Cisco CCNA Syllabus in 5 Days

35 Hours
A 5 day practical networking course designed to familiarise students with Cisco IOS (version 12). The course details the key commands used to configure and secure Cisco routers and switches, and covers the CCNA syllabus - including wired and wireless LAN access. Students will inter-connect networks by implementing static routes, distance-vector and link-state based dynamic routing protocols. The devices will be configured to route traffic across LAN/VLAN//WAN boundaries, by encapsulating datagrams across serial data links using various WAN protocols, such as HDLC, Frame Relay, ISDN and PPP (with CHAP authentication). VLAN encapsulation/tagging will be via IEEE802.1Q/P. Standard and Extended Access Control Lists will be configured and applied to router interfaces to filter traffic based on IP address and/or traffic type. Students will configure static and dynamic NAT to route between private and public networks and cover the theory of Virtual Private Networks (VPN's) Students will copy router configurations and IOS images to/from a TFTP Server. Privileged commands will be used to debug TCP/IP protocols to ensure proper operation of the routers. Students will also perform password recovery operations. The course is primarily aimed at IP v4 but does give an overview of IP v6 addressing and covers migration from an IP v4 to an IP v6 network. Other protocols and technologies (VPN's / Wireless) may be demonstrated if time permits. Course can be customised to precise requirements of customer. Audience: This course is suitable for anyone looking for a basic understanding of internetworking with Cisco devices and covers the CCNA syllabus. Course is approximately 50% practical
