The value of tmnxBsxIsaAaGrpIngressResvCbs specifies the
percentage of the buffer pool reserved for high priority
traffic for all traffic ingressing from the ISA-AA MDA.
The value '-1' implies that the reserved CBS should be
computed as the sum of the CBS requested by the entities
using this pool.
This object was obsoleted in release 7.0 and
replaced with the TIMETRA-PORT-MIB::tmnxObjectAppResvCbs object
in the TIMETRA-PORT-MIB::tmnxQosPoolAppTable.
