Description: Interface operational status.  Valid values are
operable, inoperable, standby, and degradedService.
Indicates whether it is fully inoperable and 
unable to provide service to the user, or it is 
fully operable and available for use.

Valid values are operable, inoperable, standby, 
degradedService and the transitional states of
inoperableIsInProgress and inoperableOosInProgress.
Depending on the V52 configuration, the transition
between inService and outOfService can take quite
some time for an interface group. The transitional
states give operator a more accurate indication of
a V52 IG's behavior.
