Hi expert,

I have a weird problem. I'm trying to create port-channel to to all directly 4 switches, when I add the ports into port-channel suddenly there is an error like this.

01:50:14: %SW_MATM-4-MACFLAP_NOTIF: Host 0030.9432.a420 in vlan 15 is flapping between port Fa0/24 and port Fa0/23

Anyone can explain? What should I do? I tried many ways to creating the port-channel but the output is still same.

Thanks in advance.

Regards,
Moses
