By default, commands of level 0 are available to Telnet users authenticated by
password. Refer to "Command Level/Command View" on page 19 for information
about command hierarchy.
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 14, after Telneting 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.

1 Perform Telnet-related configuration on the switch operating as the Telnet server.
Refer to "Telnet Configuration with Authentication Mode Being None" on page
52, "Telnet Configuration with Authentication Mode Being Password" on page
55, and "Telnet Configuration with Authentication Mode Being Scheme" on page
58 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:
<SW7750> 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.
4 Enter the password. If the password is correct, the CLI prompt (such as
<SW7750>) 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!".
5 Step 5: After successfully Telneting 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. For detailed configuration commands,
refer to the related modules in the command manual.
