Chapter 34 Configuring Network Security with ACLs
Configuring IPv4 ACLs
Creating Standard and Extended IPv4 ACLs
This section describes IP ACLs. An ACL is a sequential collection of permit and deny conditions. One
by one, the switch tests packets against the conditions in an access list. The first match determines
whether the switch accepts or rejects the packet. Because the switch stops testing after the first match,
the order of the conditions is critical. If no conditions match, the switch denies the packet.
The software supports these types of ACLs or access lists for IPv4:
• Standard IP access lists use source addresses for matching operations.
• Extended IP access lists use source and destination addresses for matching operations and optional
protocol-type information for finer granularity of control.
These sections describe access lists and how to create them:
• Access List Numbers, page 34-8
• ACL Logging, page 34-9
• Creating a Numbered Standard ACL, page 34-10
• Creating a Numbered Extended ACL, page 34-11
• Resequencing ACEs in an ACL, page 34-15
• Creating Named Standard and Extended ACLs, page 34-15
• Using Time Ranges with ACLs, page 34-17
• Including Comments in ACLs, page 34-19
Access List Numbers
The number you use to denote your ACL shows the type of access list that you are creating. Table 34-1
lists the access-list number and corresponding access list type and shows whether or not they are
supported in the switch. The switch supports IPv4 standard and extended access lists, numbers 1 to 199
and 1300 to 2699.
