3-19. ACL
The 065-7727S switch access control list (ACL) is probably the most
commonly used object in the IOS. It is used for packet filtering but also for selecting
types of traffic to be analyzed, forwarded, or influenced in some way.
The ACLs are divided into EtherTypes. IPv4, ARP protocol, MAC and VLAN
parameters etc. Here we will just go over the standard and extended access lists for
TCP/IP. As you create ACEs for ingress classification, you can assign a policy for
each port, the policy number is 1-8, however, each policy can be applied to any port.
This makes it very easy to determine what type of ACL policy you will be working
with.
Function name:
High-ACL List / Low-ACL List
Function description:
The switch ACL function support up to 128 High Access Control List (High-
ACL) and 256 Low Access Control List (Low-ACL List), using the shared
128 High ACEs and 256 Low ACEs for ingress classification. You can create
an ACE and assign this ACE for each port with <Any> or assign this ACE for a
policy or assign this ACE for a port. There are 7 priorities, each port can select
one of policy, then decides which of the following actions would take according
to the packet’s IPv4, EtherType, ARP Protocol, MAC Parameters and VLAN
parameters:
