Telnetting to Another Access controller from the Current One
You can Telnet to another access controller switch interface board from the current access controller
switch interface board. In this case, the current switch interface board operates as the client, and the
other operates as the server. If the interconnected Ethernet ports of the two switch interface boards are
in the same LAN segment, make sure the IP addresses of the two Ethernet ports are of the same
network segment, or the route between the two ports is available.
As shown in Figure 2-7 , after Telnetting to an access controller (labeled as Telnet client), you can
Telnet to another access controller (labeled as Telnet server) by executing the telnet command and
then to configure the latter.
Figure 2-7 Network diagram for telnetting to another access controller switch interface board from the
current one
Step 1: Configure the user name and password for Telnet on the access controller switch interface
board operating as the Telnet server. Refer to section
Telnet Configuration with Authentication Mode
Being None , section Telnet Configuration with Authentication Mode Being Password , and section Telnet
Configuration with Authentication Mode Being Scheme for more. By default, Telnet users need to pass
the password authentication to login.
Step 2: Telnet to the access controller operating as the Telnet client.
Step 3: Execute this command on the access controller operating as the Telnet client: telnet xxxx,
where xxxx is the IP address or the host name of the access controller switch interface board operating
as the Telnet server. You can use the ip host to assign a host name to a access controller.
Step 4: Enter the password. If the password is correct, the CLI prompt (such as <H3C>) appears. If all
VTY user interfaces of the access controller are in use, you will fail to establish the connection and
receive the message that says “The number of users currently using the system configuration has
reached the maximum. Please wait until one of the users releases the system configuration”.
Step 5: After successfully Telnetting to the access controller, you can configure the access controller or
display the information about it by executing corresponding commands. You can also type ? at any time
for help. Refer to Basic Configuration Commands.chapter in System Maintaining and Debugging in
