4. Configure the image server settings described in the table above, then click Apply to save your changes.
5. Click the Verify button at the bottom of the Maintenance > Controller > Image Management > Local
Configuration page. When you verify the upgrade profile, the master switch attempts to connect to the
file server, download the different images for each unique local switch and verify the validity of the image.
Once switch images are “verified” by the master switch, the local switches that are in the upgrade target list
connect to the file server, download the appropriate image, and upgrade their software to the downloaded
version.
Next, specify which local switches should download the image from the image server. You can allow all local
switches on the master to download an image from the upgrade server, or configure this feature to allow only
switches with a specified IP address or subnet to download the image. The upgrade target switches are
configured in the Upgrade Target section of the Maintenance > Controller > Image Management >
Local Configuration page.
n Allow All Targets: To allow all local switches associated with that master to download an image from the
image server, select the all option in the Upgrade Target section.
n Select Targets by IP address/Subnet: To allow local switches with a specific IP address or subnet mask to
download the image:
1. Click New.
2. Enter the IP address of a switch or the subnet mask of a group of local switches.
3. Click Add.
4. (Optional) Repeat steps 1-3 to add a new target.
5. Click Apply to save your changes.
