Configuring Interface Characteristics

Configuring the USB Inactivity Timeout: Example

This configuration terminates any active USB console media type in the stack. A log shows that this termination has occurred. This example shows that the console on switch 1 reverted to RJ-45.

*Mar 1 00:25:36.860: %USB_CONSOLE-6-CONFIG_DISABLE: Console media-type USB disabled by 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.

*Mar 1 00:34:27.498: %USB_CONSOLE-6-CONFIG_DISALLOW: Console media-type USB is disallowed by system configuration, media-type remains RJ45. (switch-stk-2)

This example reverses the previous configuration and immediately activates any USB console that is connected.

Switch# configure terminal

Switch(config)# line console 0

Switch(config-line)# no media-type rj45

Configuring the USB Inactivity Timeout: Example

This example configures the inactivity timeout to 30 minutes:

Switch# configure terminal

Switch(config)# line console 0

Switch(config-line)#usb-inactivity-timeout 30

To disable the configuration, use these commands:

Switch# configure terminal

Switch(config)# line console 0

Switch(config-line)#no usb-inactivity-timeout

If there is no (input) activity on a USB console port for the configured number of minutes, the inactivity timeout setting applies to the RJ-45 port, and a log shows this occurrence:

*Mar 1 00:47:25.625: %USB_CONSOLE-6-INACTIVITY_DISABLE: Console media-type USB disabled due to inactivity, media-type reverted to RJ45.

At this point, the only way to reactivate the USB console port is to disconnect and reconnect the cable. When the USB cable on the switch has been disconnected and reconnected, a log similar to this appears:

*Mar 1 00:48:28.640: %USB_CONSOLE-6-MEDIA_USB: Console media-type is USB.
