Hello

Could someone help me what an orphan packet is in this context?

We have a device connected to an SSID but unable to access anywhere. The WLC status for the device is "authenticated" but here is the debug output for this device. The device(Windows) is getting an IP of 10.1.1.100 which matches the IP in the orphan packet line below.

Hello @cisco-ninja,

 

I found another discussion with a similar issue. It looks like a solution was never accepted but you could contact the original poster and ask them if they ever solved it, by replying to that discussion and/or sending them a direct message on the Community:

https://community.cisco.com/t5/wireless/dhcp-dropping-packet-due-to-ongoing-mobility-handshake-exchange/td-p/2948428

 

I also found a bug through the Cisco Bug Search Tool which may be relevant:

https://bst.cisco.com/bugsearch/bug/CSCvy49428

 

I hope this helps!
