Configuring Break Pass Through, 109 | Black Box 16 port, 24 port

Configuring Break Pass Through

The Console Server will not send break signals on power cycles. It is also configured not to allow break signals to be sent through to attached devices by default. However, some administrators may wish to be able to send the break signal i.e. to take a Sun Solaris system to the Open Boot prompt.

To enable this feature, please use the following CLI command to enable/disable proprietary inband SSH break signal processing as well as existing Reverse Telnet break signal.

#set server break <on/off>

#save

The OEM mode flag 0x0010 will be set/reset based upon this command. Alternatively, you can enable/disable this feature but using "set server OEM_mode".

A break signal is generated on a specific serial port only when the server's break option is enabled and the user has typed the exact break string over a reverse SSH connection.

The OEM mode flag 0x0010 will be set/reset based upon this command. Alternatively, you can enable/disable this feature but using "set server OEM_mode".

For SSH, the default break signal is '~break', where ~ is tilde. To change the SSH break signal, use the following command:

# set server sshbreakstring <8-characters>

Note A terminal emulator must be used that is capable of sending the break signal.
