    From the Release notes mac ACL is non-functional, so I assume you will have some problems with VLAN ACLs. I find the list of non-functional features in the release notes "non complete", so IP / IPV6 ACL on VLAN may hit the same thing as MAC ACL when you use it.

    Could you provide more details on "vlan acl does not work properly"? It is possible that the issue is not in the simulator, but in the way you design and apply VACLs.

    VACLs are applied to a VLAN within the VLAN context. Inbound VACLs filter all traffic that arrives on a VLAN whether switched or routed. Outbound VACLs filter all traffic  that is forwarded out a VLAN, whether the source is within the same subnet (switched) or another subnet (routed). Because both inbound and outbound VACLs filter traffic that arrives on a VLAN and is switched out that VLAN, some of the traffic that they filter overlaps.
