Downloads a new version of the ExtremeXOS software image or a new Fabric Engine image when changing the switch's network operating system.
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 the file to download, which is of a supported type (for example, cfg, lic, lst, pol, py, Fabric Engine, xmod, xos, xsf, xtr). |
| url | Specifies the URL of the supported file (for example, http://ipaddress/path.xos or ftp://ipaddress:port/path.xmod or ftp://ipaddress/some_list.lst) |
| active |
Specifies automatic determination for active (primary) partition. Note: Not
applicable Fabric Engine specifying a Fabric Engine
image.
|
| inactive |
Specifies automatic determination for inactive (secondary) partition. Note: Not
applicable when specifying a Fabric Engine image.
|
| 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. |
| filename |
Specifies the file name of the new image. Uou can use this command to change the operating system to Fabric Engine by downloading and installing a Fabric Engine 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
Switch Engine v33.1.1 Licensing Guide
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. Note: Not
applicable when specifying a Fabric Engine image.
|
| install | Specifies installing the image after download. |
| reboot | Specifies rebooting after installation. |
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 1,400 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
The download image command 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 IP address or host name parameters to download an image from a TFTP server on the network. Use of the host name parameter requires that DNS be enabled.
When you download and install a new version of an ExtremeXOS image, the system automatically compares the currently installed bootROM image against the bootROM image contained in the new ExtremeXOS image. If the installed version is older, the system automatically upgrades to the bootROM version contained in the new ExtremeXOS image.
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 a Switch Engine core image, or an .xmod file, which contains a Switch Engine modular software package.
For additional installation requirements, see the sections Installing a Core Image and Installing a Modular Software Package in the . Switch Engine v33.1.1 User Guide .
Caution
Changing your network operating systems deletes all configuration files, debug information, logs, events, statistics, and license information of the previous network operating system.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 canceled
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 canceled
Warning: Signature Validation - Certificates verification failed; Image signature validation will be bypassed. Do you want to continue? (y/N)
If you decide to continue, the normal installation continues. If you decide to stop here, the following message appears and the installation is canceled.
Installation canceled
Error: Failed to download image - Error: Image signature cannot be validated.
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 ExtremeXOS is currently running from the selected partition, the command is not executed and the following message appears:
Error: the image partition selected must not be the active partition.
For information about upgrading .xos and .xmod images, see the Software Upgrade and Boot Options section in the Switch Engine v33.1.1 User Guide .
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.
