Step 3 If the interfaces are not up, do the following:
• Check the cabling.
• Enable the interface.
sensor# configure terminal
sensor(config)# service interface
sensor(config-int)# physical-interfaces GigabitEthernet0/1
sensor(config-int-phy)# admin-state enabled
sensor(config-int-phy)# show settings
