Corresponding classify tables and sessions -are not created until control access list is assigned to an interface. - -Classify tables and sessions are removed from VPP when ACL assignment is deleted. - -ACLs can be shared among interfaces, but each time, new instance of classify table chain would be created in VPP. - -ACLs that are assigned to an interface have to be unassigned before update/removal. - -==== Operational state -Operational read in terms of ietf-acl model is not supported (would require storing additional metadata in vpp). -As a consequence, configuration data initialization based on operational state is not possible. - -To check how ietf-acl model was translated to classify tables/session, low-level vpp-classfier model can be used. - -=== Restrictions - -VPP classfier works in form of offsets and masks of 16B units. -The offset always starts at the beginning of L2 Ethernet header -of input packet. Because IP header can have variable length, -source/destination port matching (L4 features of ietf-acl model) is not possible.
