Overview/Description
Access control lists enable administrators to identify specific traffic which get special treatment. This course introduces the general concepts of ACL operation and how ACLs can use wildcard masking, as well as how to determine the wildcard mask for a range of IP subnets. The course distinguishes between different types of ACLs, with a focus on the configuration for standard numbered ACLs. Two scalability challenges for the Internet are the depletion of the registered IPv4 address space and scaling in routing. Cisco IOS NAT and PAT are mechanisms for conserving registered IP addresses in large networks, and they also simplify IP addressing tasks. The course illustrates how to establish a translation between an inside local and inside global address using DHCP clients, NAT, and PAT on Cisco router.

Target Audience
Interconnecting Cisco Network Devices Part 1 is essential for students preparing for the CCNA Routing and Switching or CCENT certifications. Students pursuing the CCNA Routing and Switching certification should complete parts 1 & 2 of the ICND learning path. Students pursuing the CCENT certification need only attend part 1 of the ICND curriculum. Anyone wishing to obtain Cisco Certified Network Associate (CCNA) 100-101 certification that validates the knowledge and skills required to successfully install, operate, and troubleshoot small to medium size enterprise branch network. Network administrators, network engineers, network managers, network designers, and project managers. Familiarity of navigating PC operating systems, the Internet, and basic IP addressing knowledge skills recommended.
