Configuring static binding entries and dynamic binding function fails on a port.  

IP Source Guard is not supported on the port which has joined an aggregation group. Neither static 

binding entries nor dynamic binding function can be configured on the port which has joined an 

aggregation group. 

Remove the port from the aggregation group.
