IBM Tivoli and Cisco manual Setting the policy version

There are several parameters of interest:

￿The POLICY_VERSION parameter (Figure 5-6)establishes the version level of the policy. This field is simply a string value. The company version control process is strictly a manual one. During the network admission check, this version information is used to ensure that the client has an acceptable version of the compliance policy. (More on this in the next section.)

￿The MAX_DATA_AGE_SECS parameter (Figure 5-7)establishes the maximum data age for the posture cache data: When the workstation is challenged by the network for posture status it returns the data from its cache if the data is more recent than the maximum data age parameter. Otherwise the posture collectors are triggered, the posture cache is refreshed, and the posture data is returned to the network.
