Enabling Software Auto-Update For Software Image Synchronization - H3C MSR 5600 Configuration Manual

Configuring IRF bridge MAC persistence
1. Enter system view.
system-view
2. Configure IRF bridge MAC persistence.
Retain the bridge MAC address permanently even if the address owner has left the fabric.

irf mac-address persistent always
Retain the bridge MAC address for 6 minutes after the address owner leaves the fabric.

irf mac-address persistent timer
Change the bridge MAC address as soon as the address owner leaves the fabric.

undo irf mac-address persistent
By default, the IRF bridge MAC address remains unchanged for 6 minutes after the address
owner leaves.
The
irf mac-address persistent timer
address changes caused by device reboot, transient link failure, or purposeful link
disconnection.
Enabling software auto-update for software image
synchronization
About this task
The software auto-update feature automatically propagates the software images of the global active
MPU to all other MPUs (including new devices) in the IRF fabric.
To join an IRF fabric, an MPU must use the same software images as the global active MPU in the
fabric.
When you add an MPU to the IRF fabric, software auto-update compares the startup software
images of the MPU with the current software images of the IRF global active MPU. If the two sets of
images are different, the MPU automatically performs the following operations:
1. Downloads the current software images of the global active MPU.
2. Sets the downloaded images as the main startup software images.
3. Reboots with the new software images to rejoin the IRF fabric.
You must manually update the new MPU with the software images running on the IRF fabric if
software auto-update is disabled.
NOTE:
To synchronize software from the active MPU to the standby MPU in standalone mode, use the
undo version check ignore
information about these commands, see Fundamentals Configuration Guide.
Restrictions and guidelines
To ensure a successful software auto-update in a multi-user environment, prevent anyone from
rebooting or swapping member devices or MPUs during the auto-update process. To inform
administrators of the auto-update status, configure the information center to output the status
messages to configuration terminals (see Network Management and Monitoring Configuration
Guide).
Make sure the MPU you are adding to the IRF fabric has sufficient storage space for the new
software images.
