Setting The Irf Link Down Report Delay - HP 5120-24G EI Configuration Manual

The software auto-update function automatically propagates the system software image of the master to
all members in the IRF fabric. If software auto-update is disabled, you must manually update the switch
with the system software image of the master.
When you add a switch to the IRF fabric, the software auto-update function compares the system
software versions of the switch and the IRF master. If the versions are different, the switch automatically
downloads the system software image from the master, sets the downloaded image as the system
software for the next startup, and automatically reboots with the new system software image to re-join the
IRF fabric.
Before you use the software auto-update function, make sure:
• The switch you are adding to the IRF fabric is compatible with the software version running on the
master. If not, the automatic system software upgrading function cannot correctly work.
The switch you are adding to the IRF fabric has sufficient space for the new system software image.
•
To enable the IRF fabric to automatically synchronize the system software of the master to the switch you
are adding to the IRF fabric:
Step
1. Enter system view.
2. Enable the software
auto-update function.
In an IRF fabric enabled with software auto-update, if a software upgrade requires upgrading the Boot
ROM image, use the following upgrading procedure:
Download the new system software image to the master device.
1.
Use the bootrom update command to upgrade the Boot ROM image on the master.
2.
This step guarantees that the master can complete startup prior to other member switches.
Use the boot-loader file file-url slot slot-number main command to specify the system software
3.
image as the startup image for the master.
Reboot the entire IRF fabric to complete upgrading software.
4.
For the system software image and Boot ROM compatibility, see the release notes for the new software
release.

Setting the IRF link down report delay

You can avoid IRF link flapping causing frequent IRF splits and merges during a short time by configuring
the IRF ports to delay reporting link down events. An IRF port works as follows:
• When the IRF link changes from up to down, the port does not immediately report the change to the
IRF fabric. If the IRF link state is still down when the delay time is reached, the port reports the
change to the IRF fabric.
When the IRF link changes from down to up, the link layer immediately reports the event to the IRF

fabric.
