What Are IP ACLs?

IP ACLs classify for Layers 3 and 4 on IPv4 or IPv6 traffic.
Each ACL is a set of up to ten rules applied to inbound traffic. Each rule

specifies whether the contents of a given field should be used to permit or

deny access to the network, and may apply to one or more of the following

fields within a packet:

• Destination IP with wildcard mask
• Destination L4 Port
• Every Packet
• IP DSCP
• IP Precedence
• IP TOS
• Protocol
• Source IP with wildcard mask
• Source L4 port
• Destination Layer 4 port

What Is the ACL Redirect Function?

The redirect function allows traffic that matches a permit rule to be

redirected to a specific physical port or LAG instead of processed on the

original port. The redirect function and mirror function are mutually

exclusive. In other words, you cannot configure a given ACL rule with mirror

and redirect attributes.

What Is the ACL Mirror Function?

ACL mirroring provides the ability to mirror traffic that matches a permit

rule to a specific physical port or LAG. Mirroring is similar to the redirect

function, except that in flow-based mirroring a copy of the permitted traffic is

delivered to the mirror interface while the packet itself is forwarded normally

through the device. You cannot configure a given ACL rule with both mirror

and redirect attributes.
