Hi all,
I need help, we are using Cisco catalyst 2960 switch for our location, in switch for security purpose we are using Mac access list and all devices of location getting the ip thru dhcp which is configure in switch, now I want block dhcp services for all non permit Mac that they can't get ips untill they are not added in Mac access list,
i have tried below commands but its is not working.............................
These are commands,
Mac access-list extended abc
Permit host 1111.1111.1111 any
Permit host 2222.2222.222 any
And then applied it on every interface of switch
Interface range gi0/1-24
Mac access group abc in
access-list extended DENY-DHCP
deny udp any any eq bootps
deny udp any any eq bootpc
ip access list
vlan access map XYZ 10
match mac address abc
action forward
vlan access mac XYZ 20
match ip address 101
action dorp
vlan filter xyz vlan 1
Thanks in advance...

802.1X is much more scalable

In this case we have to use Authentication server AAA/SACS, i just want to block DHCP services for the MAC who is not in the mac access list, so they cant get IP until they permit in mac access list.
