5.29 ACL Configuration (Access Control Lists)
ACL (Access Control List) is a table which defines filtration rules for incoming traffic based on IP and
MAC addresses sent in packets of protocols and TCP/UPD ports.
ACLs for IPv6, IPv4 and MAC addresses should have different names.
IPv6 and IPv4 lists can be used simultaneously in one physical interface. A MAC-based ACL
can not be used at the same time with IPv6 and IPv4 lists. Two lists of the same time can
not be used for the same interface.
The global configuration mode has commands which can be used to create and modify ACLs.
Global Configuration Mode Commands
Command line in the global configuration mode appears as follows:
console (config)#
