This read-only Gauge32 value reports the policy-resolution hierarchy level at which the settings for this vNIC Profile Instance instance were actually resolved. UCS policies can be inherited from a parent organization or overridden lower down, so this number tells an admin how far up the org tree UCS Manager had to look before it found the effective settings for this vNIC Profile Instance instance. For the instance of port-profile 'VM-Data-PP' pushed down onto the VIC adapter in blade chassis 1, slot 3, a policyLevel of 0 would mean the policy was defined directly at that instance's own organization, while a higher value would mean it inherited settings from an ancestor org further up the tree.
