FIX:configure switch using CLI mode to set X vlans 
-X   is the number of desired Vlans.    
Procedure is:    
Connect on Switch CLI , go to global configuration mode (config)    
and ( We will use X = 64 ):    
switch (2810)  # max-vlans 64  
switch (2810)  # write memory  
switch (2810)  # reload    
Issue is resolved now and:    
Switch (2810)  # sh vlan    
Maximum vlans to support : 64
