Description
Use the irf auto-update enable command to enable the auto update of boot files for an IRF virtual
device.
Use the undo irf auto-update enable command to disable this function.
This function is enabled by default.
Note the following:
Ensure that the device and the master have the same software version before adding a device
into the IRF virtual device.
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 automatically reboots.
Because system boot file occupies large memory space, to make the auto upgrade succeed,
ensure that there is enough space on the storage medium of the slave.
If the downloaded boot file and the local boot file have duplicate file names, the local file is
overwritten. Therefore, ensure that there is not any local file that has the same name as the boot
file to be downloaded.
Field
Indicates that this output information is generated by a slave.
Describes the master/slave switchover state of the slave.
The slave is ready, and is waiting to enter the batch backup
state.
