■ To configure named ACLs, refer to “Configuring a Named ACL” on
page 10-54.
■ To configure extended, numbered ACLs, refer to “Configuring and
Assigning a Numbered, Extended ACL” on page 10-48.
A standard ACL uses only source IP addresses in its ACEs. This type of ACE
is useful when you need to:
■ Permit or deny traffic based on source IP address only.
■ Quickly control the IP traffic from a specific address, a group of
addresses, or a subnet. This allows you to isolate traffic problems
generated by a specific device, group of contiguous devices, or a
subnet threatening to degrade network performance. This gives you
an opportunity to troubleshoot without sacrificing performance for
users outside of the problem area.
You can identify each standard ACL with a number in the range of 1 - 99, or an
alphanumeric string of up to 64 characters. The CLI command process for
using an alphanumeric string to name an ACL differs from the command
process for a numeric name. For a description of how to name an ACL with
an alphanumeric character string, refer to
“Configuring a Named ACL” on page
10-54. To view the command differences, refer to table 10-1, “Comprehensive
Command Summary” on page 10-5.
Note For a summary of ACL commands, refer to table 10-1, “Comprehensive Com-
mand Summary”, on page 10-5.
