158 Configuring System Information
Auto-Update/Configuration also enables quick installation of new devices on
the network, since an out-of-box device can be configured to retrieve its
configuration file from the network, allowing instant access to it from the
administrator's management station and up-to-date configuration on the
device.
Triggering the Auto Update of Configuration/Image File Process
When the Auto-Update/Configuration feature is enabled (in the Auto
Update of Configuration/Image File page), the device automatically attempts
to download a new image or configuration file (under certain circumstances)
using one of the following processes:
• The Auto-Update from a TFTP server is triggered if the following
conditions are fulfilled:
– An IP address of a TFTP server is received from a DHCP server.
– A file name is received from DHCP server.
• The Auto-Configuration from a TFTP server is triggered if the following
conditions are fulfilled:
– The switch as DHCP client received a configuration file name or a
TFTP URL.
– Force Configuration Download at Next Startup enabled by the boot
host dhcp command, or, the Startup Configuration file is empty.
See Preparations for Using Auto Configuration from a TFTP Server.
Automatic DHCP IP Interface Assignment
The user can manually define a DHCP interface in the DHCP IPv4 page.
If the user does not do this, the switch automatically creates a DHCP
interface on the VLAN with the lowest VLAN ID that does not have an IP
address defined on it after boot if both of the following conditions are
fulfilled:
• There is no DHCP IP interface.
• There is a VLAN without an IP address.
