This attribute shows the aggregate SVC CIR (for traffic transiting in
the network through interrupting queue) assigned to existing SVCs
on the interface.
The value of currentAggregateSvcCirInterruptQ could be greater
than the provisionable value of
maximumAggregateSvcCirInterruptQ if the value of
maximumAggregateSvcCirInterruptQ has been changed during the
service of this FrUni.
