An arbitrary (system-assigned) index for each
instance of IPSLAs measure action. The index is unique
for each instance for a particular class in particular
policy-map. For example consider following configuration:
policy-map p1
class c1
measure type ip-sla group g1
measure type ip-sla group g2
class c2
measure type ip-sla group g3
In this case the cbQosMeasureIPSLACfgGroupIndex value
for first measure action instance under class c1 will be 1,
for second instance it will be 1, and so on. The value
for the index will start over again from 1 for class c2.
