Hi, vfabian
- Is the device able to ping it's gateway ? No
- Is the device able to ping another device in the same segment ? No
- Can the controller ping the device ? No
- What's the lease for that segment ? Either 8 or 24 hrs. I am trying to verify. Can you see the active lease in the DHCP server ? Yes, the server shows an active lease
- Have you done a wireshark capture on the device and see if the device is sending an ARP request ? Yes, it authenticates and gets a new IP address from the DHCP Server. They did this with a support engineer. Can you see the ARP entry in the uplink or core switch ? No the controller still so the old IP address of the client. It does not seem to update the active user information. So it drops the traffic from the client seeing the same MAC with the wrong IP
- Can you share the user-debug logs from the controller ?I do not have one.
- Does it happen with a particular set of devices or segment ? It seems fairly random on the users except for a few that seem it happen more often. Other than that it is windows laptops and it only happens in the employee SSID but they do have a remote site that it happens to also.
