Each Solaris host in a cluster has its own IP network multipathing configuration, which can differ from the configuration on other hosts in the cluster. IP network multipathing monitors the following network communication failures:
The transmit and receive path of the network adapter has stopped transmitting packets.
The attachment of the network adapter to the link is down.
The port on the switch does not transmit or receive packets.
The physical interface in a group is not present at system boot.
