Enabling Software Auto-Update For System Software Image Synchronization - HP 10500 Series Configuration Manual

Step
2. Configure IRF bridge MAC
persistence.
Enabling software auto-update for system software image
synchronization
IMPORTANT:
To ensure a successful software auto-update in a multi-user environment, prevent the action of swapping
or rebooting MPUs during the software auto-update process. You can configure the information center to
output the software auto-update status to configuration terminals (see
Monitoring Configuration Guide
To synchronize software from the active MPU to the standby MPU in standalone mode, use the undo
version check ignore and version auto-update enable commands. For more information, see
Fundamentals Configuration Guide.
To synchronize software from the global active MPU to other MPUs on an IRF fabric, use the software
auto-update function in this section.
The software auto-update function automatically propagates the software images of the master to all
members in the IRF fabric.
To join an IRF fabric, a device must use the same set of software images as the master in the fabric.
When you add a device to the IRF fabric, the software auto-update function compares the startup
software images of the joining device with the current software images of the IRF master. If the two sets
of images are different, the device performs the following tasks automatically:
1. Downloads the current software images of the master.
2. Sets the downloaded images as the main startup software images.
3. Reboots with the new software images to rejoin the IRF fabric.
If software auto-update is disabled, you must manually update the device with the software images of the
master before adding it to the IRF fabric.
Configuration prerequisites
Before you use the software auto-update function, verify the following items:
The device you are adding to the IRF fabric is compatible with the software version running on the
•
master. If it is not compatible, the automatic software upgrading function cannot correctly work.
• The device you are adding to the IRF fabric has sufficient space for the new software images.
Command
•
Retain the bridge MAC address
even if the master has changed:
irf mac-address persistent always
•
Preserve the bridge MAC address
for 6 minutes after the master
leaves:
irf mac-address persistent timer
•
Change the bridge MAC address
as soon as the master leaves:
undo irf mac-address persistent
).

Remarks
By default, the IRF fabric's
bridge MAC address is retained
permanently even after the
master leaves.
