Access Control Lists (ACLs) for the Series 5300xl Switches
Configuring and Assigning an ACL
Configuring and Assigning a Numbered, Standard ACL
This section describes how to configure numbered, standard ACLs.
■ To configure named ACLs, refer to “Configuring a Named ACL” on
page 9-44.
■ To configure extended, numbered ACLs, refer to “Configuring and
Assigning a Numbered, Extended ACL” on page 9-38.
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. 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 configure up to 255 standard ACL assignments, depending on how
many extended ACL assignments are already configured. (The switch allows
a maximum of 255 unique ACL identities; standard and extended combined.)
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 naming an ACL with an
alphanumeric character string, refer to
“Configuring a Named ACL” on page
9-44. To view the command differences, refer to table 9-1, “Comprehensive
Command Summary” on page 9-4.
Note For a summary of ACL commands, refer to table 9-1, “Comprehensive Com-
mand Summary”, on page 9-4.
