Hi everyone,
in a FlexConnect branch environment we report on the switch (3650 or 2960) several times this log entry:
%SW_MATM-4-MACFLAP_NOTIF: Host xx in vlan yy is flapping between port Gi1/0/32 and port Gi1/0/33
I can understand that this will happen when the client is roaming (but then I don't understand why the entry is written only some time and not every time the client is roaming) , but I can not understand why the client MAC is also flapping between the client VLAN (Mapped via FlexConnect configuration) and the VLAN where the AP reside (Native VLAN) .
Did someone report similar behaviour?
I'm running 8.3.120 on a vWLC, Catalyst switch was updated to the latest recommended version.
Regards
Marco
