I have been receiving below messages on 3 switches.
191: *Mar 7 02:30:48.326: %SW_MATM-4-MACFLAP_NOTIF: Host 148f.c639.e71a in vlan 100 is flapping between port Gi0/1 and port Gi0/2
I am attaching a diagram to give you more information about topology.
I have Vlan 100. You may say this used for two purposes.
1. A Router is connected to a Switchport in Vlan 100. This router provides the internet access to guest. The guests ( associated with AP) receive DHCP address from the address
2. At the same time, I have some workstation connected to a switchport in vlan 100 having static assigned address pointing to core switche HSRP IP as defaul gateway
Workstation static ip
VLAN configuration on Switch

standby 100 preempt

I need to know why am I receiving the above mac flapping messages Is there poor design in place.
Thanks in advance
