pktcEScTapMediationContentId is a session identifier, from the intercept application's perspective, and a content identifier from the Mediation Device's perspective. The Mediation Device is responsible for making sure these are unique, although the SNMP RowStatus row creation process will help by not allowing it to create conflicting entries. Before creating a new entry, a value for this variable may be obtained by reading pktcEScTapMediationNewIndex to reduce the probability of a value collision.
