Upgrading the system software (for IRF mode)
Step Command Remarks
1. Use FTP, TFTP, or any other
method to transfer the system
software image to the root
directory of a storage medium
on the global active MPU.
See "Configuring FTP" or
"Configuring TFTP."
The image file must be saved in the
storage medium's root directory for
a successful upgrade.
2. Copy the system software
image to the root directory of
a storage medium on the
standby MPUs.
copy fileurl-source fileurl-dest
You can assign different names to
the image files for the active MPU
and the standby MPUs, but you
must make sure the image versions
are the same.
3. Specify the file as a startup
system software image on
each MPU in user view.
boot-loader file file-url chassis
chassis-number slot slot-number
{ main | backup }
In FIPS mode, the specified file
must pass authenticity verification
before it can be set as a startup
system software image.
4. Reboot the router.
reboot N/A
Synchronizing the standby MPU with the system
software on the active MPU
The standby MPU must have the same software version as the active MPU to work correctly.
To synchronize the standby MPU with the system software on the active MPU:
1. Use the display device command to examine the state of the standby MPU.
{ If its state is Fault, upgrade the standby MPU from the Boot menu or remove the standby MPU
and upgrade it.
{ If its state is Slave, go to the next step.
2. Examine the storage space of the standby MPU to make sure that the sum of free storage space
plus the size of the current system software image is equal to or greater than the size of the new
system software image. If not, the upgrade will fail.
3. Execute the boot-loader update slot slot-number command in user view.
The system copies the system software image on the active MPU to the standby MPU, and reboots
the standby MPU with the new system software image.
Installing hotfixes
Hotfixes (called "patches" in this document) repair software defects without requiring a system reboot.
