Setting The Irf Link Down Report Delay - H3C S9500E Series Configuration Manual

joins the IRF fabric again. If the downloaded boot file and the local boot file have duplicate file
names, the local file is overwritten.
To enable auto upgrade of boot files for an IRF fabric:
To do...
Enter system view
Enable auto upgrade of boot files
for an IRF fabric
CAUTION:
When you disable the auto upgrade of boot files, the software versions of the switches must be the same.
•
If not, an IRF fabric cannot be established.
Make sure that the model of the switch matches the software version of the master before adding the
•
switch into the IRF fabric. If the model of the switch to be added does not match the software version of
the master, auto upgrade may not function normally.
• After automatically loading the master's boot file, a slave configures the file as the boot file to be used
at the next boot and reboots automatically.
Make sure that there is enough space on the slave's flash or CF card where the system boot file resides
•
to make the auto upgrade succeeds.

Setting the IRF link down report delay

After setting the delay time for the link layer to report a link-down event:
If the IRF link state 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 configured time is reached, the port reports the
change to the IRF fabric.
If the link state changes from down to up, the link layer immediately reports the event to the IRF
•
fabric.
Use this function to avoid unnecessary IRF fabric partition and merge caused by frequent link state
changes of a port.
To set the IRF link down report delay:
To do...
Enter system view
Set the IRF link down report delay
CAUTION:
The recommended value of the
delay time too long can cause the IRF fabric to not address topology changes in time, which can slow the
recovery process.
