This attribute shows the aggregate SVC EIR (for excess traffic
transiting in the network through interrupting queue) assigned to
existing SVCs on the interface.
The value of currentAggregateSvcEirInterruptQ could be greater
than the provisionable value of
maximumAggregateSvcEirInterruptQ if the value of
maximumAggregateSvcEirInterruptQ has been changed during the
service of this FrUni or unlimitedAggregateEir is set to yes.
