List Name Permit For Free

There are two types of IPv4 ACLs: Standard ACLs: These ACLs permit or deny packets based only on the source IPv4 address. Extended ACLs: These ACLs permit or deny packets based on the source IPv4 address and destination IPv4 address, protocol type, source and destination TCP or UDP ports, and more.

A numbered, standard ACL is identified by a number in the range of 1 - 99 and is created without having to leave the global config context. Note that the CLI command syntax for creating a named ACL differs from the command syntax for creating a numbered ACL.

A named access control list is a list of permissions that can be attached to an object. It is a list consisting of one or more subjects (users, user groups, or pseudo-users) and operations (delete, edit, read, or change permissions) that are either allowed or denied to those particular subjects.

The ACL-name parameter is the access list name. You can specify a string of up to 255 alphanumeric characters. You can use blanks in the ACL name if you enclose the name in quotation marks (for example, "ACL for Net1"). ACL names must be unique across all IPv4 and IPv6 ACLs.

Standard ACLs identify the destination IP addresses of OSPF routes and can be used in a route map for OSPF redistribution. Standard ACLs cannot be applied to interfaces to control traffic. Licensing Requirements for Standard ACLs.

A Standard Access List refers to a set of conditions that are used to filter or deny traffic based on the source IP address. The ACL is a series of statements that will either permit or deny an incoming packet based on certain criteria.

Access Control List Examples. The most common examples of Access Control List include web servers, DNS servers, and remote access or VPN systems. The internal router of a DMZ contains stricter ACLs to protect the internal network from more specific attacks.
