Accessing The Switch Through The Sshv2/Telnet Interface - Lenovo CN4093 User Manual

Accessing the Switch Through the SSHv2/Telnet Interface

© Copyright 2015 Lenovo
The switch supports a Command-Line Interface (CLI) that you can use to configure
and control the switch over the network through the SSHv2/Telnet client software.
You can use the CLI to perform many basic network-management functions. In
addition, you can configure the switch for management through an SNMP-based
network-management system.
If you know the IP address for the switch
CMM" on page 35) and you have an existing network connection, you can use the
SSHv2/Telnet client software from an external management station to access and
control the switch. The management station and the switch must be on the same IP
subnet. If you have to obtain the IP address for the switch or establish a network
connection, contact your system or network administrator.
The switch also supports user-based security that enables you to prevent
unauthorized users from accessing the switch or changing its settings.
To connect to the switch through the SSHv2/Telnet interface, refer to your client
software for specific instructions on how to invoke a session. For example, using the
Microsoft Telnet Client, you would complete the following steps:
1. From a DOS command-line prompt, type telnet <switch IP address> and press
Enter.
2. When prompted, enter your user name and password.
– When logging in to a switch for the first time, the default switch administrator
user name is USERID, and the default password is PASSW0RD (where the sixth
character is the number zero, not the letter O). The User ID and password
fields are case-sensitive. For security purposes, you will be prompted to
change the administrator password after the first successful login.
– Otherwise, if you have an assigned user account, use your assigned user
name and password.
Important: Any configuration changes made using the management interfaces will
be lost during the next switch reboot unless you execute the copy
running-config startup-config command. This command stores the
current switch configuration and all changes in nonvolatile memory.
For more information about configuring through the CLI, see the Application Guide
and Command Reference for your specific switch and its installed firmware.
