<title>Cluster Connectivity Monitor</title>
<h1>Cluster Connectivity Monitor</h1>
The Cluster Connectivity Monitor (CCM) monitors failures in the two
Ethernet private
    <a href="sc/private_net">interconnect network</a>
links.  If one of the links fails, CCM automatically reconfigures the
networking drivers to use the remaining link for all traffic.  CCM
supports upto 2-node clusters.<p>

On SCI-based interconnects, CCM is not used.  Instead,
Session Management Agent <a href="sc/sma">(SMA)</a>
is used to reconfigure the networking drivers on link failure.<p>
