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. \ No newline at end of file -- cgit 1.2.3-korg
