Enabling Software Auto-Update For System Software Image Synchronization - HPE FlexNetwork HSR6800 Configuration Manual

IMPORTANT:
If ARP MAD is used, configure the undo irf mac-address persistent command to enable
immediate bridge MAC address change after a master leaves.
If two IRF fabrics have the same bridge MAC address, they cannot merge.
To configure the IRF bridge MAC persistence setting:
Step
1. Enter system view.
2. Configure IRF bridge MAC
persistence.
Enabling software auto-update for system software image
synchronization
The software auto-update function automatically propagates the system software image of the
master to all members in the IRF fabric.
To join an IRF fabric, a device must use the same system software image as the master in the fabric.
When you add a device to the IRF fabric, the software auto-update function compares the system
software versions of the device and the IRF master. If the versions are different, the device
automatically downloads the system software image from the master, sets the downloaded image as
the system software for the next reboot, and automatically reboots with the new system software
image to rejoin the IRF fabric.
If software auto-update is disabled, you must manually update the device with the system software
image of the master.
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 system software upgrading function cannot
correctly work.
•
The device you are adding to the IRF fabric has sufficient space for the new system software
image.
Configuration procedure
To enable an IRF fabric to automatically synchronize software images of the master to the devices
you are adding to the IRF fabric:
Command
system-view
•
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
21
Remarks
N/A
By default, the IRF fabric's
bridge MAC address is retained
permanently even after the
master leaves.
