Access Control Lists (ACLs)
Configuring and Assigning an ACL
Options for Permit/Deny Policies
The permit or deny policy for IP traffic you want to filter can be based on
source IP address alone, or on source IP address plus other IP factors.
Standard ACL: Uses only a packet's source IP address as a criterion
for permitting or denying the packet. For a standard ACL ID, use either
a unique numeric string in the range of 1-99 or a unique name string
of up to 64 alphanumeric characters.
Extended ACL: Offers the following criteria as options for permit-
ting or denying a packet:
source IP address
destination IP address
IP protocol options:
Any IP traffic
Any IP traffic of a specific protocol type (0-255)
Any TCP traffic (only) for a specific TCP port or range of ports,
including optional control of connection traffic based on whether
the initial request should be allowed
Any UDP traffic (only) or UDP traffic for a specific UDP port
Any ICMP traffic (only) or ICMP traffic of a specific type and code
Any IGMP traffic (only) or IGMP traffic of a specific type
Any of the above with specific precedence and/or ToS settings
For an extended ACL ID, use either a unique number in the range of 100-
199 or a unique name string of up to 64 alphanumeric characters.
Carefully plan ACL applications before configuring specific ACLs. For more
on this topic, refer to “Planning an ACL Application” on page 10-30.
ACL Configuration Structure
After you enter an ACL command, you may want to inspect the resulting
configuration. This is especially true where you are entering multiple ACEs
into an ACL. Also, it is helpful to understand the configuration structure when
using later sections in this chapter.
The basic ACL structure includes four elements:
1. ACL identity and type: This identifies the ACL as standard or extended and
shows the ACL name or number.
2. Optional remark entries.
