Hi zafar,
To make sure that the Po1(etherchannel)and ports(etherchannel) of the connected switch are correctly configured.
Is there any servers/pcs configured by using lancard-teaming features?
Cheers

Hi Thot,
Po1 (Etherchannel) between two of our Dist./Core is working fine (using LACP)with other switches these are the MAC address of two (Linksys SRW2048)switches which are causing these errors
I have'nt configured any server with the teaming feature, these error does'nt appear when i shutdown the backup interface of the Access switches.

Hi Shiva,
I have already isolated the Wireless devices from these two switches, wireless devices are connected to other switches which are working fine.
