Every thing works good, but when i execute the SHOW LOG command it shows the below log errors.  I've attached the whole configuration.

This seems a loop there. This could be due to a mis configuration since its just not one host is flapping but a bunch of them. 

Check what is connected to Po1 , Te 3/7 and Te4/7.

Ensure the port-channel 1 is configured correctly on the remote end too ?

Also check the config on remote side for Te3/7 and Te4/7
