one member ID for a compatible upgrade and can specify multiple member IDs for an incompatible
upgrade. As a best practice, specify half of the subordinate members if the member devices form a
ring. Make sure the specified subordinate members are directly connected by physical links.
reboot: Uses the reboot method for the upgrade. For an incremental upgrade, specify this keyword if
you want to use the reboot upgrade method. If you do not specify this keyword, the recommended
upgrade method is used.
Usage guidelines
You may upgrade all or some of the software images. If you are upgrading only some of the images,
make sure the new images are compatible with the images that are not to be upgraded. The upgrade
will fail if a conflict exists.
This command performs the following operations:
• Checks the version compatibility.
• Identifies the upgrade method.
• Loads the new images to upgrade the member devices.
• Sets the new images as the main startup software images so the upgrade can survive a reboot.
At reboot, a subordinate device automatically synchronizes the master device's configuration and
status data. You must wait for the synchronization to complete before using the issu load command
on the subordinate device. To identify whether the synchronization is complete, use the display
system stable state command. The synchronization is complete if the System State field displays
Stable.
Examples
# Upgrade member device 2 (a subordinate member) with feature image file flash:/feature1.bin. (In
this example, the image is compatible with the running images.)
<Sysname> issu load file feature flash:/feature1.bin slot 2
This operation will delete the rollback point information for the previous upgrade and
maybe get unsaved configuration lost. Continue? [Y/N]:Y
