Monitoring Link Status

Software and hardware error conditions can bring down fabric links. When all links connecting a
traffic manager to a backplane are down, the traffic manager will drop incoming traffic. If the port
is still up, the traffic manager will continue to drop data. NetIron R05.3.00 and later solve this
problem continuously running a software task on the LP that monitors link status. If it detects that
