Firmware version 18.03 to R10-9-0-E.biz

[Anonymous]

Installed R10-9-0-E on 90% of our devices and now we are unable to scan our network to pull device IP information for devices that are supported by a Windows DHCP server. Is there any reason to why this may have occured?

- I'm not sure why you may have run into that issue. Which network scanner are you using? What information is the scanner supposed to pull and what is it actually pulling since you've upgraded?

Thanks,

We currently use a free tool from Rradmin, Advanced IP scanner. This tool is quite helpful when dealing with DHCP issues or verify IP addresses that are in use. After the firmware upgrade, we are only receiving static ip address in the result field, nothing dhcp related. Which is a little strange.

- Have you tried to do a packet capture? It may be a good idea to get one with older code and one with newer code and compare. I would want to verify that the clients are receiving the request from the scanner and are responding.

I will try to obtain a pcap for you. This will take some time to acquire. I would be more willing to downgrade or identify a later version of software than to attempt capture packets. We have also ran into a lot locations having issues with DHCP and with our clients not being able to receive DHCP addresses. We need a solution now.

- At the time of this post, I would say to upgrade to R10.9.4 to get to the best maintenance release for your device.

Would you be able to post the DHCP debug from your AOS device of the failed attempt at obtaining an IP via DHCP?

Thanks,
