- Describe the principle of network operation, and understand the usage and function of main network equipment. Select components according to network specifications, explain how data is transmitted in the network with OSI and TCP / IP models and related protocols, and describe common network applications (including web applications). Describes the use and basic operation of the protocol in OSI and TCP models. Describe the effects of network-based applications (IP audio and IP video), explain the network topology and determine the network path between two hosts across the network. Describes the structure of network and Internet communication, identifies and corrects the common network faults in layers 1, 2, 3 and 7, and distinguishes the functions and characteristics of Wan and LAN by using hierarchical model.
- Configure, inspect and repair VLAN and switch in switching communication environment. Select the appropriate media, cable, port and connection head to connect the switch with the host or other network equipment. Explain Ethernet technology and media access control method, explain the concept of network segmentation and basic traffic management, explain the concept of basic switching and the role of Cisco 350 801here. switch. Complete and verify the initial exchange configuration tasks, including basic programs for remote access control (including Ping, traceroute, telnet.SSH, ARP, ipconfig) and show & debug commands. Check the working status of network and switch, identify, specify and solve common switching network media problems, configuration problems, automatic negotiation and switching hardware failure. Describe advanced switching technologies (including VTP, RSTP, VLAN, PVSTP, 802.1Q), describe how VLANs create logically isolated networks and the necessity of routing between them. Configure, inspect and overhaul VLANs. Configure, inspect and repair the trunking of Cisco switch. Configure, inspect and repair inter VLAN routing. Configure, inspect and overhaul VTP. Configure, inspect and overhaul RSTP function. By explaining the output of show and debug commands in various cases, the working state of Cisco switching network is determined. Implement basic switch security policies (including: port security, aggregate access, management of VLANs other than vlan1, etc.)
- Realize IP address planning and IP services to meet network requirements in medium-sized branch office network. Describe the role and benefits of using private IP and public IP. Explain the role and advantages of DHCP and DNS. Configure, check and debug DHCP and DNS operations (including command line mode and SDM mode) on routers, implement static and dynamic IP address service for hosts in LAN environment, calculate and apply IP address in networks supporting VLSM (variable length subnet mask), plan to use VLSM and address summary. Determine the appropriate classless address planning to meet the requirements of different LAN / WAN address planning. This paper describes the technical requirements of implementing IPv6 in the coexistence with IPv4 network (including protocol release, dual stack mode and tunnel mode), describes IPv6 address, identifies and corrects common IP address and host configuration problems.
- Basic router operation and Cisco device routing configuration, check and error. The basic concept of routing modification (including IP packet forwarding, routing query), and Cisco router operation process (including router start process, post power on self-check, physical composition of router) are described. 350 401 encor training
