Loading A Patch; Activating A Patch - Huawei netengine80e Configuration Manual

HUAWEI NetEngine80E/40E Router
Configuration Guide - Basic Configurations
Applicable Environment
When installing a patch, it is recommended to specify all to install the patch for all boards at
one time rather than specify slot to install the patch for boards one by one. In some special
scenarios, you must specify slot to install a patch for the master and slave MPUs, and then for
all LPUs one by one.
Installing patches can fix system vulnerabilities or correct system defects. By installing a patch,
you can upgrade the system without upgrading the system software.
When a patch is uploaded, the system checks that the patch version is the same as the system
version. If the two versions are not the same, the system prompts that the patch uploading fails.
Pre-configuration Tasks
Before installing a patch, upload the patch to the root directory of the CF card of the master and
slave MPUs.
Data Preparation
None
