Enabling Software Auto-Update For System Software Image Synchronization - HP 12500 SERIES Configuration Manual

Depending on your network condition, enable the IRF fabric to preserve or change its bridge MAC
address after the master leaves. Available options include:
irf mac-address persistent timer—Bridge MAC address of the IRF fabric persists for 6 minutes
•
after the master leaves. If the master does not come back before the timer expires, the IRF
fabric uses the bridge MAC address of the new master as its bridge MAC address. This option
avoids unnecessary bridge MAC address change due to a device reboot, transient link failure,
or purposeful link disconnection.
irf mac-address persistent always—Bridge MAC address of the IRF fabric does not change
•
after the master leaves.
undo irf mac-address persistent—Bridge MAC address of the new master replaces the
•
original one as soon as the old master leaves.
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 VRRP load balancing or RPR is used, configure the the irf mac-address persistent always
•
command to prevent the IRF bridge MAC address from changing.
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 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 automatically downloads the current software images of the
master, sets the downloaded images as the main startup software images, and automatically
reboots with the new software images to rejoin the IRF fabric.
Command
system-view
•
Keep the bridge MAC address
unchanged 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
N/A
By default, the IRF fabric's
bridge MAC address persists
permanently even after the
master leaves.
