engine are in use, you will fail to establish the connection and see the message “All user interfaces
are used, please try later!” The switching engine of the device can accommodate up to five Telnet
connections at same time.
6) After successfully Telnetting to the switching engine, you can configure the switching engine or
display the information about the switching engine by executing corresponding commands. You
can also type ? at any time for help. Refer to the relevant parts in this manual for the information
about the commands.
z
A Telnet connection is 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. For the
command hierarchy and command views, refer to CLI in H3C WX3000 Series Unified Switches
Switching Engine Configuration Guide .
Telnetting to the Switching Engine from the Access Control Engine
You can Telnet to the switching engine from the access control engine. In this case, the access control
engine operates as the client, and the switching engine operates as the server. If the interconnected
Ethernet ports of the two engines are in the same LAN segment, make sure the IP addresses of the two
management VLAN interfaces to which the two Ethernet ports belong are of the same network segment,
or the route between the two VLAN interfaces is available.
As shown in Figure 4-8 , after Telnetting to the access control engine (labeled as Telnet client), you can
Telnet to the switching engine (labeled as Telnet server) by executing the telnet command and then
configure it.

2) Perform Telnet-related configuration on the switching engine operating as the Telnet server. For
details, refer to Telnet Configuration with Authentication Mode Being None, Telnet Configuration
with Authentication Mode Being Password, and Telnet Configuration with Authentication Mode
Being Scheme.
3) Telnet to the access control engine as the Telnet client.
4) Execute the following command on the access control engine operating as the Telnet client:
<device> telnet xxxx
Note that xxxx is the IP address or the host name of the access control engine operating as the Telnet
server. You can use the ip host to assign a host name to the access control engine.
