The MIB's DESCRIPTION for cucsLsIssuesPropAcl is only the auto-generated stub 'Cisco UCS ls:Issues:propAcl managed object property', but the 'propAcl' property name together with its Unsigned64 type tell us this column, on the rolled-up configuration-issue summary for a service profile, covering network, server, storage, iSCSI, and vNIC checks, holds the propAcl as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The propAcl is the internal change-tracking bitmask for this issues object, used by UCS Manager to detect when any of its tracked issue fields changed, not something an admin reads directly for meaning. This value updates automatically whenever any of the issue categories on this profile change state.
