Dear All,
I have a strange issue, I have the 2 UCS servers setup with CCM & unity Connection running on each server on PUB - SUB mode.
I'm getting following error message on the Switch where the UCS server Connects.
I'm unable to trace why we are getting this error message, There is no problem with accessing CCM or UC, also the Phone & Voice mail seem to working.
un 25 13:15:14.853: %SW_MATM-4-MACFLAP_NOTIF: Host 000c.2911.db00 in vlan 410 is flapping between port Gi1/0/34 and port Gi1/0/33

Has anybody expereinced such error before, Appreciate your help in tracing this error.
Thanks,
Oliver

Hello,
I believe you'll get better answer at:
my best guess is to check the LAN config on the UCS. It seems its trying to load balance the traffic in Active-Active rather than Active-Standby.

Oliver,
Did you configure the UCS servers or the LAN switch that the UCS servers are connected to, as an ethercannel (load balancing)? If you didn't configure the UCS servers with MIC teaming (load balancing), verify with the network administrator, that the switchports connected to the UCS servers, are not setup as an etherchannel. If the ports are setup as an etherchannel, then you will need to make the changes to the VMWare network vSwitch as seen below:
