These are the steps to use ACLs:
Step 1 Create an ACL by specifying an access list nu mb er or n ame an d ac cess co ndi ti ons .
Step 2 Apply the ACL to interfaces or terminal lines. You can also apply standard and extended IP ACLs to
VLAN maps.
The software supports these styles of ACLs or access lists for IP:
•Standard IP access lists use source addresses for matching operations.
•Extended IP access lists use source and destination addresses for matching operat ions and optional
protocol-type information for finer granularity of control.
These sections describe access lists and the steps for using them:

supported in the switch. The Catalyst 3550 switch supports IP standard and IP extended access lists,
numbers 1 to 199 and 1300 to 2699.
