Using Access Control Lists (ACLs) in Your Network

ACLs allow the configuration of permit and denial of IPv4 and IPv6 packet forwarding based upon IP address, protocol, and port matching, depending upon the ACL type. The 7100-Series firmware support configuration of both standard and extended ACLs. Standard ACLs allow the packet source IP address to be configured, while extended ACLs allow both source and destination IP addresses, protocol and TCP or UDP port matching, as well as the optional specifying of a DSCP, ToS, or IP precedence value. ACLs are also used to match addresses or traffic by client applications such as route map (for policy-based routing and route redistribution), and IP Directed Broadcast.
