Setting The Irf Link Down Report Delay; Removing An Expansion Interface Card That Has Irf Physical Interfaces - H3C MSR 5600 Configuration Manual

If sufficient storage space is not available, the MPU automatically deletes the current software
images. If the reclaimed space is still insufficient, the MPU cannot complete the auto-update. You
must reboot the device that holds the MPU, and then access the BootWare menu to delete files.
Procedure
1. Enter system view.

2. Enable software auto-update.
irf auto-update enable
By default, software auto-update is enabled.

Setting the IRF link down report delay

About this task
To prevent frequent IRF splits and merges during link flapping, configure the IRF ports to delay
reporting link down events.
An IRF port does not report a link down event to the IRF fabric immediately after its link changes from
up to down. If the IRF link state is still down when the delay is reached, the port reports the change to
the IRF fabric.
IRF ports do not delay link up events. They report the link up event immediately after the IRF link
comes up.
Restrictions and guidelines
Make sure the IRF link down report delay is shorter than the heartbeat or hello timeout settings of
upper-layer protocols (for example, CFD and OSPF). If the report delay is longer than the timeout
setting of a protocol, unnecessary recalculations might occur.
Set the delay to 0 seconds in the following situations:
•
The IRF fabric requires a fast master/subordinate or IRF link switchover.
•
The BFD or GR feature is used.
•
You want to shut down an IRF physical interface or reboot an IRF member device. (After you
complete the operation, reconfigure the delay depending on the network condition.)
Procedure
1. Enter system view.

2. Set the IRF link down report delay.
irf link-delay interval
By default, the IRF link down report delay is 0 milliseconds.
Removing an expansion interface card that has IRF physical
interfaces
To remove an expansion interface card that provides IRF physical interfaces:
1. Perform one of the following tasks to eliminate temporary packet loss:
Remove cables from the IRF physical interfaces on the card.
