Reconguring Jumpstart and Normal Modes
On a new factory-loaded switch, the switch boots up in Jumpstart mode. You can recongure a switch to reload between Normal and
Jumpstart mode.
Jumpstart (BMP)
mode
The switch automatically congures all ports (management and user ports) as Layer 3 physical ports and acts as a
DHCP client on the ports for a user-congured time (DHCP timeout). This is the default startup mode. It is set
with the reload-type jump-start command.
Normal mode The switch loads the Dell Networking OS image and startup conguration le stored in the local ash. New
congurations require that the Management IP and Management Interface be congured manually. This mode is
set with the reload-type normal-reload command.
If a switch enters a loop while reloading in Jumpstart mode because it continuously tries to contact a DHCP server and a DHCP server is
not found, enter the stop jump-start command to interrupt the repeated discovery attempts. The startup conguration le stored in
the local ash on the switch is loaded as part of the stop jump-start command and Auto-Conguration mode is changed to Normal
reload.
The reload settings that you congure with the reload-type command are stored in non-volatile memory and retained for future
reboots. Enter the reload command to reload the switch in the current congured mode: Normal or Jumpstart mode.
• Reload a switch running BMP version 2.0 in either Normal or Jumpstart mode.
EXEC Privilege mode
reload-type {normal-reload | jump-start [config-download {enable | disable}] [dhcp-timeout
minutes]}
If you reload in Jumpstart mode, you can congure:
• config-download: Whether the switch boots up using the conguration le downloaded from the DHCP/le servers (enable)
OR if the downloaded le is discarded and the startup conguration le stored in the local ash is used (disable).
• dhcp-timeout: The amount of time the switch waits for a DHCP server response before reverting to Normal mode and loading
the startup conguration from the ash. The default time is
innity, which makes the switch continue to wait forever unless you
issue the stop jump-start command.
The range is from 1 to 50 minutes.
The default is the switch tries to contact a DHCP server an innite number of times.
• This command stops the jumpstart reload process while it is in progress and changes the reload type to Normal mode.
EXEC Privilege mode
stop jump-start
If the command is initiated while the switch is downloading an image or conguration le, the command takes eect when the DHCP
release is sent.
Example of Viewing the Congured Reload Mode
To display the currently congured Reload mode for a switch running BMP version 2.0, use the show reload-type or show bootvar
command.
Dell#show reload-type
Reload-Type : jump-start [Next boot :jump-start]
config-download : enable
dhcp-timeout : 10
Dell#show bootvar
