3.5 How the Network Manager Works
The purpose of the network manager is to detect and recover from network card failures so that
network services remain highly available to clients. In practice, this means assigning IP addresses
for each package to LAN interfaces on the node where the package is running and monitoring
the health of all interfaces, switching them when necessary.
NOTE: Serviceguard monitors the health of the network interfaces (NICs) and can monitor the
IP level (layer 3) network.
