Downloads a new version of the ExtremeXOS software image.
The image file can be downloaded using TFTP (which is not a secure method), or SFTP and SCP2 (which are secure methods). The procedure using TFTP begins above and using SFTP/SCP2.
| url | Uniform Resource Locator (URL) of image, xmod or flat-text list of files with suffix '.lst'. |
| url | Image, xmod, or file list. e.g. http://ipaddress/path.xos or ftp://ipaddress:port/ path.xmod or ftp://ipaddress/some_list.lst. |
| active | Specifies automatic determination for active (primary) partition. |
| inactive | Specifies automatic determination for inactive (secondary) partition. |
| hostname | Specifies the hostname of the TFTP server from which the image should be obtained. |
| ipaddress | Specifies the IP address of TFTP server from which the image should be obtained. |
| memorycard | Specifies that the image should be obtained from a removable storage device, which can be a compact flash card or a USB 2.0 storage device. |
| filename | Specifies the filename of the new image. |
| vrname | Specifies the name of the
virtual router. Note: User-created VRs are
supported only on the platforms listed for this feature in the ExtremeXOS 22.2 Feature License Requirements document.
|
| block_size | Specifies the maximum block size, not including the TFTP header. The range is 24–65000 bytes. |
| partition | Specifies which partition the image should be saved to: primary or secondary. Select primary to save the image to the primary partition and secondary to save the image to the secondary partition. |
Stores the downloaded image in the alternate (inactive) partition.
SFTP and SCP2 provide secure methods of downloading the ExtremeXOS software image files, *.xos or *.xmod. You can use one of three procedures:
If you do not specify block size, the default value is 1400 bytes.
Prior to downloading an image on the switch, you must download the image you received from Extreme Networks to a TFTP server on your network. If your switch has a removable storage device, you can also download the image to that device.
Note
Unlike ExtremeWare, the download image command in ExtremeXOS causes the switch to use the newly downloaded software image during the next switch reboot. To modify or reset the software image used during a switch reboot, use the use image command. Use this command after downloading and installing the image for it to be effective.Specify the ipaddress or hostname parameters to download an image from a TFTP server on the network. Use of the hostname parameter requires that DNS be enabled.
Specify memorycard to download a an image from a removable storage device. Use a PC with appropriate hardware such as a compact flash reader/writer and follow the manufacturer‘s instructions to access the compact flash card and place the image onto the card. For more information about installing a removable storage device, see the hardware documentation.
A switch can store up to two core images: an active and inactive. When downloading a new image, you must select on which partition to install the new image. You must install the software image to the inactive partition, and must specify that partition while downloading the image to the switch.
The software image file can be an .xos file, which contains an ExtremeXOS core image, or an .xmod file, which contains an ExtremeXOS modular software package.
You can identify the appropriate image or module for your platform based on the file name of the image. The Summit and ExtremeSwitching switches use the summitX- filename prefix. The exceptions are the ExtremeSwitching X870 and X690 series switches, which use the onie- prefix (for example: onie-22.2.1.2.xos).
For additional installation requirements see the sections, Installing a Core Image and Installing a Modular Software Package.
To display the software image version running on the switch, use the show version or show switch commands.
This section provides information about the characters supported by the switch for host names and remote IP addresses.
When naming or configuring an IP address for your network server, remember the requirements listed above.
This section provides information about the characters supported by the switch for local and remote filenames.
When naming a local or remote file, remember the requirements listed above.
When you download a new image, you will see the following message:
Do you want to install image after downloading? (y - yes, n - no, <cr> - cancel)
The Image Integrity Check feature was added in ExtremeXOS 16.1. The CLI output of this command is modified:
Warning: Signature Validation - Image is not digitally signed. Do you want to continue? (y/N)
If the user decides to continue, then it follows the normal installation path; if the user decides to stop here, the following message is printed and then the installation is canceled.
Installation cancelled
Warning: Signature Validation - Certificates missing; Image signature validation will be bypassed. Do you want to continue? (y/N)
If the user decides to continue, then it follows the normal installation path; if the user decides to stop here, the following message is printed and then the installation is canceled.
Installation cancelled
Warning: Signature Validation - Certificates verification failed; Image signature validation will be bypassed. Do you want to continue? (y/N)
If the user decides to continue, then it follows normal installation path; if the user decides to stop here, the following message is printed and then the installation is canceled.
Installation cancelled
Error: Failed to download image - Error: Image signature cannot be validated.
If you configure the switch to write core dump (debug) files to the internal memory card and attempt to download a new software image, you might have insufficient space to complete the image download.
If this occurs, move or delete the core dump files from the internal memory. For example, if the switch supports a compact flash card or USB 2.0 storage device and space is available, transfer the files to the storage device. On switches without removable storage devices, transfer the files from the internal memory card to a TFTP server. This frees up space on the internal memory card while keeping the core dump files.
The switch displays a message similar to the following and prompts you to take action:
Core dumps are present in internal-memory and must be removed before this download can continue. (Please refer to documentation for the “configure debug core-dumps” command for additional information) Do you want to continue with download and remove existing core dumps? (y/n)
Enter y to remove the core dump files and download the new software image. Enter n to cancel this action and transfer the files before downloading the image.
For information about configuring and sending core dump information, see the configure debug core-dumps and save debug tracefiles memorycard commands.
You can issue this command only from the Master node.
If a slot is not specified, the image is downloaded to every node in the Active Topology. If a slot is specified, the image is downloaded to that slot only.
If all nodes to be downloaded are not running the same partition, the command is not executed and following message is displayed:
Error: all nodes do not have the same image partition selected.
If all nodes to be downloaded have the same partition selected but the EXOS is currently running from the selected partition, the command is not executed and the following message is displayed:
Error: the image partition selected must not be the active partition.
The ExtremeXOS 22.2 User Guide provides detailed steps for upgrading .xos and .xmod images. Refer to the Software Upgrade and Boot Options chapter for more information.
The following example shows how the .lst file can contain filenames ending in .lst to get a list of lists (of lists etc…) from an HTTP server on 10.68.9.7 port 8080 for directory 16.1/cougar/cougar/release:
A single download command downloads all of the above files.
