Secure Shell 2 (SSH2)
ExtremeWare 7.2e Installation and User Guide 179
The user must have administrator-level access to the switch. The switch can be specified by its switch
name or IP address.
Configuration or image files stored on the system running the SSH2 client may be named as desired by
the user. However, files on the switch have predefined names, as follows:
•
configuration.cfg
—The current configuration
•
incremental.cfg
—The current incremental configuration
•
primary.img
—The primary ExtremeWare image
•
secondary.img
—The secondary ExtremeWare image
•
bootrom.img
—The BootROM image
For example, to copy an image file saved as image1.xtr to switch with IP address 10.10.0.5 as the primary
image using SCP2, you would enter the following command within your SSH2 session:
scp image1.xtr admin@10.20.0.5:primary.img
To copy the configuration from the switch and save it in file config1.save using SCP, you would enter the
following command within your SSH2 session:
scp admin@10.10.0.5:configuration.cfg config1.save
SSH2 Client Functions on the Switch
In ExtremeWare version 6.2.1 or later, an Extreme Networks switch can function as an SSH2 client. This
means you can connect from the switch to a remote device running an SSH2 server, and send
commands to that device. You can also use SCP2 to transfer files to and from the remote device.
You do not need to enable SSH2 or generate an authentication key to use the SSH2 and SCP2
commands from the ExtremeWare CLI.
To send commands to a remote system using SSH2, use the following command:
ssh2 {cipher [3des | blowfish]} {port <portnum>} {compression [on | off]} {user
<username>} {debug <debug_level>} {<username>@} [<host> | <ipaddress>] {<remote
command>}
The remote commands can be any commands acceptable by the remote system. You can specify the
login user name as a separate argument, or as part of the user@host specification. If the login user name
for the remote system is the same as your user name on the switch, you can omit the username
parameter entirely.
To initiate a file copy from a remote system to the switch using SCP2, use the following command:
scp2 {cipher [3des | blowfish]} {port <portnum>} {debug <debug_level>} <user>@
[<hostname> | <ipaddress>] :<remote_file> [configuration {incremental} | image
[primary | secondary] | bootrom]
To initiate a file copy to a remote system from the switch using SCP2, use the following command:
scp2 {cipher [3des | blowfish]} {port <portnum>} {debug <debug_level>} configuration
<user>@ [<hostname> | <ipaddress>]:<remote_file>
