Console#
Information passed on to the switch from a DHCP server may also include a
configuration file to be downloaded and the TFTP servers where that file can be
accessed. If the Factory Default Configuration file is used to provision the switch at
startup, in addition to requesting IP configuration settings from the DHCP server, it
will also ask for the name of a bootup configuration file and TFTP servers where
that file is stored.
If the switch receives information that allows it to download the remote bootup file,
it will save this file to a local buffer, and then restart the provision process.
Note the following DHCP client behavior:
◆
The bootup configuration file received from a TFTP server is stored on the
switch with the original file name. If this file name already exists in the switch,
the file is overwritten.
◆
If the name of the bootup configuration file is the same as the Factory Default
Configuration file, the download procedure will be terminated, and the switch
will not send any further DHCP client requests.
◆
If the switch fails to download the bootup configuration file based on
information passed by the DHCP server, it will not send any further DHCP client
requests.
◆
If the switch does not receive a DHCP response prior to completing the bootup
process, it will continue to send a DHCP client request once a minute. These
requests will only be terminated if the switch's address is manually configured,
but will resume if the address mode is set back to DHCP.
