request system software validate in-service-upgrade

Syntax

Description

Perform a compatibility check to ensure that the software and hardware components and the configuration on the device support unified ISSU. The request system software validate in-service-upgrade command enables you to detect any compatibility issues before actually issuing the request system software in-service-upgrade command to initiate unified ISSU.

Options

package-name

Location from which the software package or bundle is to be installed. For example:

/var/tmp/package-name—For a software package or bundle that is being installed from a local directory on the router.
protocol://hostname/pathname/package-name—For a software package or bundle that is to be downloaded and installed from a remote location. Replace protocol with one of the following:
- ftp—File Transfer Protocol
- http—Hypertext Transfer Protocol
- scp—Secure copy (available only for Canada and U.S. version)

enhanced-mode

(Optional) Checks for compatibility with enhanced mode—a mode of ISSU that eliminates packet loss during the unified ISSU process.

The enhanced mode option is available on MPC7E, MPC8E, and MPC9E line cards starting from Junos OS Release 20.1R1. Support for MPC11E line cards is provided from Junos OS Release 21.4R1 onwards.
