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 Boot menu to delete files.
Configuration procedure
To enable software auto-update:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable software
auto-update.
irf auto-update enable
By default, software auto-update is
enabled.
Setting the IRF link down report delay
To prevent frequent IRF splits and merges when IRF links flap, 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.
To set the IRF link down report delay:
Step Command Remarks
1. Enter system view. system-view N/A
2. Set the IRF link down report
delay.
irf link-delay interval
By default, an IRF port does not delay any IRF
link down reports.
If the BFD feature is used in the IRF fabric, make
sure the delay interval is shorter than the BFD
session lifetime. For more information about
BFD, see High Availability Configuration Guide.
Configuring MAD
When you configure MAD, follow these restrictions and guidelines:
• You can configure BFD MAD, ARP MAD, and ND MAD together in an IRF fabric for prompt IRF split
detection.
• If ARP MAD or ND MAD runs between two IRF fabrics, assign each fabric a unique IRF domain ID.
(For BFD MAD, this task is optional.)
• An IRF fabric has only one IRF domain ID.
{
You can change the IRF domain ID by using the following commands: irf domain, mad arp
enable, or mad nd enable. The IRF domain IDs configured by using these commands overwrite
each other.
