Modify the Host Name
Issue the hostname command in the command-line interface to give the new controller a unique hostname.
(The flash restoration process gave the new controller the same name as the existing controller.)
Do not save the configuration or write to memory at the end of this step.
(host)(config) #hostname <hostname>
Modify Topology Settings
This is required when migrating to a newer controller model. New controller models such as the W-7000 and W-
7200 Series controllersuse a different port numbering scheme than other Dell controllers. Ports on the newer
controller models are numbered slot/module/port. Older controller ports are numbered slot/port. As a
result, flash backup files restored from older controllers onto a newer model controllers can cause the newer
controller lose network connectivity, as the imported port settings don't match up with the controller
hardware. Additionally, all ports will become untrusted when you import a configuration from an older model
controller to a newer model controller.
Use the interface range and switchport commands to reconfigure the VLANs and IP interfaces to match the
port scheme of that hardware model. To avoid network conflicts, this process must be completed before the
controller is connected to the management network.
If you are replacing a controller with the same controller model, you can skip this step and continue to Save your
Configuration on page 119
The following commands adjust the port configuration on the new controller .
(host) (config) #interface range gigabitethernet <slot>/<module-start>/<port-start>-<module-
end>/<port-end>
(host) (config-range) #switchport access vlan <id>
Because the physical ports don't match, the port trust is removed by default, and needs to be re-enabled. In
the example below, the Trusted column shows that the port trust is disabled for all ports.
(host) #show port status

Use the interface range command to re-apply port trust to all of the gigabit Ethernet ports on the controller.
Then issue the show port status command to verify port trust has been restored.
(host) (config) #interface range gigabitethernet <slot>/<module-start>/<port-start>-<module-
end>/<port-end>
(host) (config-range) #trusted
(host) #show port status
