xx/xxxxx)
CAPWAP State: Dtls tear down acDtlsPlumbControlPlaneKeys: lrad:192.1xx.xxx.xx(xxxxx) mwar:192.1xx.xxx.x(xxxx)
DTLS keys for Control Plane deleted successfully for AP 192.xxx.xxx.xx

C3560 Software (C3560-ADVIPSERVICESK9-M), Version 12.2(46)SE, RELEASE SOFTWARE (fc2)
3560 doesn't support TDR so you'll need to find alternative method of testing the cable.
Can you post the complete output to the switch command "sh interface <AP PORT>"?

Not a cable fault.

Power down the AP for about 5 seconds and power back up.

as you see above, it's going up and down in couple seconds...
I will power down the AP and power back up. brb

Can you change the cable?
07-17-2017 09:06 PM
believe it or not, it's up.
do you have clue why this is happening? or maybe i need to unplug and plug when i notice this?
My other question is...
Does AP needs to be online? or it's okay as long as they are broadcasting SSID?
because none of this equipment are connected to the internet
When I try with an app, it says Wi-Fi not connected. and leads to the page wit h"login error, the internet connection appears to be offline." i've attached.

Yes, I've seen this before. It's a known bug.
Does AP needs to be online? or it's okay as long as they are broadcasting SSID?
I do not understand the question.
07-18-2017 08:31 AM
Does AP needs to be connected to the internet?
Please take a look at the attachment, that is the outcome from an app.
I can't configure universal AP through an app.

as soon as unplugged and plugged in...

another question,
Im at the link you shared with me "
Does AP needs to be online? or it's okay as long as they are broadcasting SSID?
because none of this equipment are connected to the internet
07-17-2017 06:35 PM
i tried shut, no shut, power inline never and auto, swap different cables and others more.
Have any clue? i'm using
"C3560 Software (C3560-ADVIPSERVICESK9-M), Version 12.2(46)SE, RELEASE SOFTWARE (fc2)"
Thanks...

For a 3700 AP, what would be the CLI commands to show joined (or attempted) WLC state and what SSID the AP is broadcasting?
Ive tried the suggested 'debug capwap' commands but the syntax doesnt match a 3700

take a look at from_ap txt, it's from today
