Operation Manual – LoginH3C S5600 Series Ethernet Switches Chapter 3 Logging In Through Telnet3-16Note:z A Telnet connection is terminated if you delete or modify the IP address of the VLANinterface in the Telnet session.z By default, commands of level 0 are available to Telnet users authenticated bypassword. Refer to the CLI part for information about command hierarchy.3.5.2 Telnetting to another Switch from the Current SwitchYou can Telnet to another switch from the current switch. In this case, the current switchoperates as the client, and the other operates as the server. If the interconnectedEthernet ports of the two switches are in the same LAN segment, make sure the IPaddresses of the two management VLAN interfaces to which the two Ethernet portsbelong to are of the same network segment, or the route between the two VLANinterfaces is available.As shown in Figure 3-8, after Telnetting to a switch (labeled as Telnet client), you canTelnet to another switch (labeled as Telnet server) by executing the telnet commandand 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 to Telnet Configuration with Authentication Mode Being None, TelnetConfiguration with Authentication Mode Being Password, and TelnetConfiguration with Authentication Mode Being 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 Telnetserver. You can use the ip host to assign a host name to a switch.4) After successful login, the CLI prompt (such as ) appears. If all theVTY user interfaces of the switch are in use, you will fail to establish theconnection and receive the message that says “All user interfaces are used,please try later!”.5) After successfully Telnetting to the switch, you can configure the switch or displaythe information about the switch by executing corresponding commands. You canalso type ? at any time for help. Refer to the following chapters for the informationabout the commands.
