def _get_if_state(self):
return self.__if_state<EOL>
Getter method for if_state, mapped from YANG variable /brocade_interface_ext_rpc/get_ip_interface/output/interface/if_state (enumeration)

    YANG Description: This indicates the current operational state
of this interface. The 'testing' state 
indicates that no operational packets can be
passed. If 'shutdown' leaf of corresponding 
interface instance of brocade-interface module
is set, then 'if-state' should be 'down'. 
If 'shutdown' is changed deleted, then 
'if-state' should change to 'up' if the 
interface is ready to transmit and receive 
network traffic; it should remain in the 'down'
state if and only if there is a fault that 
prevents it from going to the 'up' state.
