Mac flapping issue for daisy chaining o

[rohatashsingh33830]

Hi Guys,

We have the mac flapping issue in daisy chaining  for cisco access point 1572EAC.

*Feb 12 16:30:17.959: %SW_MATM-4-MACFLAP_NOTIF: Host c4f7.d539.8fd0 in vlan 153 is flapping between port Gi1/1 and port Gi1/26
*Feb 12 16:30:19.878: %SW_MATM-4-MACFLAP_NOTIF: Host 00ee.ab83.51f0 in vlan 153 is flapping between port Gi1/1 and port Gi1/26
*Feb 12 16:30:23.720: %SW_MATM-4-MACFLAP_NOTIF: Host c4f7.d551.4960 in vlan 153 is flapping between port Gi1/1 and port Gi1/26
*Feb 12 16:30:24.265: %SW_MATM-4-MACFLAP_NOTIF: Host c4f7.d5d6.7f80 in vlan 153 is flapping between port Gi1/2 and port Gi1/26
*Feb 12 16:30:25.810: %SW_MATM-4-MACFLAP_NOTIF: Host c4f7.d52d.70a1 in vlan 153 is flapping between port Gi1/2 and port Gi1/26
*Feb 12 16:30:25.810: %SW_MATM-4-MACFLAP_NOTIF: Host c4f7.d52d.70a0 in vlan 153 is flapping between port Gi1/2 and port Gi1/26
*Feb 12 16:30:25.918: %SW_MATM-4-MACFLAP_NOTIF: Host 00ee.ab83.51f0 in vlan 153 is flapping between port Gi1/1 and port Gi1/26
*Feb 12 16:30:26.963: %SW_MATM-4-MACFLAP_NOTIF: Host c4f7.d539.8fd0 in vlan 153 is flapping between port Gi1/1 and port Gi1/26

Note:-Gi1/1 and G11/2 are port which Access point is connected.
Gi1/26 is port for Uplink(P2P switch connnectivity)

[Rich R · Accepted solution]

The switch is simply telling you that those client MACs are moving between ports - because they are - presumably while roaming between different APs.

And your question is what exactly?

[rohatashsingh33830]

Hi

Due to this AP are fluctuation on wlc.

Ap joining time is ok but some time is appears and some time not.

We need to fix the issue.

I have attached the network diagram as well as the port configuration.

Switch log:-
