2.8.6 Access control lists
Access control lists (ACLs) are filters that permit or deny traffic for security purposes. They
can also be used with QoS to classify and segment traffic to provide different levels of service
to different traffic types. Each filter defines the conditions that must match for inclusion in the
filter, and also the actions that are performed when a match is made.
IBM System Networking switches running IBM Networking OS V6.8 support the
following ACLs:
򐂰 Regular ACLs:
Up to 256 ACLs are supported for networks that use IPv4 addressing.
򐂰 IPv6 ACLs:
Up to 128 ACLs are supported for networks that use IPv6 addressing.
򐂰 VLAN Maps (VMaps):
Up to 128 VLAN Maps are supported for attaching filters to VLANs rather than ports.
