ACL
This chapter describes how to configure the ACL feature on the WAP device. It
contains these topics:
• ACL Rule
• ACL Association
• ACL Status
ACL Rule
ACLs are a collection of permit and deny conditions, called rules, that provide
security by blocking unauthorized users and allowing authorized users to access
specific resources. ACLs can block any unwarranted attempts to reach network
resources.
The WAP device supports up to 32 IPv4, IPv6, and MAC ACL rules.
IPv4 and IPv6 ACLs
IP ACLs classify traffic for Layers 3 and 4.
Each ACL is a set of rules applied to traffic received by the WAP device. Each rule
specifies whether the contents of a given field should be used to permit or deny
access to the network. Rules can be based on various criteria and may apply to
one or more fields within a packet, such as the source or destination IP address,
the source or destination port, or the protocol carried in the packet.
NOTE There is an implicit deny at the end of every rule created. To avoid deny all, we
strongly recommend that you add a permit rule within the ACL to allow traffic.
