/*
 * Example script to demonstrate how a configuration can be committed 
 * from op-script.
 * 
 * This script by default tries to deactive interface 'ge-0/0/2'
 *
 * (i.e) Commit the following configuration
 *         "set interfaces ge-0/0/2 disable"
 *
 * Parameters: $interface -> Interface to disable
 *             $silent -> Decides where the output will go. 
 *                          0 -> (Default) Output to stdout
 *                          1 -> Output to syslog
 *
 * Same script can be triggered from event-policy configuration to deactivate
 * an interface on some specific conditions.
 *
 * For Example: 
 *
 * The following event-policy will trigger this script when
 * PING_TEST_FAILED event occurs. (PING_TEST_FAILED will be genereated by rpm 
 * when the ping test is failed)
 *
 * This policy also demonstrates, how to restrict the execution of same script 
 * again and again because of multiple occurences of the same event.
 *
 * Here, the only first occurance of PING_TEST_FAILED will trigger the script
 * and the script will be triggerd again only when the PING_TEST_FAILED did
 * not occur in the last 5 mins (300 secs)
 *
