I have a Cisco 2950 which is running:
IOS (tm) C2950 Software (C2950-I6Q4L2-M), Version 12.1(20)EA1a, RELEASE SOFTWARE (fc1)
and I want to use an access list to restrict IP traffic flowing through this switch. I know that full access-list functionalitity is only supported through the enhanced image but I can still define access-lists I just can't seem to assign them to anything.
What I would really like is for traffic flowing into FastEthernet 0/24 to be restricted to 1 specific Ip address. Failing that, I'd like traffic flowing into the switch to be restricted to one specific IP or even MAC.
Am I missing something or do I really need an EI to do any of this?
