When loading the Dell Networking OS image, if the Dell Networking OS 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 you disable the
config-download parameter, the switch loads the startup-config from the local flash.
Domain Name Server
Set up a 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. For more information, refer to the
Dell
Networking OS Configuration Guide, the IPv4 Addressing chapter.
Switch Boot and Set-up Behavior in
Jumpstart Mode
When the switch boots up in Jumpstart mode all ports, including the 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. For example:
1 The switch begins boot up process in Jumpstart mode (the default mode).
2 The switch sends DHCP Discover on all the interface up ports.
