Open a TAC case.  My peer mentioned to me that two of his clients had the same issue and had the unit RMA'd.

Hi Alcides,

What version of IOS-XE you run on this 5760 ?

Below may indicate wrong regulatory domain AP connected & 5760 rejecting the registration of them

Check correct regulatory domain AP are in use. Refer this for detail

Hi Rasika,

 

This part of regulatory domain is about one new AP that we've bought that is on AIR-CAP3602I-C-K9. the issue that I'm facing is that I get my AP's restarting on regular basis. and I can't figure out the reason  why.

 

best regards,

Alcides

Check the uptime of the individual APs.  If they rebooted, then check the cabling.

Hi Leo,

 

I've 42 APs configured on my controller do I've to check each one? because all of them reboot time to time.

 

Best regards,

Alcides

Still doesn't answer the question about faulty cabling.  Check every AP that bounces.  If the AP reboots, then you need to determine why first.  Cable will always be your "usual suspect".  

Hi Leo,

 

I found that it happen because spanning-tree issue... I found this log on Switch Core 6509 when the AP's was unavailable 

 

008694: Nov  3 11:34:51 GMT: %SPANTREE-2-LOOPGUARD_BLOCK: Loop guard blocking port Port-channel4 on VLAN0401.

How can I prevent this?

 

My Port-channel is configured like This

 

interface Port-channel4
 description Link to WLC-01
 switchport
 switchport trunk native vlan 3
 switchport trunk allowed vlan 4,400-402,993
 switchport mode trunk
 logging event link-status
 spanning-tree portfast edge trunk
 spanning-tree bpduguard disable

 

 spanning-tree portfast edge trunk
 spanning-tree bpduguard disable

Please take these two lines OFF your configuration.

Hi Leo,

 

Thanks for your attention,

 

 

Even with that line off I can't get ride off the spanning-tree issue

Post the configuration of the interfaces Ten 3/5, Ten 3/13 and PO4.

 

Also post the output to the command "sh run | i loopguard".

 

I want to see if you've got "spanning-tree guard loop" enabled or not.  This is the command that's shutting down your ports.

Also post the output to the command "sh run | i loopguard".

#sh run | i loopguard
spanning-tree loopguard default

There you go.  There's the culprit.  Take the off the global command. 

Hi Leo,

 

thanks for your attention but after removing that command the problem get worst
