Telnet Connection Establishment 61
two Ethernet ports belong to are of the same network segment, or the route
between the two VLAN interfaces is available.
As shown in Figure 15, 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.
Figure 15 Network diagram for Telnetting to another switch from the current switch
Step 1: Configure the user name and password for Telnet on the switch operating
as the Telnet server. Refer to section “Telnet Configuration with Authentication
Mode Being None” on page 49, section “Telnet Configuration with
Authentication Mode Being Password” on page 52, and section “Telnet
Configuration with Authentication Mode Being Scheme” on page 54 for more. By
default, Telnet users need to pass the password authentication to 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:
<SW4800G> telnet xxxx
Where xxxx is the IP address or the host name of the switch operating as the Telnet
server. 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
<SW4800G>) appears. 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!”.
Step 5: After successfully Telnetting to the 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
