File Server
Set up a file server and ensure connectivity.
The server that holds the boot and configuration files must be configured as the network source for the
switch. The switch recognizes HTTP, TFTP, FTP, and Flash URLs.
For example:
• tftp://serverip/filename
• tftp://hostname/filename
• ftp://user:passwd@serverip//mypath/filename
• ftp://user:passwd@hostname//mypath/filename
• http://serverip/filename
• http://hostname/filename
• flash://filename
• filename (Assumes TFTP)
When loading the FTOS image, if the FTOS image on the server is different from the image on the local
flash, the switch downloads the image from the server onto the local flash and reloads using that image.
Next, the switch tries to load the configuration file. If the configuration file is not specified or if the
config-download parameter is disabled, the switch loads the startup-config from the local flash.
Domain Name Server
Set up a Domain Name Server (DNS) to determine the host name applied in the switch startup
configuration when no configuration file is retrieved from the DHCP server. The DNS server is contacted
only when no configuration file is contained in a DHCP server response and the host name is not resolved
from the network-config file on the switch. Refer to the FTOS Configuration Guide IPv4 Addressing
chapter, Resolution of Host Names for information.
Switch boot and set-up behavior in Jumpstart Mode
When the switch boots up in jumpstart mode all ports, including management ports, are placed in L3 mode
in a
no shut state. The switch acts as a DHCP client on these ports for a period of time (dhcp-timeout). This
allows the switch time to send out a DHCP DISCOVER on all the
interface up ports to the DHCP Server in
order to obtain its IP address, boot image filename and configuration file from the DHCP server.
