Hi John,

In my case I had to create a script for ping test and if ping not 
respond then to do a down and up in interface.

#!/bin/sh
while true ; do
if ! ping -n -c 1 186.xxx.48.2; then
    if ! ping -n -c 1 186.xxx.61.2; then
       if ! ping -n -c 1 186.xxx.54.2; then
          if ! ping -n -c 1 177.xxx.240.253; then
             /sbin/ifconfig ix0 down
             /sbin/ifconfig ix0 up
             echo "`date`" >> /root/ix.log
             echo "`netstat -in|grep ix0|grep 1500`" >> /root/ix.log
          fi
       fi
    fi
fi
sleep 10
done
