5)If the password authentication mode is specified, enter the password when the Telnet window displays “Login authentication” and prompts for login password. The CLI prompt (such as <System_LSW>) appears if the password is correct. If all VTY user interfaces of the switching 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.

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 Operation in this manual.

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 3-8, 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.
