6.3.1.1- 4.0.0.1 version DHCP Timeouts + Access points rebooting?

Hi All,


It seems since upgrading to the latest Firmware 6.3.1.1- 4.0.0.1 i am seeing a lot of DHCP Timeouts, at least 35-40 alerts?

 

Also some access points are rebooting?

 

Is there a resolve for this?

 

Thanks

Hi,

Did you find the reboot reason for the APs? They are in the 'show tech-support' or the 'show version' output.

Regarding the DHCP time out, are there clients that are not able to get an IP address? In your config, is the DHCP server external or internal to the VC?

Thanks,

Yan

Re: 6.3.1.1- 4.0.0.1 version DHCP Timeouts + Access points rebooting?

Hi Yan,

 

Thanks for your reply, There are quite a number of clients who cannot get an IP Address at least 15-20, the DHCP Server is Internal to the VC, i have it set so the Virtual Controller assigns the IP Address.

 

It seems only a couple of the AP's are rebooting not all in a cluster of 12, the Radio lights are solid red and then keep rebooting.

 

Is there anything i can check? at the moment i have temporaily reverted back to using firmware version 6.2.1.0-3.4.0.1_39461 which seems to resolve the DHCP problem?

 

 

Thanks

Hi Nisha,

Could you send us the output of 'show tech-support' from your VC running 3.4.0.1? We would first like to understand your network topology and configuration. Are all the APs connected together using a single switch?

Thanks,

Yan

Yes all AP's are connected to a single Netgear POE. Below is the output.

Re: 6.3.1.1- 4.0.0.1 version DHCP Timeouts + Access points rebooting?

Hi,

This does not appear to be a complete output? If it is difficult to grab the whole output, which I know is very large, you could also try just grabbing the 'show run' output.

Thanks,

Yan

Re: 6.3.1.1- 4.0.0.1 version DHCP Timeouts + Access points rebooting?

Are the clients currently getting addresses in the 172.31.98.0 subnet? Could this subnet be in use by the wired network somehow?

Before you upgraded, do you remember which subnet the clients were getting their IPs from?

Re: 6.3.1.1- 4.0.0.1 version DHCP Timeouts + Access points rebooting?

They are getting an ip in the 172.31.98.0 range, but this is seperate from the admin network and is not in use anywhere else.

before i ugraded the firmware the clients were still getting the same IP address in that range.

Re: 6.3.1.1- 4.0.0.1 version DHCP Timeouts + Access points rebooting?

Thank you for the update.

Given that information, I think it is best for us to focus on the AP rebooting issue first, and then look at the DHCP time out issue.

Do the rebooting APs reboot in a loop, and thus preventing any chance of opening a SSH CLI session to those APs?
