LAN ACLs (VACLs) can provide access control for all packets that are bridged within a VLAN or that are routed into or out of a VLAN for VACL capture. Unlike Cisco IOS ACLs that are applied on routed packets only, VACLs apply to all packets and can be applied to any VLAN. VACLs are processed in the ACL TCAM hardware. VACLs ignore any Cisco IOS ACL fields that are not supported in hardware.
You can configure VACLs for IP and MAC-layer traffic.
If a VACL is configured for a packet type, and a packet of that type does not match the VACL, the default action is to deny the packet.
Packets can either enter the VLAN through a Layer 2 port or through a Layer 3 port after being routed. You can also use VACLs to filter traffic between devices in the same VLAN.

It has been said in the vidoe that VACLs will be applied in interface but is seen to be config mode with juat specifying the vlan, moreover cisco CCNP 300-115 Official Cert Guide tells you that the packets within a VLAN can be filtered, it cant be filtered from one VLAN to rhe other

At 8:40 I saw you have a MAC access list. I have been searching for an example of MAC access list applied on a VLAN access map. Cisco TAC has been unhelpful. Can you PLEASE make a lab like that? Or point out where you have already done so? Thank you sir in advance

+Samih Khan we can filter the complete subnet as well but in case if you want to deny other networks we an use ACL on SVI interface after inter vlan as well
