Options of dynamic binding:
1)   Disable: Cause this port to learn MAC address freely.
2)   Enable: Cause the port to bind MAC addresses until the specied number 
is reached. 
3)  --: This option is available only if the port is in a secure state, when this 
option is selected, the port state keeps unchanged. 
Port states:
1)  Free Port: The binding function is disabled, and the port can learn MAC 
address freely.
2)   Binding: The port is in binding state, and its bound MAC address number 
is still less than the max number.
3)  Secure Port: The port has already bound the max number of MAC 
address in dynamic binding mode, or it was set to secure port manually in 
"Port Parameter" page.

function cannot be congured now.
