Types of Access List. Restricting output of debug commands. Filtering traffic entering and existing an interface. Note: RFC contains assigned numbers of well-known ports On Cisco devices we have two main types of ACLs. These are Standard Access Control Lists and Extended Access Control Lists. Cisco Access Control Lists (ACLs) are used in nearly all product lines for several purposes, including filtering packets (data traffic) as it crosses from an inbound port to an outbound Introduction. For detailed command information and examples for ACL An ACL is a series of IOS commands that are used to filter packets based on information found in the packet header. This guide describes Access Control Lists (ACLs), and general ACL configuration information. As a traffic classification tool when used with QoS. Dial-on-demand routing (DDR) with ISDN.

The TCP refers to applications that There are two types of IP Access Lists The following IOS command permits http traffic from host to host address.
