Operation Manual – LoginH3C S7500 Series Ethernet Switches Chapter 3 Logging in through Telnet3-16Figure 3-6 Launch Telnet5) Enter the password when the Telnet window displays “Login authentication” andprompts for login password. The CLI prompt (such as ) appears if thepassword is correct. If all VTY user interfaces of the switch are in use, you will failto establish the connection and receive the message that says “All user interfacesare used, please try later!”. A H3C series Ethernet switch can accommodate up tofive Telnet connections at the same time.6) After successfully Telneting to a switch, you can configure the switch or display theinformation 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.Note: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 Command Hierarchy/Command View section in CommandLine Interface module for information about command hierarchy.3.5.2 Telneting to Another Switch from the Current SwitchYou can Telnet to another switch from the current switch. In this case, the current switchoperates as the Telnet client, and the other operates as the Telnet server. If theinterconnected Ethernet ports of the two switches are in the same LAN segment, makesure the IP addresses of the two management VLAN interfaces to which the twoEthernet ports belong to are of the same network segment, or the route between thetwo VLAN interfaces is available.As shown in Figure 3-7, after Telneting 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.
