Catalyst 3500 block access to port by ip address

[joe.glynn]

Anyone know how to block access to a port on a Cisco Catalyst 3550 managed switch so only a range of IP Addresses can access the port and all other connections get discarded?

Thanks and regards

Joe

Port ACL might help you

If you want to control access based on MAC addresses consider port security
