Management and Configuration Guide K/KA/KB.15.15

The destination device and copy method options are as follows (CLI keyword is in bold):
• Remote Host via TFTP.
• Physically connected USB flash drive via the switch's USB port.
• Serially connected PC or UNIX workstation via Xmodem.
Behavior of autorun when USB port is disabled
Software versions K.13.XX operation
When using software version K.13.58, if the USB port is disabled (no usb-port command), the
USB autorun function does not work in the USB port until the USB port is enabled, the config file
is saved, and the switch is rebooted. The 5-volt power to the USB port remains on, even after the
USB port has been disabled.
For software versions after K.13.58, the 5-volt power applied to the USB port is synchronized with
the enabling of the USB port, that is, when the USB port is enabled, the 5 volts are supplied; when
the USB port is disabled, the 5 volts are not supplied. For previous software versions, the power
was supplied continuously. The autorun function does not require a switch reboot, but the USB
device must be inserted at least once after the port is enabled so the switch recognizes that the
device is present. If the USB device is inserted, and then the USB port is enabled, the switch does
not recognize that a USB device is present.
Software version K.14.XX operation
For software versions K.14.XX, the USB port can be disabled and enabled without affecting the
autorun feature. When the USB port is enabled, the autorun feature activates if a USB device is
already inserted in the USB port.
Power is synchronized with the enabling and disabling of USB ports as described above for
K.13.59 and later software.
Using USB autorun
USB autorun helps ease the configuration of HP Switch switches by providing a way to auto-execute
CLI commands from a USB flash drive. Using this solution, you can create a command file (also
known as an AutoRun file), write it to a USB storage device, and then execute the file simply by
inserting the USB device into the switch's 'Auxiliary Port.' The AutoRun file is executed automatically
when autorun is enabled on the switch and can be designed for various purposes, such as to
configure the switch, to update software, or to retrieve diagnostic logs for troubleshooting purposes.
The overall USB autorun solution requires the following components:
• An HP Switch switch that can securely use USB autorun to load authorized configurations and
write reporting information. This requires software versions K.13.01, T.13.01 or greater.
• The network management application HP Switch Manager Plus (PCM+.) PCM+ is required to
create a valid AutoRun file and to view the results after the file has been executed on the
switch.
• A non-proprietary USB flash drive.
Security considerations
By default, the switch is unsecured when shipped (that is, USB autorun is enabled by default.)
However, as soon as an operator or manager password is configured, autorun is disabled and
must be re-enabled at the configuration level of the CLI before it can be used. The requirement to
use PCM+ to create a valid AutoRun file helps prevent a nonauthorized command file from being
created and processed by the switch.
