20 CHAPTER 1: GETTING STARTEDFigure 6 Setting up the Configuration Environment through Telnet3 Run Telnet on the PC and enter the IP address of the VLAN connected to thenetwork port on the PC.Figure 7 Running Telnet4 The terminal displays Login authentication and prompts the user to enter thelogon password. After you enter the correct password, it displays the commandline prompt (such as <4500>). If the prompt All user interfaces are used,please try later! appears, too many users are connected to the Switchthrough Telnet. At most five Telnet users are allowed to log on to the SW4500Switch simultaneously.5 Use the corresponding commands to configure the Switch or to monitor therunning state. Enter ? to view online help. For details of specific commands, referto the following chapters.When configuring the Switch through Telnet, do not modify the IP address of theSwitch unnecessarily, for the modification might end the Telnet connection.By default, when a Telnet user passes the password authentication to log on to theSwitch, the access level for commands will be Level 0.Telneting a Switch Through Another SwitchAfter a user has logged into a Switch, it is possible to configure another Switchthrough the Switch through Telnet. The local Switch serves as Telnet client and thepeer Switch serves as the Telnet server. If the ports connecting these two Switchesare in the same local network, their IP addresses must be configured in the samenetwork segment. Otherwise, the two Switches must establish a route tocommunicate with each other.As shown in Figure 8, after you Telnet to a Switch, you can run the telnetcommand to log in to, and configure, another Switch.WorkstationWorkstationServ er PC ( for configuring the switchvia Telnet )Ethernet portEthernetWorkstationWorkstationServ er PC ( for configuring the switchvia Telnet )Ethernet portEthernet
