配置方式 * Purpose: This slide describes the different ways students can access the Catalyst switch or Cisco router to create a new configuration file or alter an existing one. Emphasize: The network device can be configured from several locations. After you create the initial configuration, you can configure the ports or interfaces to enable configuration over virtual terminal ports (vty). Both the router and switch support Telnet access as a virtual terminal. The router by default supports virtual terminals 0 through 4. The router can be accessed for configuration purposes from the console port, the auxiliary port, and five VTY lines at the same time—up to seven people can configure the router at once. You should caution students about the above point and inform them that security should be strictly observed through password protection to avoid unauthorized access of the configuration files. Another component important to configuration in the network is a TFTP server. The TFTP server can be a UNIX or PC workstation that acts as a central depository for files. You can keep configuration files on the TFTP server and then download them to the device. You can also configure them from a network management station running network management software such as CWSI, CiscoWorks, or HP OpenView. Before you can access or change the configuration from a virtual terminal, TFTP server, or network management station, you must have the device configured to support IP traffic.
