Switch Management Commands 2294
USB Flash Drive Commands
When available, a USB flash drive can be used to configure, upgrade and
provide consistency to a switching network. A USB flash drive can be plugged
in sequentially to a set of routers/switches to upgrade to newer software
versions without depending on the network to upgrade the switches with new
firmware. New switches can be preloaded with configuration prior to
deployment.
The USB Configuration Port provides access to an optional secondary storage
capability to the switch. A USB flash drive can be used to store and deploy
configurations and images from USB flash drive to the switch. A USB flash
drive can be used easily to move and copy configuration and image files from
one switch to other. Files from the switch can be copied to a USB flash device
and can be used to deploy on other switches in the network.
Validation of Files Downloaded/Uploaded from
USB Device
Image files are validated before downloading from the USB flash drive to the
switch. Files other than image files and scripts are copied with no validation.
Downloaded image files will be validated against the following conditions:
• File exists- Check if the file being downloaded from the USB flash drive
exists on the device.
• Valid CRC checksum.- Verify CRC for the file downloaded from the
USB flash drive to switch.
• Valid STK format - Check if the file is of type STK.
• Target device validation – Check if the file being downloaded is
compatible with the target switch.
Validation for Files Uploaded from Switch to USB
Flash Drive
• Memory insufficient -Check memory availability on the USB flash drive
to upload the file.
