Periodic log message generation for shutdown prevention

Generates periodic log messages for shutdown prevention.

You can raise a periodic syslog that provides information about loops in the network. When a loop is detected because of a loop detection protocol data unit (PDU), on a loop detection shutdown-disabled interface, the interface will never be put into an error-disabled state, but it will generate a periodic log message indicating that the interface is in the shutdown-disabled mode. The periodic syslog is by default generated at an interval of five minutes. You can change this interval as required.

You can globally specify the interval at which the loop-detection syslog message is generated if the loop detection shutdown-disable command is configured on the port. This configuration applies to all the ports that have shutdown prevention for loop detection configured.

During a log interval duration window, a log message will be displayed for the first loop detection PDU received on the interface. This means that there will be only one log message per port in an interval window.

To configure the periodic log message generation for shutdown prevention, follow these steps.

  1. Enter global configuration mode.
  2. Enter the loop-detection syslog-interval <num> command.
    The following command will set the syslog-interval to 1 hr. 
    device(config)# loop-detection-syslog-interval 60
