VPN100 managed AP's rebooting almost every day

[Deleted User]

Hi all

I'm running two WAC6503D-S on a VPN100. They rebbot randomly, almost every day.

WAC6503D-S are on FW V5.40 Patch 2

VPN100 are on FW V4.35(ABFV.3) / 2020-02-26 11:27:47

Thank You for any help, Dany

Hi @Dany

Thanks for providing the diagnostic log of AP, we checked the issue was triggered by LLDP protocol, so we will enhance that soon.

Do you use any LLDP application/ scenario on the AP ? If not, could you disable LLDP function on the APs as below commands?

Router> configure terminal

Router(config)# no zon lldp server

Hi @Dany

Please help to collect the AP's diagnostic log by VPN100's GUI.

Go to MAINTENANCE > Diagnostics > Diagnostic > Collect on AP > Collect now.

Please download and provide the log file via private message to me.

We will analyze it to find out the root cause.

Thanks a lot.

Hello @Dany

Thanks for providing the diagnostic logs by private message, I checked that it is a bug caused by LLDP protocol.

So we release a date firmware to fix this issue, please download the latest AP date firmware by the VPN100 with the cloud server as the following steps.

 

1.Change the download path in VPN100 by CLI commands with using SSH or console method:

Router> configure terminal capwap firmware-update source 5.40(.2)-DF-2020-03-31

 

2.On the VPN100 GUI 

Wireless > AP Management > Firmware page, Click “Check” and “Apply”

3.AP starts to update the date firmware.

 

4.After the AP finish to upgrade the date firmware, change the download path to the official by CLI commands.

Router> configure terminal capwap firmware-update source official

Thanks!

Hi @Dany

Could you collect the AP's diagnostic log and provide it by private message?

Please provide the log of PoE switch which is connected to the APs as well.

Thanks!
