3-11Telnetting to another Switch from the Current SwitchYou can Telnet to another switch from the current switch. In this case, the current switch operatesas the client, and the other operates as the server. If the interconnected Ethernet ports of the twoswitches are in the same LAN segment, make sure the IP addresses of the two managementVLAN interfaces to which the two Ethernet ports belong to are of the same network segment, orthe route between the two VLAN interfaces is available.As shown in Figure 3-8, after Telnetting to a switch (labeled as Telnet client), you can Telnet toanother switch (labeled as Telnet server) by executing the telnet command and then configure it.Figure 3-8 Network diagram for Telnetting to another switch from the current switch1) Perform Telnet-related configuration on the switch operating as the Telnet server. Refer toTelnet Configuration with Authentication Mode Being None, Telnet Configuration withAuthentication Mode Being Password, and Telnet Configuration with Authentication ModeBeing Scheme for more.2) Telnet to the switch operating as the Telnet client.3) Execute the following command on the switch operating as the Telnet client: telnet xxxxNote that xxxx is the IP address or the host name of the switch operating as the Telnet server. Youcan use the ip host to assign a host name to a switch.4) After successful login, the CLI prompt (such as ) appears. If all the VTY userinterfaces of the switch are in use, you will fail to establish the connection and receive themessage that says “All user interfaces are used, please try later!”.5) After successfully Telnetting to the switch, you can configure the switch or display theinformation about the switch by executing corresponding commands. You can also type ? atany time for help. Refer to the following chapters for the information about the commands.
