I have 2 switches trunked together in this lab scenario. The scenario instructs me to do fallback bridging for VLANs 999 and 1000. On SW 1 I configured an SVI for each vlan, and configured the fallback bridging. On the first switch, I now continually get the below output: Note, the switches are linked via po12 port-channel. My first thought is that this is absolutely normal because the VLANs are bridged, but I wanted to make sure. It definitely is an annoyance when trying to finish the rest of the lab (I always turn on "logging con deb" so I can see everything necessary in the lab)
6d16h: %SW_MATM-4-MACFLAP_NOTIF: Host 000b.46e2.6997 in bridge group 1 is flapping between port Po12 (Vl1000) and port Po12 (Vl999)
