1-7An H3C switch provides multiple VTY user interfaces. At one time, only one user can telnet to a VTYuser interface. Because a remote terminal cannot select the VTY user interface through which it logs into the switch, it is recommended that you configure all VTY user interfaces with the same authenticationmethod. The following example is configured in this way.The number of VTY user interfaces provided by a H3C device varies by switch model. In this document,a switch providing five VTY user interfaces is used as an example, which means that the VTY userinterface number ranges from 0 to 4. If your switch provides a different number of VTY user interfaces,make sure that the VTY interface number you configure is within the actual range.Telnet login configuration example# Enter system view. system-view# Enable the telnet service.[H3C] telnet server enable# Create VLAN-interface 1.[H3C] interface vlan-interface 1# Assign an IP address to VLAN-interface 1 according to the IP network segment distribution and usagein the current network. 192.168.0.72 is used as an example.[H3C-Vlan-interface1] ip address 192.168.0.72 24[H3C-Vlan-interface1] quit# Enter the view of VTY user interfaces 0 through 4.[H3C] user-interface vty 0 4[H3C-ui-vty0-4]# Configure the authentication method for the VTY user interfaces as needed.Omitted.
