Commands for Managing the Switch
enable ssh2
enable ssh2
{port <tcp_port_number>}
Description
Enables incoming SSH2 Telnet sessions.
Syntax Description
Default
The SSH2 feature is disabled until you obtain a valid security license. If a valid security license is in
effect, SSH2 is enabled with no access proÞle and uses TCP port number 22.
Usage Guidelines
You must enable SSH2 on the switch before you can connect to it using an external SSH2 client.
Because SSH2 is currently under U.S. export restrictions, you must Þrst obtain a security-enabled
version of the ExtremeWare software from Extreme Networks before you can enable SSH2. The
procedure for obtaining a security-enabled version of the ExtremeWare software is described in the
ExtremeWare Software User Guide.
You must have administrator privileges to issue this command.
NOTE
Using SSH2 requires an authentication key.
Before you issue this command, you should generates an SSH2 authentication key using the configure
ssh2 key
command. If an authentication key has not already been conÞgured, the enable ssh2
command will automatically start the dialog for generating an authentication key (which can take up to
40 minutes).
Use the port option to specify a TCP port number other than the default.
You must use the build command to commit the conÞguration changes made by this command.
Example
The following command enables the SSH2 feature, with access allowed based on the access proÞle
management:
enable ssh2 management
port The TCP port number to be used for SSH2 communication. The default is
port 22.
