Description

Syntax Description
Default
N/A
Usage Guidelines
You must be running a security-enabled version of ExtremeWare 6.2.1 or later (which is under Export
Control) in order to use the SSH2 client command.
SSH2 does not need to be enabled on the switch in order to use this command.
Typically this command is used to establish a secure session to a remote switch. You will be prompted
for your password. Once you have logged in successfully, all ExtremeWare commands you enter will be
executed on the remote switch. When you terminate the remote session, commands will then resume
being executed on the original switch.
The remote command option cannot be used with Extreme Networks switches. If you include a remote
command, you will receive an error message.
The default settings for SSH2 parameters are as follows:
• cipher—3DES
• port—22
3des Specifies that the 3des cipher should be used for encryption. This is the default.
blowfish Specifies that the blowfish cipher should be used for encryption.
portnum Specifies the TCP port number to be used for communicating with the SSH2 client. Default
is port 22.
compression
on
specifies that data is to be compressed.
off
specifies that compression is not to be used. Default is
off
.
username Specifies a login name for the remote host, as an alternate to the user@host parameter.
debug_level Specifies a debug level. Default is 0.
username Specifies a login name for the remote host. May be omitted if it is the same as the
username on the switch.
host Specifies the name of the remote host.
ipaddress Specifies the IP address of the remote host.
remote command Specifies a command to be passed to the remote system for execution. Remote
commands are not supported on switches. This option is only valid if the remote system is
a system, such as a UNIX workstation, that can accept remote commands.
