❑ Remote
If you choose the remote boot load mode, the switch downloads
software from a TFTP server and boots using the newly
downloaded management software.
Set Boot [M]ode
If you are using the remote boot load mode, you need to specify
how the stack should download the new management software.
There are two boot mode options: DHCP and TFTP.
When downloading the image:
❑ DHCP
The stack will get an IP address, TFTP server IP address, and a
filename from the DHCP server. The stack will then use this
information to connect to the TFTP server and download the
filename it received and boot the downloaded file as the image. If
this file does not exist, it uses the file which it last booted off of
successfully.
❑ TFTP
The stack will use the IP address it had prior to reboot to download
the image file from the server through TFTP using the information
configured in “Switch Tools -> Software Upgrade -> TFTP
Software Upgrade”.
When downloading the configuration:
The stack will get the TFTP server and file information from what
is configured in the menu; “Switch Tools -> Configuration File
Upload/Download -> TFTP Configuration File Upload/Download”.
This information cannot be learned from the DHCP server.
❑ DHCP
The stack will get an IP address from a DHCP server which will
then be used to TFTP the configuration file from the server. If the
configuration file has a static IP address assigned in it, then the IP
address would be overwritten after the configuration file has
been loaded.
❑ TFTP
The stack will use the IP address it had prior to reboot to download
the configuration file from the server through TFTP.
