You can configure the console type to always be RJ-45, and you can configure an inactivity timeout for
the USB connector.

Configuring the Console Media Type

Beginning in privileged EXEC mode, follow these steps to select the RJ45 console media type. If you
configure the RJ-45 console, USB console operation is disabled, and input always remains with the
RJ-45 console.
This configuration is global and applies to all switches in a stack.
Command
Step 1 configure terminal
Step 2
line console 0
Step 3
media-type rj45
Step 4
end
Step 5 show running-configuration
Step 6 copy running-config startup-config
This example disables the USB console media type and enables the RJ-45 console media type.
Switch# configure terminal
Switch(config)# line console 0
Switch(config-line)# media-type rj45
This configuration immediately terminates any active USB consoles in the stack. A log shows that this
termination has occurred. This sample log shows that the console on switch 1 reverted to RJ-45.
*Mar
system configuration, media-type reverted to RJ45.
At this point no switches in the stack allow a USB console to have input. A log entry shows when a
console cable is attached. If a USB console cable is connected to switch 2, it is prevented from providing
input.

by system configuration, media-type remains RJ45. (switch-stk-2)
