access 1 permit 192.168.168.254
access 1 deny 192.168.168.35
Then I apply it to the specific port:
access 1 in
But I can still ping IP address .35 from the machine on the port in question and from the computer with that IP address, I can ping back. This is very frustrating. Can someone tell me what I am doing wrong?
If they are on the same subnet and switch then it's probably never even hitting the processor so the ACL will not work . ACL's are meant for traffic generally going off the subnet . If you are just trying to ping a computer on the same subnet the switch will just look in the mac table and switch it and it doesn't bother with the processor . Someone correct me if i am wrong . I am not real familiar with the 3550 so maybe i am missing something .
