52 CHAPTER 3: SETTING UP FOR MANAGEMENT
Setting Up
Command Line
Interface
Management using
SSH
This section describes how you can set up Command Line Interface
management using SSH over a network.
To manage a Switch using the command line interface over a network
using SSH:
1 Ensure you have already set up the Switch with IP information as
described in “Setting Up Overview” on page 36.
2 Check that you have the IP protocol correctly installed on your
management workstation. You can check this by trying to browse the
World Wide Web. If you can browse, the IP protocol is installed.
3 Check you can communicate with the Switch by entering a ping
command at the DOS prompt in the following format:
c:\ ping xxx.xxx.xxx.xxx
(where xxx.xxx.xxx.xxx is the IP address of the Switch)
If you get an error message, check that your IP information has been
entered correctly and the Switch is powered up.
The switch automatically generates a host key pair when it is powered up
for the first time, or after any reset to factory defaults. Host key
generation may take a while, during which time SSH connections to the
switch will be refused.
4 Install an SSH client application on the workstation you want to use to
access the switch.
3Com recommends the following SSH clients; PuTTY, OpenSSH and SSH
Communications Security Corp Secure Shell.
5 Open an SSH session and access the switch using the switch’s IP address
and port number.
The first time you connect to the switch the client will ask you to confirm
that the host key is correct for the device.
6 The switch and the SSH client will authenticate each other and a secure
connection will be established.
7 Enter your usual username and password to access the CLI commands.
For increased security please change the default password when using
SSH for the first time.
