268 Configuring Switching Information
Packets can be filtered on ingress or egress. If the filter rules match, then some actions can be taken,
including dropping the packet or disabling the port. For example, a network administrator defines an
ACL rule that says port number 20 can receive TCP packets. However, if a UDP packet is received the
packet is dropped.
ACLs are composed of access control entries (ACE), or rules, that consist of the filters that determine
traffic classifications. The total number of rules that can be defined for each ACL is 127.
Use the IP ACL Configuration page to add or remove IP-based ACLs.
