Aug 12, 2019
- Cisco Aironet 1850 Series Access Points
Known Affected Releases
Symptom: When a client roams from AP to AP, the client may be unable to receive unicast data for some time after the roam. A span of the roamed-from and roamed-to APs' switchports shows this: * upstream packets from the client are received by the roamed-to AP's switchport * however, downstream packets addressed to the cleint are transmitted by the wired network to the roamed-from AP At this time, examination of the CAM table on the APs' switch(es) shows that the client's MAC address entry still points to the roamed-from AP. After some time, the client's CAM table entry moves to the roamed-to AP, and downstream packets are now delivered to the client. Conditions: Seen with AP-COS APs, on a WLAN configured for FlexConnect local switching.
