CCNA certification shows the ability to install, configure, operate and troubleshoot medium-sized routing and switching networks. Professionals who have obtained CCNA certification have the corresponding knowledge and skills, can establish connections with remote sites through wide area networks, eliminate basic security threats, and understand the requirements of wireless network access.

CCNA training includes (but is not limited to) the use of the following protocols: IP, EIGRP, serial line interface protocol, RIPv2, VLAN, Ethernet and access control list (ACL). CCNA 1-4 Cisco Certified Network Engineer (CCNA) is the first step of Cisco professional certification, with a minimum requirement of 280 class hours.

The focus of this course is to solve the network application problems in the fields of science, communication and social research. Students will learn how to install and configure Cisco switches and routers in multi-protocol networks of local area networks and wide area networks (LANs and WANs), provide first-class troubleshooting services, and improve network performance and security.

CCNA is aimed at high school students and above, including the following contents:

1, the design idea and principle of WAN.

2.OSI seven-layer model, the common operation of intelligent Ethernet switch or router.

3. Use Cisco software to configure the IP addresses of various routers and switch devices in the WAN environment.

4. Password recovery and IOS update of 4.Cisco routers and switches.

5. Connect Cisco switches and routers according to the given network design specifications.

6. Configure the routing protocols supported by the router, such as RIP, IGRP, EIGRP and OSPF.

7. Configure the switch to realize VLAN setting and interconnection among thousands of hosts.
