I have a 3560 switch and many access points plus cisco 3900 router but I don`t have any firewall. I want to apply mac filtering in my network.
I tried MAC-ACL but it can`t be apply to out bound of switch interface. and only allow me to apply it to ingress interface. but I want to apply it the way, that switch don`t send unauthorised packet to router (interface outbound)
please help me, and suggest a way for mac filtering.

Greetings Samiullah Osman and thanks for posting an interesting question.
What is the goal of your filtering outbound traffic? Perhaps filtering inbound and stopping the traffic from traversing your network could work?
Here is a support doc that might help with the 3560 mac filtering, using VLAN maps

@anboom totally right,
you can use MAC-ACL and add it to VLAN map and then any frame bridge inside this VLAN will filter by MAC-ACL
