Operation Manual – LoginH3C S5500-EI Series Ethernet Switches Chapter 3 Logging In Through Telnet3-17Note:z A Telnet connection will be terminated if you delete or modify the IP address of theVLAN interface in the Telnet session.z By default, commands of level 0 are available to Telnet users authenticated bypassword. Refer to the System Maintenance and Debugging module for informationabout 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 3-6, after Telnetting to a switch (labeled as Telnet client), you canTelnet to another switch (labeled as Telnet server) by executing the telnet commandand then to configure the later.Figure 3-6 Network diagram for Telnetting to another switch from the current switchStep 1: Configure the user name and password for Telnet on the switch operating as theTelnet server. Refer to section 3.2 "Telnet Configuration with Authentication ModeBeing None”, section 3.3 “Telnet Configuration with Authentication Mode BeingPassword”, and section 3.4 “Telnet Configuration with Authentication Mode BeingScheme” for more. By default, Telnet users need to pass the password authenticationto login.Step 2: Telnet to the switch operating as the Telnet client.Step 3: Execute the following command on the switch operating as the Telnet client: telnet xxxxWhere 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.Step 4: Enter the password. If the password is correct, the CLI prompt (such as )appears. If all VTY user interfaces of the switch are in use, you will fail to establish the
