Launch Telnet
Step 5: Enter the password when the Telnet window displays “Login authentication” and
prompts for login password. The CLI prompt (such as <H3C>) appears if the password
is correct. If all VTY user interfaces of the switch are in use, you will fail to establish the
connection and receive the message that says “All user interfaces are used, please try
later!”. A H3C series Ethernet switch can accommodate up to five Telnet connections at
same time.
Step 6: After successfully Telnetting to a switch, you can configure the switch or display
the information about the switch by executing corresponding commands. You can also
type ? at any time for help. Refer to the following chapters for the information about the
commands.
Note:
z
A Telnet connection will be terminated if you delete or modify the IP address of the
VLAN interface in the Telnet session.

By default, commands of level 0 are available to Telnet users authenticated by
password. Refer to the System Maintenance and Debugging module for information
about command hierarchy.
3.5.2 Telnetting to Another Switch from the Current Switch
You can Telnet to another switch from the current switch. In this case, the current switch
operates as the client, and the other operates as the server. If the interconnected
Ethernet ports of the two switches are in the same LAN segment, make sure the IP
addresses of the two management VLAN interfaces to which the two Ethernet ports
belong to are of the same network segment, or the route between the two VLAN
interfaces is available.
As shown in
, after Telnetting to a switch (labeled as Telnet client), you can
Telnet to another switch (labeled as Telnet server) by executing the
telnet
command
and then to configure the later.
