Hotfix is a fast, cost-effective method to repair software
defects of a device.
Compared with software version upgrade, hotfix can
upgrade the software without interrupting the running
services of the device. In other words, it can repair the
software defects of the current version without rebooting
the device.
The patch files match the switch model and software
version. If they are not matched, the hotfixing operation
fails.
ISSU enables software upgrade and ensures continues
packet forwarding.
For more information, see the chapter "ISSU
configuration."
