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
Figure 3-8, 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 configure it.
Figure 3-8 Network diagram for Telnetting to another switch from the current switch
1) Perform Telnet-related configuration on the switch operating as the Telnet server. Refer to
Telnet Configuration with Authentication Mode Being None, Telnet Configuration with
Authentication Mode Being Password
, and Telnet Configuration with Authentication Mode
Being Scheme
for more.
2) Telnet to the switch operating as the Telnet client.
3) Execute the following command on the switch operating as the Telnet client:
<Sysname> telnet xxxx
Note that 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.
4) After successful login, the CLI prompt (such as <Sysname>) appears. If all the 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!”.
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 information about the commands.
